MT4155SPQ4 Whirlpool Microwave - Instructions

ordered a new tray

Watched a you tube video prior to installing new switch. Followed the video which gave me confidence i was up to the task. After removing the touch pad I found my design was not exactly like the you tube model but I found the defective switch, replaced it and put the microwave back together. Works great. Again watch the videos

discovered upon further inspection the the plastic shaft coming out of the turning motor was melted. Had to stop repair and order that part

Replaced Door latch Bracket.
Filed a bit off the bracket connection fingers so to fit into the slot.

Remove from cabinetry, take cover off and had a very difficult time removing the plastic form that has the switched in. Replace the lowest of all the switches, and then again very difficult time getting the plastic form back in. Some of the plastic even broke during the process but not any that could prevent it from working as it did before. I had ordered a fuse, 2 packs of 2 switches as there are 3 switches but only had to use 1 to get it working again. Tested after switch install, put the cover back on and reinstalled in the cabinet.

Removed M/W oven case/cover. Identified part needed. Found part online with in 2 minutes, ordered new door latch actuator, installed with part arrived within two minutes, reattached case/cover, reinstalled M/W.

Replaced the diode (aka wire-vltge) in the HV circuit after removing cabinet cover using both the secure torx screw drvr & phillips head screw drvr. The hardest part of the job was finding the secure torx nut drvr tool on the internet & purchasing same.

I received my glass cooking tray so fast but when I try to put in the microwave did't fix was to big,I call you today to return and very nice lady help me and told me I need to call whirlpool and explain them and already order again thank so much for all your help you have very nice people in customer service. Thank you so much again. !!

OMG! I wish everything in life were so easy.....The cooking tray of our 15 year old microwave cracked and I swore it'd be impossible to find a replacement. That is until I discovered Partselect.com!!All I had to do was input the appliance brand and part I was looking for, and there is was. Thank you, Partselect.com!!

The tip on the end of the latch broke off, so I had to carefully pry it back in without breaking the new piece. Took a few tries, but got it.

All the electrics worked on Amana microwave EXCEPT for the cooking function. Inspected the control board and found the upper switch on the door interlock was burnt. Installed new switch in minutes and everything now works fine. Unfortunately, had to purchase expensive two switch "kit" although only one switch was kaput. PartsSelect mailing was SUPER fast. Thanks for looking, Scott

Just took the plate out the packaging & rinsed,dried and put in the oven. I was so happy I found it @partselect online& it came in the next day or two. Will definitely use them again. It was a fraction of the cost from local parts store.

Placed in micro Great sevice. Thanks

My wife was pushing a few buttons with her knuckle (hands were full)and the microwave just turned off. Just like we had blown a breaker. First I unpluged it. Then I removed the phillips screws of the front panel, and found and removed the ceramic fuse. 3 days later I received the new fuse in the mail, and put it in. I plugged the microwave back in and it works great.

Great!! I set the new tray into the microwave and was done! This site has the best service I have ever seen! I'll be back when something else breaks, it is just a matter of time.
