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.

What You Can Check Yourself

Common Questions About Microwave Not Heating

Does this mean the same thing on every brand?
The underlying causes are largely shared — a microwave is a microwave — but the diagnostic route is not. Component layout, part numbers and service-mode access differ by manufacturer, which is why we keep a separate write-up for each of the 11 brands listed above.
Can I keep using it while this is happening?
If everything else works normally, short-term use usually is not harmful. But a persistent fault means something is actively failing, and running the unit through it can turn a small repair into a large one. A few days, not a few months.
How much does this repair typically cost?
It depends on which component is at fault. We charge a flat diagnostic fee and give a firm quote before any repair work starts — see our repair pricing page for typical ranges.
Do you work on brands not listed above?
Yes. The brands listed have their own write-up for this specific fault, but we service every major make. Our brands page has the full list, and if yours is not on it, call and describe the unit.
Do you offer a warranty on the repair?
Yes — every repair includes a written warranty of up to 1 year on the parts and labor performed.
Do you cover my part of Denver?
Very likely — we cover Denver and 64 surrounding cities, foothills included. See the full service area list.
