LG Microwave Not Heating
Microwave Not Heating is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A seismic gas shut-off valve that has tripped
The Hayward Fault runs under this entire service area and Berkeley requires these valves at sale and on permitted work; when one trips above about magnitude 5.0 the range and oven die together and the appliance is fine.
A failed bake or broil element
The most common cause of a full loss of heat in an electric oven.
A drifted temperature sensor
Electronic sensors drift out of spec gradually, so the oven can run well off-target without any error showing.
