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.

SOURCE: Kenmore 721 microwave fan turns on by itself

I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Kenmore microwave model 721.85033010 works fine except the exhaust fan comes on just out the blue for no reason and wont shut off without unplugging.

It turns itself on

Interlock switch If your microwave is turning itself on, the first thing to check is the interlock switch. This is usually the first thing to malfunction that could cause this issue. If the interlock switch is bad then it will need to be replaced.
Main control board If your microwave is turning itself on and the interlock switch is still working, the probable cause is the main control board. If the control board is defective it will need to be replaced.

But before throwing parts at it give these folks a call...

I have a kenmore microwave hood combination..2016 model # 79080333310. I cooked a bag of popcorn on the popcorn setting.

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.

I have a Kenmore Microwave Hood combination that will not heat. Turn Table works and fan comes on but does not heat. Did I press a wrong button? How do I get the microwave working again?

I suppose it is possible you pressed the wrong button - if you disconnect it from the power for a few minutes it should cancel whatever action you might have taken, though realistically it is more likely your microwave has developed a fault that is best tackled by the repair shop.

I got a Kenmore microwave hood combination model number 721.80032 is it a hood fan to and how do i just turn on the hood fan

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.

I have a Kenmore microwave. The vent will just start on its own and can't shut off

Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.
