FAN WONT SHUT OFF

Deanna:

There is a door sensor in the door frame of your microwave that tells the microwave if the door is open or shut. That sensor is not working for some reason. The sensor is near the latch mechanism and is made of plastic and has probably broken and needs to be replaced. I would take it to a small appliance repair shop. Microwaves are nothing to fool with if you do not know what you are doing.

The model number 721.80032 is a partial model number; it indicates the build series. I found the Kenmore microwave, 721.80032700. The final 3 digits indicate the panel color and similar details.

Assuming the microwave was installed properly, it should work as a hood fan. Press the touch pad with the fan icon (underneath it says Hi/Low/Off) to get the desired fan speed. The icon is on the lower left of the control panel; it's below the Cook Time button and to the left of the Light button.

The manual for the 721.80032700 is available here: https://www.searspartsdirect.com/partsdirect/user-manuals/72180032700-kenmore-parts-manual?manualIndex=0 . The direct link to the Owner's Manual is https://c.searspartsdirect.com/mmh/pd_download/lis_pdf/OWNM/L0710653.pdf . See pages 9 and 14 for using the exhaust fan.

I hope this helps.

With the full model number, chances are we could have helped you more.
If the cooktop lights recently failed, it may need circuit board repair.

Or it may be a failed hood TCO.

SE stands for System Error, this means that the keypad has a short in the membrane and must be replaced to correct the problem.

I HAVE KENMORE 665/61629 LIGHT STAYS ON. AND DO NOT COOKS. AND THE FAN DOES NOT WORK.

check the control unit and high voltage circuit, and megnetron, high voltage diodes, wiring and high voltage fuse etc.,
