Question about Whirlpool GH7145XF Microwave Oven
We have check the breaker and power supply, they were the first thinks we checked before the inline fuse. Anymore suggestions.
So is it dead? (No life, no beeps, no lights?)
A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open.
When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
