Sorry, we couldn't find any existing installation instruction that matched.
Thermostat quit.
Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.

I just replaced part wb21x10148 thermal fuse because the microwave would not heat but it would run. Now with fuse replaced the vent fan runs on high when the unit is plugged in stating it senses high heat and will turn off automatically. Will replacing the thermostat resolve this issue?

Hello John, Thank you for the question. I suggest testing the door switches. You can test the switches with a multi meter to check for continuity. Hope this helps, good luck with this repair!

One of the connections of the one thermostat PS3491479/WB20X10048 that is outside the magnetron has melted plastic/black heat damage to the plastic connector part of the wire. I'm definitely buying a replacement thermostat, what I'm wondering is if there is a corresponding plastic clip that can be crimped to the white wire that's damaged if I cut off the end part and recrimp it? (Trying to avoid buying a whole new wiring harness or taking apart the whole unit.)
For model number PT7800SH4SS

Hi Robert, thank you for contacting us. Unfortunately, the plastic clip is not sold separately, and you may need to purchase the complete wire harness, part number PS12722495, along with the thermostat, part number PS3491479. If you need help placing an order, customer service is open 7 days a week!
