The turntable motor of a microwave allows you to rotate your dish and distribute the waves on it, for balanced cooking.
The motor may be faulty or underpowered, due to faulty wiring. It is difficult to repair this part, so it is better to replace it.
The main failures that occur on this part are:
- The microwave no longer spins / the tray no longer spins
- The microwave makes noise.
The motor is the only part of the microwave where access is from below. On some devices, it is enough to cut out a small plate, on others it is necessary to completely unscrew the lower panel.
A microwave’s rotating tray plays a significant role in evenly heating your food. The motor powers this tray, and when it fails, you might notice the tray no longer spins. But fear not, replacing the motor is a task you can manage on your own with a bit of patience and the right tools. This article will guide you on how to safely replace the motor of a microwave tray.
Please Note: Working with electrical appliances can be hazardous if not handled with care. Always prioritize safety and consider seeking professional help if you’re uncomfortable with such tasks.
Tools You’ll Need:
- Screwdriver set
- A new motor compatible with your microwave model
Steps to Replace the Microwave Tray Motor
1. Unplug the Microwave: Safety comes first. Before you begin, ensure the microwave is unplugged to avoid any risk of electrical shock.
2. Remove the Tray and Coupler: Take out the glass tray and the plastic coupler underneath it. The coupler, which connects the motor to the tray, usually just lifts out.
3. Access the Motor: The motor is typically located on the underside of the microwave. You’ll need to turn the microwave over to access it. Be sure to place it on a soft surface to prevent scratching.
4. Remove the Microwave Bottom Panel: Use your screwdriver to remove the screws securing the bottom panel, then lift off the panel to expose the motor.
5. Disconnect the Motor: The motor will be connected to the microwave by two wires. Gently pull these wires off the motor terminals. The motor itself will be held in place with screws. Remove these, and you can lift out the motor.
6. Install the New Motor: Position the new motor in the same place as the old one, aligning the screw holes. Replace the screws to secure it. Reconnect the two wires to the motor terminals.
7. Reassemble the Microwave: Reattach the bottom panel and secure it with screws. Turn the microwave right side up.
8. Reinstall the Tray and Coupler: Replace the plastic coupler in the center of the microwave oven cavity, making sure it fits onto the motor shaft. Then, place the glass tray on top.
9. Test the Microwave: Plug in the microwave and test the rotating tray with a cup of water. It should spin steadily while the microwave is operating.
In conclusion, while a malfunctioning microwave tray can be inconvenient, replacing the motor yourself can be a cost-effective solution. This guide offers a way to tackle the problem independently. Remember, safety comes first when dealing with electrical appliances, and there’s no harm in hiring a professional if you’re unsure. Keeping your appliances in good working order not only ensures their optimal performance but also prolongs their lifespan.
