I have jenn-air microwave oven model m167. Unit will come on and all programming works to heat food. Oven acts as if it is heating food,however it does not cook or heat food items. Any help with troubleshooting problem?

If the microwave oven is 7 years old or less the most likely problem is the magnetron, or the inverter board, cost consideration should be carefully thought out.

The problem is caused by one of three things, the magnetron "heats food" the high voltage diode "sometimes shorts" or the high voltage capacitor " shorts"

Hi!
I read your comment about needing to remove the control board to inspect it for damage. Looking at the diag. below, all you need to do is open the oven door and remove the two screws (#2 on diag.) fastening the brackets that hold the board in place and you can take it from there.

Refer to the diag. below If it was me, I would start by turning the breakers for both ovens OFF, then, in getting someone to help me pull the oven out, disconnect the power cord and check the power circuit protection devices like the fuse #4, located above the fan and the power board #25 also located on the back of the unit. Before replacing the blown fuse, inspect the wiring, If the unit is mounted over an oven that was in the Self Cleaning Mode that reaches temps. of about 500 degrees, there is a chance that a wire's insulation melted and shorted the unit.


If you need better resolution and the names and prices of the components on these diagrams, click on the following links: for the first diag: http://www.searspartsdirect.com/partsdirect/part-model/Jenn-air-Parts/Microwave-Parts/Model-JMC8130DDB/1266/0123100/M0512405/00001?blt=06&prst=0&shdMod=JMC8130DDB for the second diag: http://www.searspartsdirect.com/partsdirect/part-model/Jenn-air-Parts/Microwave-Parts/Model-JMC8130DDB/1266/0123100/M0512405/00004?blt=06&prst=0&shdMod=JMC8130DDB
I hope this info is helpful to you. If you need further assistance, just place a comment.

This is most likely the magnetron, the high voltage capacitor, or the power diode.

Replace the door switch I ordered mine at www.repairclinic.com

Is the interior flaking the only problem with it?

It can be sanded smooth and clean and dried thoroughly, then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Otherwise, if you want to replace it, I would suggest contacting Jenn-Air Customer Care here and telling them your model number.

They can probably give you the model number of a new "drop-in" replacement.
