Question about Whirlpool MH7140XF Microwave Oven

Open Question

My Whirlpool Microwave Hood Combination model #MH7140XFQ-0 will cut off in 2 to 3 seconds when I add a minute or punch in the time. Everything still works-light comes on, table turns, time is still showing.The fan still comes on when I press the button. It just turns off and says 'power start?' with the time still there. I tried pressing on the door to see if that would help. What do you think? Jim

Does it make any noise, like buzzing ? Is there a burnt smell? If so it might be a shorted diode or perhaps the magnetron.

SOURCE: microwave not working

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

SOURCE: whirlpool microwave hood combination has code f2

The F2 error means you have a shorted membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

On these models, usually the membrane keypad is not available separately, so you would have to order and replace the control panel frame which comes with a new keypad (sometimes called "panl-cntrl").

The part availability and cost will depend on the full model number from the tag on the unit, and it will be one of these:

MH1150XMB0
MH1150XMB1
MH1150XMB2
MH1150XMB3
MH1150XMB4
MH1150XMQ0
MH1150XMQ1
MH1150XMQ2
MH1150XMQ3
MH1150XMQ4
MH1150XMS0
MH1150XMS1
MH1150XMS2
MH1150XMS3
MH1150XMS4
MH1150XMT0
MH1150XMT1
MH1150XMT2
MH1150XMT3
MH1150XMT4

You can order the part and find helpful exploded view diagrams here.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

"F6" on a Whirlpool microwave means you have a shorted cook relay on the control circuit board.

For model MH7140XFQ0 the control circuit board would be part number 4393919, which you can order from the Pros here for $132.23.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) take out the old board, then move the new circuit board into your frame.
