Frigidaire Microwave Turntable Wheel Assembly Melted or... | appliancefaults.com

Technical Background:

The microwave control unit (MCU) regulates power to the turntable motor, which rotates the turntable via the wheel assembly. Excessive heat buildup, often caused by arcing or prolonged use, can damage the wheel assembly. Improper cookware can also contribute to melting due to increased microwave energy absorption.

Symptoms:

The turntable wheel assembly in your Frigidaire microwave is showing signs of melting, warping, or deformation. The turntable may be sticking or not rotating smoothly.

Possible Causes:

Overuse of microwave for extended periods
Improper microwave-safe cookware
Arcing inside the microwave cavity
Food debris accumulation under the turntable
Damaged or worn-out turntable motor assembly
Excessive weight on the turntable

Solution:

1

Unplug the microwave from the 120V AC outlet. Use Lock Out Tag Out (LOTO) procedure.
2

Inspect the microwave cavity for signs of arcing or burnt food particles. Clean thoroughly with a microwave-safe cleaner.
3

Check the turntable motor assembly for any damage or signs of overheating. If the motor is faulty, replace it.
4

Ensure all cookware used in the microwave is microwave-safe. Avoid using metal or containers with metallic trim.
5

Replace the melted or warped turntable wheel assembly with a new, genuine Frigidaire part.
6

Test the microwave by running it for a short period with a microwave-safe dish containing water. Observe for any arcing or unusual noises.
7

Verify the voltage to the turntable motor is within the manufacturer's specifications (typically around 21V DC). Use a digital multimeter.

Safety Warning:

Disconnect the microwave from the power source before performing any repairs. Microwaves contain high-voltage components that can cause serious injury or death. Always use Lock Out Tag Out (LOTO) procedure and a digital multimeter to verify the microwave is de-energized before beginning any disassembly.

Prevention:

Regularly clean the inside of the microwave to remove food debris. Only use microwave-safe cookware. Avoid prolonged use at high power levels. Periodically inspect the turntable wheel assembly for wear and tear.

Expert Tip:

A common cause is splattered grease on the waveguide cover (usually mica) which can ignite and cause arcing. Use a 5/16-inch nut driver to remove the cover and inspect for grease. Clean or replace if necessary. Then run self diagnostics mode: Press 'Stop/Clear' then enter 1-2-3. A series of numbers will display. This is a basic function test and does not check all features.

Frequently Asked Questions

•How do I tell if my cookware is microwave safe?

Look for the microwave-safe symbol (usually a picture of a microwave with wavy lines) on the bottom of the dish. Avoid using metal containers or dishes with metallic trim.

•Where can I find a replacement turntable wheel assembly for my Frigidaire microwave?

You can order a replacement part from a reputable appliance parts supplier online or from a local appliance repair shop. Make sure to have your microwave's model number handy to ensure you get the correct part.

•What is arcing, and how can I prevent it in my microwave?

Arcing is the electrical discharge that occurs when microwave energy encounters metal or other conductive materials. To prevent arcing, always use microwave-safe cookware and avoid placing metal objects, such as aluminum foil or utensils, inside the microwave.
