Whirlpool MH6150XMS Stopped Heating and Turning

When I apply a little downward pressure on the handle the micro heats and turns. I assume I have a door latch or alignment issue. How do I fix this?

    Does the fact that the micro works when I apply downward pressure to the handle point to the door switch or can it still also be the control panel?

  • John Banks Jan 05, 2008

    OK, Here is where I am.

    1) I removed the consol to inspect the switches and latches.
    2) Upon visual inspection there are no broken plastic pieces and all three switches look and sound fine. The switching mechanisms all seem to engage properly when the door is closed.
    3) I removed the 3 switches to test for continuity. The upper and lower switches showed continuity when the switch was engaged. The middle switch showed continuity when the switch was not engaged. I believe they are all fine.
    4) I reattached everything and I still have the same problem. The micro lights up when I hit start, but I need to put downward pressure on the handle to get it to heat and have the carousel turn. I watched the switched as I applied dowward pressure and I did not notice anything getting engaged.

    Any ideas for next steps?

  • John Banks Jan 05, 2008

    Thanks. I just retried the continuity test using the door (instead of my finger). It looks like the top switch is the culprit. When the door is completely closed, there was no continuity. I applied pressure on the handle which seemed to lessen the pressure on the switch mechanism and voila - continuity.

    I then removed the switch again and found that if I push the mechanism all the way in with my finger, it does not show continuity, if I push it in 3/4 it shows continuity.

    Is this a faulty switch or and alignment issue?

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.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya:

    Door switch or door switch mount / alignment most likely, but once you've checked it out, if you need more help, please feel free to post back.

    Your continuity check was correct, but it still sounds like the door switch mount or door is a bit out of alignment or loose, or a plastic liece in the latch mechanism is bent or broken.

    I think you'll just have to look closer.

    The switch holder may be moved downward a bit or some of the plastic that holds the switch may be bent a little.

    I hate to sound like a broken record, but you just have to look it over very closely and use your best judgement at this point.

    It's hard for me to be more certain without being there on the ground.

    You're almost there...

THeood is not getting heated and the turntable is

the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron and turntable have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days, and electronics repair people are not cheap. hope this helps

My spacemaker just stopped heating food. What do

This is a microwave, correct?

I suspect the door lock interface switch(es) are burned out. Unplug it, be mindful of the 25,000 volts in the silver thing. Check the micro switches (look where the door closes on the top right side, probably) two positions, normally open or normally closed. check them for proper operation.

Micro switches are the most common of microwave failures because most of us open the door while the machine is running causing arc at the switch and burning up the little contacts.

My micro wave will not warm items up

You have not given much information, but it appears the Magnetron element (the heating device) in your oven has failed. Repairs are not cost effective my friend. New units are low priced and have many new features. Consider this.

Message for Chad

Hi. Your problem is most likely with the magnetron. I am guessing that it is going to need to be replaced. This is almost always the problem. Here is a link on how to test it.

Be sure and do both tests. You will need an Ohm meter (a multi tester will have an setting for testing resistance).

Just please use caution and discharge the capacitors!!! Working on ANY microwave poses a risk for shock if caution is not used.

MIcrowave oven stopped heating - Whirlpool MH6150XMS

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

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, which is very helpful when troubleshooting.
