Microwave ovens use a magnetron to emit radio waves which travel through a waveguide (attached to the side of the interior cavity wall) before entering the cooking area. Once inside the cooking area, the radio waves cause water molecules within the food to vibrate intensely, generating heat that cooks the food from the outside. By rotating the food during this process, the turntable allows the radio waves to cook the food more evenly. Without a properly working turntable, you may find that chicken breast to be pleasantly warm on one end and cold on the other.
Because of the high voltage and high current used by microwave ovens, be aware that repairing this appliance poses a substantial risk for injury or death if precautions are not taken. You should always unplug the microwave before you attempt any disassembly. Since high voltage capacitors used in microwaves may retain a charge even after the microwave has been unplugged, we recommend that only experienced professionals access and replace internal components.
Repair Clinic has the appliance parts to keep the turntable turning, including replacement glass trays, turntable motors, drive couplings, support rings, touchpads, and control boards. But you’ll want to make sure you’re selecting the correct part that works with your particular microwave, whether you depend on a stand-alone, built-in, oven/vent hood combo, or convection model manufactured by GE, KitchenAid, Frigidaire, Samsung, LG, Kenmore, or Panasonic. Start by entering the full model number of your microwave in the Repair Clinic website search bar to see a complete list of compatible parts. You can narrow that list by using the appropriate part category filter (such as Glass Tray, Coupler, and Support Roller) and the part title filter (Glass Tray Drive Coupling) to identify the exact part you need.
