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
Water boiling near 202°F rather than 212°F
Anything that steams or boils behaves differently at this elevation, and a cycle that never seems to complete is frequently altitude rather than a fault.
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.
