wmh1164xvs-2 micro doesn't heat up
 
micro doesn't heat up. I think it the thermal fuse or the magnetron. what do you guys think?

What it does and what it does not besides heating?

Does it make any unusual noise?

The microwave doesn't make any noises and everything works perfect except for the inability to heat up food.

The problem can be a bad magnetron thermostat, a bad magnetron or a bad control board. You have to have a simple multimeter to perform some tests. Let us know when you will be ready.

Gene,

I am having the same problem with my Microwave/Oven combo (MODEL# KEMC377KBS0) and would like to try and determine which component needs replacing. Once i have a multi-meter, will you be able to give me instructions on how to test the components?

I'm pretty confident I can replace which ever component is bad - once i figure out which one is faulty.

Thanks for any help you can give...

Hi Bryan,

We definitely can guide you through the troubleshooting process. Let us know when you will be ready.

Thanks Gene,

Couple quick questions to get me started.

1) I'm assuming I need the oven to be connect to power before I can test the components, correct? The reason I ask, is because the oven is currently in my garage waiting to be installed in another house.

2) If you were to make an educated guess what the top 3 components that may be bad causing the microwave to run fine but not heat-what would those be? I'm thinking I may go ahead and buy them so i can have them on hand sooner and just return what i don't use. My thinking is go ahead and purchase the Magnatron and the fuse. What else would you suggest i purchase.

3) Do you recommend i get a Digital or Analog Multi meter.

thanks

1) It's very good to have it in a garage for troubleshooting and/or repair. You will need the oven powered up only at the final step to see if it's fixed or not.

2) So far it is unpredictable.

3) I really don't see any difference. You can find more information in of our previous threads: http://forum.appliancepartspros.com/...-ohmmeter.html

Thank Gene,

So i'm ready to start testing. I've accessed the microwave compartment where the Magnetron and other components are located.

I've discharged the capacitor (as best as i can tell the capacitor had no energy stored. it's been sitting a few weeks)

I have my Digital Multi-meter and have check the fuse (#27 in this diagram) it appears the fuse is fine.

What would be the next thing you would check?

How do you test the magnetron?

Hi Bryan,

Attached to this post you will find some instructions as well as the tech sheet with the wring diagrams.

You also have to check both fuses, the door switches, the cavity thermostat (TOD) and the magnetron thermostat (TOD). All of them have to be checked for continuity.
