Do-It-Yourself Stories from Customers like You Humming sound and burnt smell   Antonio F. • Miami , FL • June 08, 2018

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

Replace Thermostat on top of cavity. The thermostat is attached via 2 bending sheet metal tabs. Ours blew because the two wires connected to thermostat shorted, connectors melted. The short was caused by buildup of grease under thermal wire cover, shorting both leads. The unit is used heavily. This is the first thermostat to go. I had to replace wire connectors that connected to thermostat as well since the connectors were melted as well. Helpful hint. The grease build up was probably caused by... Read more

Do-It-Yourself Stories from Customers like You Intermittently microwave wouldn't power up   Richard S. • Mcfarland , WI • August 22, 2015

Removed OTR microwave. Checked the thermostat switches while power was applied with a DVM. Noticed that when a certain set of wires was moved the slightest bit the microwave would power up. Traced the wires to the thermostat switch for the cavity. Noticed that where one (of two) Faston terminals was crimped to the thermostat switch was black. (should be copper colored). That is a sure sign of arcing from a loose connection. Since the specification for the switch was to trip at 248F degrees... Read more

Turns out the thermostat that is on the side of the magnetron wasn't closed, so I took a butane torch and heated it up past the... Read more
