Auto fan does not work any more. All 5 manual switch settings of the exhaust fan still work. Is there a temperature sensor to turn on the fan automatically when it senses the heat during cooking on the cook-top. If yes, what is the part number and where is it located?

Answer Hi. There are three (3) Thermostats in your microwave, and neither has control of the cooling/hood fan. If the cavity thermostat "opens" everything would go blank/dead, until the thermostat cooled down and reset. If the magnetron thermostat were to "open" the microwave would not cook, until it was replaced. At this point it looks like one of the hood fan relays has a "sticky" contact, and you'll need to replace the control board W10259219. Thank You.
Auto fan will continue to run and cannot be shut off. When the fan button is pressed it says "fan speed hi will remain on untill no heat is senced". nothing is being cook on the stove and everything is cool

My microwave quit heating all other functions are fine.
How to know that I miss functional part? Thermostrat or Magnetron. What should I do?

Answer Edith, First you will need to remove the M/W from the wall, then remove the outer cabinet, so you can access and test the primary door switch, the MW relay on the control board and the thermostat on the magnetron tube, with a multimeter. You will need to be very careful, these are high voltage components and you can hurt yourself if you aren't careful. The additional information we sent you may be a bit more helpful. Thanks and Good Luck
