Microwave will not start. Everything works but start button
For model number WMH31017AS1
Hello Sue, thank you for your question. We would recommend testing the door switches first. Sometimes, the door switches will fail and the until will not start if they do not activate. If the door switches are tested and are fine, the issue would probably be with the touch pad or the control board for the unit. I hope this helps!

I purchased the recommended bulb for the countertop light under the microwave. It will not screw into the socket. The serial number is s-n-tr24649898 on the microwave. The base seems to be too large and will not screw in. Do I have the incorrect bulb. This is the bulb recommended by Lowe's as well as this site.

During normal operation the microwave intermittently turns on and off
For model number WMH31017AS1
Hi Dennis,
Thank you for your question. If the microwave shuts off intermittently you may have a defective or loose door switch. There are 3 listed for your microwave and you will need to test them for continuity. Before testing them with a multimeter, unplug the microwave from the electrical outlet. Once the microwave has been unplugged, you will need to remove the cabinet surrounding the microwave in order to access the door switches. Take this opportunity to inspect the door hooks that trigger the door switches to verify that they are activating the switches mechanically. To test the switches for continuity, set your multimeter to Rx1, depress the actuator button and touch the terminals with the probes. You should receive a reading of 0, indicating that there is continuity. If the switch does not have continuity between the terminals, you will need a replacement door switch. We hope this helps! If you have any questions, please let us know.
The nightmare was that this microwave is installed under the cabinet....in order to get to the light bulb I had to pull out my stove then squeeze into the space between the stove and counter....my old microwave light bult was much easier to change.....Shame on Whirlpool for making this so difficult.....must be a better way to cover the li

Ordered top & bottom micro-switches and mounting plate parts. Internet reviews could not find specifics if the issue was due to a top/bottom or combination of micro-switch or mounting plate failure. Pulled the plug. Removed the top vent assembly cover held in by 2 Phillips screws inside the vent. Removed the control panel held in by 1 P
... Read morehillip screw at the top vent assembly area. Lifted control panel upward to release the catch and moved it off to the side - didn't disconnect any leads. Used a Torx bit to remove the door switch mounting plates at the front and pulled the plates through the opening from the control panel. Documented the wire color code connections, the top plate uses 2 micro's with one using both the closed & open contact. Installed the respective micros on the mounting plates and worked backwards with the wiring and removal steps. Once completed, the open/close sensing has worked every time.
