Fix a microwave that won't heat or shuts off unexpectedly. This thermal cut-off thermostat protects against overheating. DIY-friendly repair.
I measured the resistance between the two connectors on the magnetron: should be close to zero ohms and it was. I measured between the same connectors and the metal case: should be mega ohms, it was 15k ohms. That is a bad, partly shorted unit. I also checked the resistance of the thermal cut off, which should be zero but was 10 ohms so I replaced. The HV diode is checked with a 9 V battery (YouTube checking microwave HV diode) and it too was bad. Make sure to take pictures as you disassemble... Read more

APP was quick, the price was excellent and when I called their staff I found them to be friendly, knowledgeable and thorough! They had my parts to me in no time and I fixed... Read more

Oven won't heat after self-clean? This thermal fuse protects your oven from overheating. Replacement takes about 1 hour with basic tools. Video guide included.
Not sure which fuse might be bad, I ordered all three. The oven is almost twenty years old, so I figured it couldn't hurt to replace them all. The breakers marked oven were tripped, so we figured everything was off. Wrong! The 220 and the 120 are separate breakers. We found this out the old fashioned way, we got shocked. Anyway, the fix is pretty simple. Take off decorative trim. Only one screw on each side holds it on. Remove four screws securing oven to cabinet, and slide oven out. Our oven... Read more

If your oven won't heat past 250°F or stops heating completely, the high-limit thermostat may have failed. This safety switch is a moderate DIY fix.
The same thing happened about two years ago and when I took off the back cover, the high limit switch was melted and crumbling, so I replaced it and it's worked fine until a couple of weeks ago. We smelled a stinky electrical burning smell a couple of times and then it stopped heating past 250 degrees. Turns out the high limit switch was crumbling again. This time I replaced both the high limit switch and the bottom element and it heats up again like it should to any temperature. One of the... Read more
