Troubleshooting A Faulty Microwave Turntable: How To Fix It


What's crackin', folks? If you're having trouble with your microwave, fear not! We've got some tips and tricks to get that bad boy back up and runnin'. Don't be stressin' over cold leftovers - we got you covered.

Testing Three Terminal Switches

First up, if your microwave ain't turnin' on at all, it might be a problem with the three terminal switches. But don't worry, testing them is as easy as 1-2-3. Just grab a multimeter and follow these steps:

  1. Unplug the microwave and remove the outer cover.
  2. Locate the three terminal switches (they're usually near the door latch) and disconnect the wires.
  3. Set your multimeter to the "ohms" setting and test the switches one at a time by touching the probes to the terminals.

If you find that any of the switches have no continuity, that's likely the problem. Replacement switches are relatively cheap and easy to find online.

Why Isn't My Microwave Heating?

If your microwave is turnin' on just fine, but your food ain't getting hot, there could be a few different issues at play.

First, check to make sure that the door is closing properly. If it's not sealing correctly, the microwave won't start heating. If the door seems fine, next up is the magnetron. This is the part of the microwave that actually creates the heat, and if it's not working, your food ain't gettin' hot.

If you suspect the magnetron is the problem, it's best to call in a professional. This ain't a DIY fix, and you don't want to risk makin' the problem worse.

Fixing a Turntable

If your microwave's turntable ain't spinnin', that could be a problem too. Lucky for you, it's usually an easy fix.

First, remove the glass tray and inspect the plastic drive bushing. If it's worn or broken, you'll need to replace it. You can usually find replacement bushings online or at a local appliance store.

If the bushing looks fine, next up is the turntable motor. To check this, remove the motor and test it with a multimeter. If it's got no continuity, it's likely the problem.

Again, replacement motors are usually pretty easy to find and relatively cheap. Just be sure you get one that's the same size and voltage as your old one.
