Cooling fan assembly
Usually DIYVendor replaces this part if the oven is overheating
DIY.
Try this first — it costs nothing. Make sure the vent isn't just physically blocked by cabinetry or stored items before assuming the fan has failed.
Check, in this order
Feel for warm air at the vent while the oven is hot — silence there points straight at the fan.
Check whether the control panel is displaying a heat-related fault or shutting itself off — that's the electronics protecting itself from a dead cooling fan.
Before you open anything
Cut power at the breaker — most ranges and wall ovens are 240V and hard-wired, not plugged into a wall outlet, so unplugging is often not an option.
Let the oven cool before accessing the fan behind the control panel.
Tools
#2 Phillips screwdriver ($6) — Panel and bracket screws.
T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Remove the rear access or control panel housing to reach the fan.
Photograph its wiring before disconnecting.
Swap the fan and confirm it spins freely and quietly before closing up.
How you know it worked. Steady airflow at the vent whenever the oven is hot, and no more heat-related shutdowns or faults.
Prices are a snapshot taken on the date shown and are not monitored. Check the retailer before buying.
Worth fixing? Repair - the part is a small fraction of a new machine. Part $47.68 against $2,599.00 for a new machine (1.8%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Control panel
Usually DIYVendor replaces this part if it is damaged
DIY once the control board is ruled out as the actual cause of a total-panel failure.
Try this first — it costs nothing. Clean the panel surface and power-cycle at the breaker before ordering a part — both are free and both are common causes.
Check, in this order
Note which specific buttons or zones fail to respond — partial response points at the panel itself, total silence points at the control board behind it.
Wipe the panel and re-test; a spilled-liquid or grease film under a membrane panel mimics a dead button.
Power-cycle at the breaker for a full minute; a latched fault in the panel sometimes clears without any part.
Before you open anything
Cut power at the breaker — most ranges and wall ovens are 240V and hard-wired, not plugged into a wall outlet, so unplugging is often not an option.
Confirm the circuit is actually dead with a non-contact voltage tester before touching any wiring or terminal.
Tools
#2 Phillips screwdriver ($6) — Panel and bracket screws.
T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Open or remove the panel's access screws — usually behind the panel itself or through the oven's inner door frame, per the model's manual.
Photograph the ribbon cable and any wiring harness before disconnecting anything.
Swap the panel and reseat the ribbon connector fully — a half-seated ribbon looks connected but leaves half the buttons dead.
Restore power and run through every button and knob position before closing it back up.
How you know it worked. Every button, dial position and indicator responds correctly.
Prices are a snapshot taken on the date shown and are not monitored. Check the retailer before buying.
Worth fixing? Weigh it - this part is a meaningful share of a new machine. Part $371.18–$395.00 against $2,599.00 for a new machine (15.2%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Bake spark electrode
Technician onlyVendor replaces this part if the bake burner will not light
Stop. DIY within the open burner compartment. Stop and call a technician if you smell gas at any point or the burner won't ignite reliably after replacement.
Try this first — it costs nothing. Clean carbon buildup off the electrode tip with a dry brush — this alone restores plenty of these.
Check, in this order
Listen for a click or spark at the electrode when the oven calls for bake heat — silence points at the electrode or its wiring, a click with no flame points at the orifice or gas supply instead.
Look at the electrode tip for carbon buildup or a visible crack in the ceramic — either stops it sparking reliably.
Confirm the electrode's spark gap looks consistent with the old part; compare side by side before installing.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
If you smell gas at any point, stop immediately, do not flip any switch or light anything, leave the area, and call your gas utility or a licensed technician — this is never a DIY fix.
This is an open igniter inside the oven cavity, not a sealed combustion system — normal DIY caution applies, but never work on it with the gas left on.
Parts exist for this component and are deliberately not listed here: this is not a repair to attempt yourself.
Worth fixing? Repair - the part is a small fraction of a new machine. Part $9.99–$59.36 against $2,599.00 for a new machine (2.3%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Regulator valve
Technician onlyVendor replaces this part if the burners and oven will not light
Stop. STOP. Call a licensed technician. A gas pressure regulator fault is always a professional repair, never DIY.
Try this first — it costs nothing. Nothing free here.
Check, in this order
A weak, yellow, or unsteady flame across every burner, not just one, is the pattern that points at the regulator rather than a single burner part.
Do not attempt to test or adjust gas pressure yourself; this requires a manometer and training a homeowner won't have.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
If you smell gas at any point, stop immediately, do not flip any switch or light anything, leave the area, and call your gas utility or a licensed technician — this is never a DIY fix.
This is the assembly that sets gas pressure to every burner — installing it wrong changes how every burner burns and can produce carbon monoxide. This is not a DIY repair.

Worth fixing? Repair - the part is a small fraction of a new machine. Part $98.99–$162.79 against $2,599.00 for a new machine (6.3%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Convection fan assembly
Usually DIYVendor replaces this part if the convection function is not operating properly
DIY.
Try this first — it costs nothing. Check for anything, like foil or a dropped item, jammed against the rear vent cover before ordering a fan.
Check, in this order
Look through the rear vent hole while the oven calls for convection heat — no visible motion points at the fan or its motor.
Listen for a hum with no rotation, which points at a seized motor or a fan blade jammed against the housing.
Before you open anything
Cut power at the breaker — most ranges and wall ovens are 240V and hard-wired, not plugged into a wall outlet, so unplugging is often not an option.
Let the oven cool before accessing the rear cavity wall.
Tools
#2 Phillips screwdriver ($6) — Panel and bracket screws.
T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Remove the rear cavity cover to reach the fan and motor.
Photograph the motor's wiring before disconnecting.
Swap the fan or motor assembly and confirm the blade spins freely before refitting the cover.
How you know it worked. The fan runs whenever convection mode is selected and bakes come out even, not one-sided.
Prices are a snapshot taken on the date shown and are not monitored. Check the retailer before buying.
Worth fixing? Repair - the part is a small fraction of a new machine. Part $88.96–$89.00 against $2,599.00 for a new machine (3.4%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Broil spark electrode
Technician onlyVendor replaces this part if the broiler will not light
Stop. DIY. Stop and call a technician if you smell gas or it won't ignite reliably after replacement.
Try this first — it costs nothing. Clean carbon buildup off the tip with a dry brush first.
Check, in this order
Confirm the bake burner ignites normally — if only broil fails to spark, the fault is isolated to this electrode and its wiring.
Look for carbon buildup or a cracked ceramic tip.
Check the electrode's wiring for a chafed or disconnected lead before assuming the electrode itself is bad.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
If you smell gas at any point, stop immediately, do not flip any switch or light anything, leave the area, and call your gas utility or a licensed technician — this is never a DIY fix.
Parts exist for this component and are deliberately not listed here: this is not a repair to attempt yourself.
Worth fixing? Repair - the part is a small fraction of a new machine. Part $16.99–$18.89 against $2,599.00 for a new machine (0.7%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Power cord
Usually DIYVendor replaces this part if the range will not power up at all
DIY if you're comfortable at a 240V terminal block. Get an electrician if you're not, or if the range is hard-wired rather than corded.
Try this first — it costs nothing. Check the breaker and the outlet, with another device, before assuming the cord itself has failed.
Check, in this order
Confirm there's genuinely no power anywhere on the range — a dead cord looks identical to a tripped breaker or a dead board.
Inspect the cord for a visibly burned, melted, or loose terminal end at the range's connection block.
Before you open anything
Cut power at the breaker — most ranges and wall ovens are 240V and hard-wired, not plugged into a wall outlet, so unplugging is often not an option.
Confirm the circuit is actually dead with a non-contact voltage tester before touching any wiring or terminal.
Tools
#2 Phillips screwdriver ($6) — Panel and bracket screws.
Non-contact voltage tester ($18) — Many ranges are hard-wired, not plugged in - confirm the circuit is actually dead before touching it.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Cut power at the breaker and confirm dead with a non-contact voltage tester.
Photograph the terminal block wiring before disconnecting the old cord.
Connect the new cord to the exact same terminals, matching hot, neutral and ground.
Restore power and confirm with the voltage tester before plugging in or reconnecting to the outlet.
How you know it worked. The range powers on fully and the display, controls and heat all respond normally.
Prices are a snapshot taken on the date shown and are not monitored. Check the retailer before buying.
Worth fixing? Repair - the part is a small fraction of a new machine. Part $61.29–$84.00 against $2,599.00 for a new machine (3.2%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Left front simmer orifice
Technician onlyVendor replaces this part if the simmer function on the burner will not work properly
Stop. DIY with careful leak-testing. Stop and call a technician if you smell gas.
Try this first — it costs nothing. Clean the small orifice opening with a soft brush or compressed air — its tiny bore clogs easily, and this costs nothing.
Check, in this order
Confirm the burner lights and runs fine at high heat — if only the low simmer setting won't hold a flame, the simmer orifice (a smaller, separate orifice from the main one on some burners) is the specific suspect.
Clean the orifice opening before assuming it's failed outright.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
If you smell gas at any point, stop immediately, do not flip any switch or light anything, leave the area, and call your gas utility or a licensed technician — this is never a DIY fix.

Display board
Usually DIYVendor replaces this part if it is not lighting up or responding to inputs
DIY once the main control board is ruled out as the cause.
Try this first — it costs nothing. Reseat the ribbon connector between the display and the control board — a jarred connector is a free fix that looks identical to a dead display.
Check, in this order
Confirm buttons and knobs still respond, a beep or a relay click, even though nothing shows — that isolates the fault to the display board rather than the main control board.
Check the ribbon or wire connector between the display and the main board before replacing the display itself.
Before you open anything
Cut power at the breaker — most ranges and wall ovens are 240V and hard-wired, not plugged into a wall outlet, so unplugging is often not an option.
Confirm the circuit is actually dead with a non-contact voltage tester before touching any wiring or terminal.
Tools
T20 Torx driver ($7) — Some control and door assemblies use Torx rather than hex.
#2 Phillips screwdriver ($6) — Panel and bracket screws.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Access the display board, typically directly behind the control panel.
Photograph its connector before disconnecting.
Swap the board and reseat the connector fully.
How you know it worked. The display shows correctly through every mode and setting.
Prices are a snapshot taken on the date shown and are not monitored. Check the retailer before buying.

Right front/center spark electrode
Technician onlyVendor replaces this part if the left front/center burners will not light
Stop. DIY. Stop and call a technician if you smell gas or the burner won't ignite reliably after replacement.
Try this first — it costs nothing. Clean carbon buildup off the tip with a dry brush first.
Check, in this order
Confirm other cooktop burners spark normally — one dead burner among several working ones isolates the fault to that burner's electrode.
Look for a cracked ceramic tip or carbon buildup.
Check the electrode's spark gap against a working burner on the same range.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
If you smell gas at any point, stop immediately, do not flip any switch or light anything, leave the area, and call your gas utility or a licensed technician — this is never a DIY fix.

Broil tube orifice
Technician onlyVendor replaces this part if the broiler in the oven will not light
Stop. DIY with careful leak-testing. Stop and call a technician if you smell gas.
Try this first — it costs nothing. Clean the orifice with a soft brush — debris is a common, free cause of a weak broil flame.
Check, in this order
Confirm the broil burner ignites but runs weak or uneven — that pattern points at the orifice, not the electrode.
Clean the orifice opening before assuming it needs replacing.
Before you open anything

Right front orifice
Technician onlyVendor replaces this part if the burner will not light
Stop. DIY with careful leak-testing. Stop and call a technician if you smell gas.
Try this first — it costs nothing. Clean the orifice with a soft brush before ordering a replacement.
Check, in this order
Confirm the burner sparks but gas flow is weak, uneven, or absent at that one position while others are fine.
Clean the orifice opening before assuming it's failed.
Before you open anything
Shut the gas supply valve behind or under the range before disconnecting anything on the gas side.
