MMV1164WS1 Maytag Microwave - Instructions

Removed top vent panel....black plastic runs the length of the microwave....3 Phillips screws. Removed front right panel one Phillip screw on top right. Lift up to remove lifts off the catches. Unplug some of plug connectors on the back of the control circuit board to have room to swing it out of the way to gain access to the interlock switches. Take pictures of all disconnections and wire connectors removed from switches. There or two interlock banks of switches my problem was the top one. Remove the switch bracket held in with one star drive screw and a plastic catch on the switch bracket actuator...there is a slot in the frame the actuator slides into. Replace switches and reverse procedure to reassemble.

Replaced both switches on the top door latch. Diagram shows the two switches on the lower latch? No success. Still had same message on the display. Replaced lower switch, fixed the issue.

The hard part was trying to find the light bulb locally. The locally sold light bulbs were either too long, not dual element or not powerful enough. So I ordered the light bulb straight from PartSelect. When it came time to install the new light bulb I carefully removed the screw holding the plate in position so as not to loose it in my gas stove. I needed the mirror to line up the light bulb and screw it in. Once it was in I verified operation and closed up the plate being careful not to drop the screw into my gas stove. Problem solved.

Remove two screws from Vent Grille, one on either side, and remove one screw inside Vent Grille on right side. Pull Vent Grille off exposing the two Charcoal filters. Remove the two Charcoal filters by hand and replace with new ones. Reinstall the Vent Grille and tighten screws. That's it. I'm not handy (ask my wife) and if I can do it so can you.

issues started when door opened light would flicker then come on disassembled checked switches with a meter determined switch was faulty figured I'm in here replace them all because if one fails others will follow be careful removing actuator assembly plastic is brittle (remember this is above the stove subject to heating and cooling) plastic isn't as pliable installed all the switches perfecto oh by the way disassembled the faulty switch found contacts had arced from opening door while microwave is running use the buttons to stop will eliminate further issues

BEWARE: KMHS120ESS takes two charcoal filters. This site doesn't tell you that! I only figured it out after ordering one, receiving it, and removing the vent cover to replace it. So then I had to order another one and pay for shipping a second time (which cost almost as much as the filter itself). C'mon PartSelect, why are these not sold in a pair?

Remove top grill assembly and replaced filters,parts were delivered on time and fit as expected, Job well done!

I looked up a YouTube video of someone with a similar over the oven microwave. That helped me get into the area behind the control panel where the door switches are. I checked the springs and the cam rocker? The thing that actually hits the button on the switch when the door closes. They were in good condition so I assumed the door switch was bad. There are two so I just purchased one figuring (hoping) that only one was bad. And lo and behold only one was bad. Bing bam boom. Put it all back together and I'm set. Not too difficult. Took a week of work because it takes like 50 days to ship. My kitchen looked like a hurricane after image because of all the parts scattered everywhere.

Instead of telling you, i have question do you have any instructions on how to do the repair. It would have helped save time on the repair.

This job took longer then it should have, becasue I did not start right in the begining. I did figure it out quickly after the wrong start.

You were a big help in picking the right part to correct the problem. You should be able to help with the repair. Thank You

I ordered the part according to the Model number, inserted the part very easily, (and I am soooo challenged in that area) and now it turns again. :)

Bracket fit perfect! Quick install! Great service...got the item within a day. Perfect!

The original bulb came apart while unscrewing it from the back of the microwave, leaving the metal screw thread contact still in the socket. Since this is an over-the-range micriwave there isn't enough room to manuever needle nose pliers into the socket to remove the screw thread contact. So this is how we were able to remove it.
Unplug power cord.
Take a standard wine bottle cork and whittle down one end until it fits in the socket. Then, using a bit of pressure push the cork into the socket snd begin unscrewing the screw thread contact until it comes out of the socket. Works like a charm!

Got some info from the PartsSelect web site and a short YouTube video about how to replace the socket. (Even at 74 years old I'll be darned if I'll pay for a service call if I think I can do the repair myself). Unfastened all the panel screws, swung down the rear-hinged lower panel carefully, then took a couple of pictures showing which wires went to which side of the light socket -- and to the underside of the turntable because those pulled off by themselves when I lowered the panel). Pried off all the silicone sealer around the socket using my fingers, got the old socket out and replaced it, put the wires back in place, refastened the drop-down panel. It was a very easy, straight-forward task that would have taken <15 minutes were it not for the fact that my old eyes had trouble seeing all the screws, even with a flashlight. Everything works fine now.

Followed instruction already on your website

Used the 2 original screws. Good thing I saved them. The screws were not provided with the new part.
