What causes it, and what each fix costs
Thermal cut out tripping
A thermostat protecting the magnetron shuts things down when it overheats. Usually a symptom of an airflow problem rather than a faulty thermostat.
Cooling fan failing
A weak or seized cooling fan lets the magnetron overheat within minutes. Fixing the fan fixes the shutdowns.
Blocked ventilation
Cabinet clearance, a dust blocked intake grille or a saturated filter, the free version of this fault.
Failing magnetron drawing excessive current
A tube on its way out can overheat and trip protection before it dies outright.
Intermittent door interlock
A switch dropping out mid cycle stops everything instantly, usually with the display still lit.
Repair or replace?
Check the free causes first, clearance around the unit, a clean intake grille and clean filters resolve a fair share of mid cycle shutdowns. If the cooling fan or magnetron is genuinely at fault, apply the usual rule. Repair over the range and built in units, replace countertop ones.

We'll quote you on hauling it away, or buying it.
Not every microwave is worth repairing, and we'd rather tell you that than sell you a repair. If you're replacing it, we'll give you a free quote either way. Scrap pickup for a machine that's finished, or a cash offer if it still has life in it. Working units, recent models and premium brands are often worth real money.
Quick Questions
It works again after it cools down. Does that confirm overheating?
It is a strong indicator. A fault that clears after a cool down period and returns under load is thermal protection working correctly, which means the real question is why it is getting that hot.
Could it be the outlet rather than the microwave?
Occasionally. A microwave sharing a circuit with other heavy loads can trip a breaker mid cycle. If the display goes completely dark rather than the unit simply stopping, check the breaker first.
