Question about Whirlpool MH1170XS Microwave Oven

1 Answer

Whirlpool Microwave no longer heating

The turntable turns, lights work, everything seems to work except it is not heating. It is 4 years old under the limited waranty which will pay for Magnetron if that is the problem. Service wants $145 to repair if it is the magnetron. Otherwise $62 visit applied to repair. Could it be fuse instead? I think I can replace a Magnetron but of course Whirlpool said I would need to use approved service to get the Magnetron paid. Looks like magnetron for my unit is $45. Microwave will not heat. Everything else works almost 2 yrs with this product.

    Instead of replying with a useless post or a flip answer, I like to actually help posters in a constructive, thoughtful way.

    First, a couple of questions:

    Any unusual noises? Is
    it louder or quieter than usual?



    We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

    Also, if you or someone you know can and want to test things further, here are some links you
    or someone you know can use (in order given) for test help, but read
    the safety warnings first:

    (if it is NOT shorted or burned looking,
    it's probably fine)



    http://www.gallawa.com/microtech/mag_tes...
    (continuity can be good even
    though it is bad!)

Sounds like the magnetron has failed. It is the magnetron that generates the microwaves that heat the food. If it or the circuit that powers it fails then it stops heating. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.

Less than 5 years old - Microwave Panel lights up, turntable turns, fan works - everything works except it doesn't heat food. Heard a pop, and now it runs louder than before but doesn't heat. Any ideas?


That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.

Please rate my response if it was helpful to you.

Thanks, Repairman45.

Whirlpool MH3184XP Microwave Turns On, Heats, but sounds like fans not working. 4 years old, fans worked fine until they seem not as loud anymore. The magnetron is working fine as it heats (did the 1 cup...


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.)

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

Whirlpool MH1150XMQ 1000 Watts Microwave--NO HEAT


About 95% of the time it is the magnatron. If the microwave is under 5 years old that part is often covered under warranty. I would check your manual. If not the p/n is 8206335 and it's about $80 and fairly easy to install. I just looked and the magnatron is covered.

Labor to replace it would be about $125

Microwave turntable won't turn


Most likely the turntable motor itself is bad - not an uncommon problem for that model.

Check with www.martinmicrowave.com (toll free 1-877-894-0035)

unfortunately, the particular motor used in your model is rather expensive - + - $50

Turntable doesn't turn


If you just purchased and Installed the microwave, I would call Sears and tell them what is happening, generally, it would still be under warranty if less than a year old. If its a countertop model, you may have to take it in, otherwise they should come to the home for the repair. I would also NOT indicate that you have looked at it as that would void your warranty.
Otherwise, it seems like the problem could be, a) touchpad , b) a relay or c) the main control board
