Door switch

Check, in this order

1. Confirm the door closes firmly and the latch hooks aren't bent before blaming a switch.
2. Test each switch for continuity in and out of the door-closed position — most microwaves have two or three separate door switches and only one may have failed.
3. Listen for a click as the door closes; a switch that doesn't click is the one to replace first.

Before you open anything

• Unplug it — do not work on the door switches with the cord connected.
• These are the safety interlocks that stop the magnetron when the door opens; match the exact part, not just 'close enough.'

Repair or replace? Repair first once the listed checks confirm this component. It is usually a contained repair; reconsider replacement only if multiple major faults or a disproportionate technician quote are present.General guidance for this component — no model-specific price maths behind it.

Broil element

Check, in this order

1. Confirm this is a broil/convection symptom, not a microwave-heat symptom — plain microwave mode heats fine but broil doesn't.
2. Look for a visible glow difference or a section of the element that stays dark.

Before you open anything

• Unplug it and leave it unplugged.
• On a combination microwave/oven, the broil element compartment is behind the same shell as the high-voltage side.

Heating element

Check, in this order

1. Confirm this is a convection-mode symptom — plain microwave heat works but convection/bake mode doesn't get hot.
2. Note any burning smell, which changes the urgency.

Before you open anything

• Unplug it and leave it unplugged.

Temperature sensor

Check, in this order

1. Note whether the oven/convection side overshoots, undershoots, or never reaches set temperature — this pattern helps distinguish a sensor fault from an element fault.

Before you open anything

• Unplug it before doing anything else.

Thermostat

Check, in this order

1. Note whether it cuts out mid-cook or refuses to reach temperature at all — both point here but mean different things to a technician.

Before you open anything

• Unplug it and leave it unplugged.

Fuse

Check, in this order

1. Test the outlet with another appliance first — a dead outlet or tripped breaker looks identical to a blown fuse.
2. Note whether the failure followed a pop or smell, which points at a diode or short rather than a simple overload.

Before you open anything

• Unplug it before doing anything else.
• The line fuse is normally reached by removing the outer cabinet cover, which exposes the high-voltage capacitor — this is not a simple bulb-style fuse swap.
