Hello, I have a Maytag microhood (MMV5165BAS). The cooling fan won't stop running. I have to turn the breaker off. This is the fan that runs on high for a few seconds at the end of a cook cycle. The microwave still works. It does have a vent fan but those buttons (on/off/speed) don't do anything to stop the fan. I researched it and replaced what according to the Tech Sheet inside the microwave is the Hood Thermostat, I discharged the capacitor first. On the online schematic the part I ordered was #17 DE47-20034A. However, this did not fix it. According to the Tech Sheet there is also a bottom thermostat and a cavity thermostat. The online schematic shows a total of 4 thermostats. I didn't want to spend the money on a new unit but it is 15 years old so there's a limit on how far I want to go. Any advice or guidance would be greatly appreciated.

I think the one in your second picture is the humidity sensor. It's difficult to tell as the image is so small.

Humidity Sensor



I think this might be the cavity thermostat.
