KitchenAid KCMS145J Microwave Oven Repair

Most common issues on this model

  1. Printing rubbed off the keypad after many years of use
  2. Seal face chips that make the door appear slightly open
  3. A magnetron that heats slowly and unevenly
  4. A latch switch that fails to close, so the oven runs idle

By now, the KCMS145J has probably had its door opened tens of thousands of times, and the seal face and switches show it. Also sold as the KCMS145JBL and KCMS145JSS, it carries at least one revision on record, KCMS145JBL1.

Our approach is to look at the door before the cooking system. We check the seal face for chips, test each interlock switch, and see whether the latch pulls the door tight. Next, the panel: worn legends are cosmetic, but a pad that fails to answer is not.

Last comes heating. We warm a cup of water and time it, which tells us if the magnetron has weakened. Everything is priced in writing before we start, and our 30-day workmanship warranty stands behind the repair.

KCMS145JKCMS145J questions
Do worn keypad legends affect how the oven works?

Not directly, but they make it harder to notice a pad that is failing. We press and test each key against the control, and we replace the panel only if a pad has really stopped responding, not because the print has faded.

Why would a damaged door seal stop the oven?

The interlock switches expect the door to sit exactly right. A chipped seal face can leave it a hair open, so the oven refuses to start. We inspect the seal edges and the latch together.

Can you tell if the magnetron is weak by looking at it?

No. We heat a measured amount of water and compare the result with what a healthy oven does. Only after a poor result do we open the high-voltage side.
