Question about Whirlpool Microwave Ovens

1 Answer

Our microwave oven is a Whirlpool Model #MH6110xBB-5. After using it the other day it did not shut off. It makes a continous low humming sound with the door shut and will blow the fuse. I replaced the fuse and have to leave it unplugged or leave the door open. It takes about 10 t0 15 seconds to blow the fuse if I shut the door. It hums as if something is stuck. Can I repair this myself? What could be causing this?

The most cost effective way to deal with this is to just replace the oven.

SOURCE: High pitched hum/buzz

By high-pitched, you mean it is not that same frequency as when it's cooking? Is the tone near or the same as the beep you hear when you press a key? Please post a little more information so we can help better.

I would suspect the high-voltage transformer in this case, but the capacitor may be failing.

The high voltage section uses and generates voltages that can be instantly lethal.

So I don't recommend that anyone work in this area unless he has either a lot of experience or at the minimum, a good understanding of the safety issues and procedures involved.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa:

Also, there should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here:

Here are some links you or a friend can use for test help, but read the safety warnings first:

SOURCE: Makes a loud humming sound and blows fuse behind controll panel

Most likely a shorted capacitor is causing the fuse to blow. Easy and cheap to fix.

SOURCE: Microwave humming when you shut door

Do the inside light, turntable and internal cooling fan ALL come on when the door is closed (without pressing any keys) , or just one or more of those?

Does it actually heat when you shut the door (without pressing any buttons)?

(You can put a cup of cold water in it for a minute to test it)

I would first suspect a shorted door switch.

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

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.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's not a door switch issue, I would say it has a stuck relay on the control circuit board.

We regularly repair these for customers nationwide with our guaranteed $39.95 service in about a week.

Feel free to contact me directly for more information & help.

Humming sound when off

I also have the same microwave model and with the same problem. It is not quite 2 years old. I have a service call scheduled but did e-mail customer service at Whirlpool to inform them of this. Sounds like it could be defective model and a fire hazard. You should also inform them of yours.
