my vent fan just stopped working, the display says the fan is on but nothing happens.

The problem could be a bad fan motor or a bad control board.

Perform the troubleshooting as described in the service manual (pages 7 & 10).

  • The part number for the control board is AP3951232

  • The part number for the fan motor is AP3964272

Whirlpool MH1150XMT-0 Fan will not run when oven is on unless you manually press fan and then only on high. No low speed. Bad door switch ? fan hi low switch or relay?

Hi Edwards,

Most likely the problem is a bad control board.

Here are the break down diagrams for the Whirlpool microwave Model MH1150XMT0

The fan on our Whirlpool Microwave MH2175xsq0 stopped running today. When I try to manually run it the word SOUP appears on the display. The rest of the functions on the control panel work fine. Down to the fan?
