This is the same repair as the condenser or evaporator fan once you've identified which one is meant; if neither fan is actually at fault, move on to the damper or control board.
Try this first — it costs nothing. Vacuuming a clogged condenser coil (if that's the fan involved) fixes the same symptom for free - try that before replacing any fan motor.
Check, in this order
Figure out which fan the manual actually means before ordering anything - open the freezer and hold the door switch in to listen for the evaporator fan, then check the rear condenser fan separately.
Vacuum the condenser coils first if that's the fan in question - a clogged coil causes the identical warm-fridge symptom for free.
Spin the blade by hand: seized or noisy means replace, free and quiet means look elsewhere.
Before you open anything
Unplug the refrigerator.
Tools
5/16" nut driver ($8) — Cabinet and bracket screws on most front-load machines are 5/16" hex.
#2 Phillips screwdriver ($6) — Panel and bracket screws.
Flashlight ($0) — Boot, sump and pump housings are dark.
Phone camera ($0) — Photograph connector positions before unplugging anything.
The repair, in order
Identify which fan is actually implicated (condenser, at the rear or underneath, or evaporator, behind the freezer panel) before ordering a part.
Remove the relevant access panel and locate the fan motor.
Confirm the blade is seized or the motor is silent when it should be running.
Photograph the wiring, unclip the motor, and fit the replacement.
How you know it worked. The fan runs whenever it should (with the compressor, or with the door switch held in), and the affected compartment returns to temperature.

Worth fixing? Repair - the part is a small fraction of a new machine. Part $19.94 against $1,399.13 for a new machine (1.4%).Part cost only. A service call adds a regional diagnostic fee plus labour.
Power cord
Usually DIYVendor replaces this part if it is damaged or missing
This is a straightforward owner swap; if the outlet itself is warm, scorched, or trips repeatedly, that's an electrical issue beyond the fridge and worth an electrician's attention.
Try this first — it costs nothing. If a tripped breaker or GFCI is the actual cause, resetting it is free - confirm the outlet is live before assuming the cord itself has failed.
Check, in this order
Confirm the outlet itself has power - test it with another device or the non-contact voltage tester before suspecting the fridge.
Inspect the full length of the cord and plug for fraying, melting, or a loose prong.
Check the cord's connection point inside the fridge (often behind a rear access panel) is seated and not scorched.
Before you open anything
Unplug the refrigerator before inspecting or handling the cord.
Never plug a cord back in that shows melted insulation or scorch marks - replace it instead.
Tools
Multimeter ($25) — Confirm continuity before replacing an electrical part.
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
Confirm the wall outlet is live and not on a tripped breaker or GFCI.
Inspect the full cord and plug for visible damage.
Test the cord for continuity end to end with the fridge unplugged.
If replacing it, photograph the internal connection before disconnecting, fit the new cord, and route it the same way.
How you know it worked. The fridge powers on immediately when plugged in, and the connection stays cool to the touch after running for an hour.

Configuration-matched to this machine (bottom-freezer, automatic, ~21.8 cu ft). Prices are UPC-verified Amazon listings, not estimates. Like-for-like replacement rarely pays for itself on energy alone — replace for fit and features, or because the repair maths above says so.
