Oven Convection Fan Not Working? 6 Causes and What to Do
A convection fan that will not spin is usually a failed fan motor, a seized blade, a door switch or a relay on the control board. Here is how to narrow it down.

Why is my microwave turntable not spinning?
A microwave turntable stops turning for 4 common reasons. The glass tray is not sitting on the center coupler, food or grease is stuck under the roller ring, the plastic coupler is cracked or worn, or the turntable motor under the cavity has failed. Some models also let you switch the turntable off by mistake.
Over-the-range and built-in microwaves are worth fixing in most cases. Our Mountain View appliance repair technicians service GE, Whirlpool, Samsung, LG, Panasonic, Sharp and built-in drawer models from Bosch and Wolf.
If the tray spins but the food stays cold, see microwave not heating. If you see sparks, stop and read microwave sparking first.
What should you check first?
- Turntable button. Many over-the-range models have a "Turntable On/Off" key. Make sure it is on.
- Tray seated right. The bumps under the glass tray must sit in the slots of the center coupler.
- Roller ring. It should sit flat in its track with all wheels turning freely.
- Weight. A very heavy dish can stall a weak motor.
What are the 4 most common causes?
1. Tray or ring out of place
After cleaning, the tray often goes back slightly off the coupler. It then sits still while the coupler turns under it. Lift the tray and set it down until it drops into place.
2. Food or grease under the ring
Spills dry into a sticky layer in the track. The wheels drag and the tray stops. Wash the ring and the tray in warm soapy water, and wipe the cavity floor clean.
3. Cracked or worn coupler
The coupler is the small plastic piece in the center that links the tray to the motor. Its notches wear down or crack over time. A new coupler is a cheap part.
4. Failed turntable motor
If the coupler does not move at all during a cycle, the motor under the floor may have failed, or a wire to it has come loose. This part sits close to high-voltage components.

What can you try safely?
- Check the turntable button on the control panel.
- Remove the tray and ring and wash both.
- Clean the floor of the cavity and the coupler.
- Reseat the ring and tray so the tray locks onto the coupler.
- Test with a cup of water for 30 seconds. Never run the microwave empty.
Do not open the outer case. A microwave holds high voltage in its capacitor even when unplugged. Any work under the cavity, including the turntable motor, should be done by a trained technician.
When should you call a technician?
Call if the coupler does not turn after cleaning, if the motor hums but nothing moves, or if the turntable stops along with other problems like no heat or a dead display. Most microwave repairs in Mountain View cost about $120 to $350.

Frequently asked questions
Why did my microwave turntable stop spinning?
The most common causes are a tray that is not seated on the coupler, food or grease under the roller ring, a cracked coupler, or a failed turntable motor. On some models the turntable has its own on and off button.
Is it safe to use a microwave if the turntable doesn't turn?
It will still heat, but food heats unevenly, so stir and turn it by hand. Do not run the microwave empty. Stop using it if you see sparks, smell burning or hear loud buzzing.
Can I replace a microwave turntable motor myself?
On most models the motor sits under the cavity behind panels that are close to high-voltage parts. The capacitor can hold a dangerous charge even when unplugged, so this repair is best left to a technician.
How much does microwave repair cost in Mountain View?
Most microwave repairs in Mountain View cost about $120 to $350 with parts and labor. Built-in and over-the-range models are often worth repairing.
