Fan not working on Whirlpool microwave Model MH2175xss1

Turntable works, the unit heats but after a few minutes it quits heating. I suspect that is because the fan doesn't work. Fuse was good, but replace anyway. What can I do next?

What do you mean "fan doesn't work"? Magnetron will over heat without fan.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

The most common cause of that is a shorted or blown high voltage rectifier diode.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and your magnetron is still under the part warranty, but you would have to pay labor.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

d:%5cele%5crepair%5cmicrowave%5cge_hotpoint%5cmini_manual_behind_grille_small.jpgdee77f7.jpg

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html

If it's within the magnetron portion of the warranty (5-9 years) but out of the original full warranty (1 year), G.E. will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it's within the mag warranty, G.E. should send you the magnetron to do it yourself. Call them at 888-239-6832 with your model, serial, and manufacturing date.


If nothing else, you can save about $50-75 if you remove it from the wall and take it to a GE-authorized servicer.

You can find a GE-authorized servicer by calling GE Appliance Service at 1-800-848-7620 or here.


Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Fan failure /Intermittent heating


quite likely your microwave is trying to prevent it self from self destruct, because if the fan is not keeping the electronics components cool enough while its running the high limit thermo will disconnect power from the heating circuit, if the fan is not working it should be replaced , that's a techs job.

After approx a minute a regular squeak begins, occasionally missing a beat.Heating is fine.


If the "frequency" of the squeaking is a low frequency, the I would suspect the turntable motor or stirrer motor (if so equipped).

If it is a higher frequency, I would suspect the cooling fan or hood fan motor.

Suggest you pull the plug out, remove outer cover and place a cup of water into the micro. Set power to minimum then switch on and take note if the fan works or not. If not, switch off immediately and have it replaced(magnatron will burn out if left to run without fan.)

Not Heating. Fan, turntable, light working.


I would definitely suspect the door locking mechanism in this case. If it was the sensor it would start and then stop within a short time.

The starter switch should click if you have the door open and time it for 01.seconds and press start. So that is the secon component to think of.

Whirlpool MH1140XM: has power, but no heat, turntable not spin.


Test the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
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.

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
