Door switch is bad on my Whirlpool microwave

How do I go about fixing a bad door switch? From what I've read on this website, it appears as though thagt is my problem. I have a Whirlpool MH1140Xm above the range model and would hate to have to buy a new one if this is something that can be easily fixed on my own or by someone else. Thanks!

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Rmc305pdq2 door error


please use this stpeps and fix it. God bless you
  1. nspect the power cord Unplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switch If your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fuses To determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motor Locate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Microwave has stopped heating, yet grill and convection oven still work.


A model number would have helped, but I can give you a generic answer.
It may be a bad door switch or mount.
(Anybody in the home opening the door while it's cooking?)

My microwave will not shut properly. The top latch will not completly close. The microwave still runs... but It will not heat food and it makes a clicking noise. Can this be fixed or should I purchase a...


Hi, quite often this is due to a bad door switch located inside behind the area where the door hooks go into the oven.
Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure.
In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see from time to time, and we repair those nationwide for $32.50, but it's usually a door switch.


It can be fixed......

I have a Whirlpool Microwave that runs when I open the door Model# GT4175SP. Any ideas?


Remove the case and confirm that the door latch switch is mechanically intact. Next, disconnect the switch and test it with an ohm meter to see that it is actually working. It should show a short (0.0 ohms) when the door is closed and no reading when the door is open. Those readings could be reversed but there should be two distinctly different readings when testing the switch. If you don't see any differnce between readings when the door is open or closed then replace the switch. This should solve your problem.

Whirlpool MH3184XPS over the range microwave coming on when using hood light


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.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.
