KIRK - For model number KCMS2055SSS1
January 13, 2023
Unit does not seem to heat consistently. Heating an item may take 4 minutes one time and 5 minutes another (like bacon). A medical eye compress will take 10 sec to get very hot and the next time it is hardly warn at 10 sec.
Chris Boyle Profile
Hello Kirk, thank you for contacting us. It looks like the magnetron, part number PS11731447, is not functioning uniformly. The issue can also be related to a faulty diode, part number PS11747959. These two parts are the most likely culprits of the issue. You can test these parts with a multimeter. Please follow safety precautions before doing the repair. Customer service is available 7 days a week if you require assistance placing an order. Thanks again for reaching out!

microwave door stuck....wont open

  • Sailendra from Round Rock, TX

The reason the door would not open upon pressing the door opener is because the BRCKT-LATCH was broken. I discovered that after opening the microwave enclosing. The BRCKT-LATCH has two ends sticking out....each fits into a hole. One of the ends on the LATCH was broken and therefore it was not tightly fit. No upon pushing the door opener t he LATCH would not function properly since it was loosely fit and hence the door would not open.
To Fix this issue:
1) Buy a new BRCKT-LATCH
2) Remove the microwave enclosing. I had to use a special screwdriver, since the screws were security protected on my microwave. After removing the case, I opened the door by manually pressing the door latch upwards (please make sure that the microwave is not connected to the electric socket before removing the enclosing).
3) pull out the old LATCH from the microwave.
4) carefully insert the new LATCH. Try not to put too much pressure when trying to fit the latch, or else the ends may snap again!!
5) Close the door and try opening it by pressing the door opener. it should work now!!

Microwave worked intermittently depending on how door was closed

Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and a lso took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

The repair went well...I am so glad that I read this info before buying a new microwave....it saved me lots of money. I did have a repair man come and look at it and he told me to buy a new one but it cost alot of money when it wasn't necessary. I did the repair and I was very proud of myself.
Three men watched a woman fix this and it was no problem...they were impressed also....
