MT4155SPQ1 Whirlpool Microwave - Instructions

I took the microwave out of the cabinet compartment and placed it on the counter. I removed the torx screws from the back and the two phillips head screws from each side. I then pulled the cover back and off. I removed the broken latch piece by pushing it away from me until the outside nipple was free and then pulled the piece out. I opened the door by pushing up on the latch with a flat head screwdriver. I put the end of the new part into the area behind the latch and on top of the microswitch and pushed until the outside nipple would slide into the slot. I then replaced the cover and secured with the screws taken out initially. Done.

The power on the microwave went completely out when I went to use it, but there was no power failure for the house or neighborhood. We removed the microwave from above the oven. Took out the screws on the sides and back of the microwave and slid the top back. The line fuse was located on top unobstructed, NOT behind the button panel like some microwave models. As the appliance is over 20 years old the line fuse was quite old. It was really hard to pry it out of its holder and actually broke. I used a vacuum to suck up the dust and glass and it was easier to get out the ends once the middle broke. Popped the new line fuse in, slid the top back on, put in the screws and put the microwave back in its compartment above the stove. Good as new!! We were about to spend money on a new microwave, but thankfully I came across this site. So happy I did!!

This repair was really easy. The part that took the most time was taking it down from it's compartment above the oven and putting it back up there once repaired.

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

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.

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

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.

I'm so glad that the site was available on the internet!
I simply threw away the broken turntable and inserted the new.
I did not have to wait for a repair person!
Great! Thank you.

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 called to make sure I was replacing the correct part. I paid over the phone and it came the next day. Very very easy process.

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

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.

I had purchased the wrong replacement tray from Amazon and could not find the right one on their website. Yours was exactly what I needed.

very easy just put the tray on the turntable. excellent delivery service arrived sooner then expected.

It literally took me longer to unpackage the fuse than to install it. I removed the outer shell by unscrewing the five screws, lifted it off and set it aside. The old fuse was readily visible so I pulled it out and put the new one in its place. I set the shell back on and replaced the screws. I plugged it in and ran it for 30 seconds while still in the shop just to make sure that solved the problem and presto - it worked like a charm. A $20 part saved me from having to purchase a new microwave (sadly, I had to break the news to the wife).
