Front vent on JMV8208A Jenn-Air Over-the-range microwave hood keeps opening

Greetings, everybody.

I have just finished installing the JMV8208A micorowave oven, which comes with room recirculating configuration out of the box. I have completed the convesion to the yop-vented configuration with external vertical duct, and it is blowing up the ventilation duct properly.

Now there is no need to open the top front vent, as there is nothing coming back to the room. But the microwave oven keeps opening oit whenever fan is engaged.

I am looking for a way to keep the front vent closed.

Any thoughts?

    The best JennAir could do was to suggest a paid service call.

    Instead I carefully removed the outer cover and unplugged the module responsible for opening and closing the front vent (it can be seen through the front vent on the left side of the slot). No other modification was required, and this modification is reversible, if there is a future need to convert the microvawe back to the front-venting mode.

    The problem is now solved.

There may be an option to turn that off with the keypad, but your best bet would be to contact Jenn-Air.

The manual will have their contact info or you can see:

I have a Appollo AAC24-BIB halftime oven. one of the 2 wires coming from the t stat arced and burnt off and burnt the connection off. Customer service sent me a new t stat and I put it together and ran it...

The cover may be contacting the wires - this will complete the circuit and cause a short. You may need a new part - this time install and ensure that no bare wires are making contact with the cover.

Error code E-21 Jenn Air convection microwave

That code says to first check your oven temp. sensor probe connection and ohm it out with an ohm meter, it should read about 1100 ohms at room temp.

If thats ok, then it says the problem is your relay board.

Need help in installing the back bracket on the wall for my jmv8208bas

If you do not have the original template you can hold the back plat up on the wall and mark the screw holes. Try to get at least 3 on studs. It will have to be down from the cabinet a little to allow for the micro to swing up into place.

GE Microwave Profile Spacemaker Runs on its own

Your microwave turning on by itself is a "self preservation feature" of the GE Profile Advantium and maybe some other models. Read the manual, When your over the range oven gets warm enough, for whatever reason the venting fan comes on until a satisfactory oven temperature is reached. You are not permitted to shut the vent fan off. Also it seems a temperature near room temp must be achieved before it shuts the fan motor off, it is very annoying. We had to return our Advantium because of fan noise. I configured the ovens vent fan to the recirculate direction because we do not have a vent duct that exits the house over our range. When the vent fan acting as the ovens cooling fan automatically turned on we would have to leave the house to hear each other talk. Too bad we really liked the oven other than that major problem.
