Question about Microwave Ovens

1 Answer

Just wanted to know if I have to take the unit down or if I can get at the turntable motor from underneath the unit. The turntable still goes around but it is making a noise and not at a constant speed. It is a Whirlpool model # GH4155XPB3.

On most microwave ovens, the motor is accessed from an inspection cover, underside of the oven.

Turntable doesn't rotate

Your turntable motor need replacement. tip upside down with dish removed and gain access to turntable motor from underneath.(remove power plug before you start working on the m/wave.) 2 screws hold the small t/table motor in place.Unscrew both and pull motor upwards. Quote the info on the motor for a replacement. I find cooking isnt effected in any wayexcept if you want to bake things like cakes. It then requires the t/table motor.

Turntable does not spin but everything else seem to work just fine

It is likely the belt broke or came off or degraded. Take cover off unit and check belt underneath.

Turntable won't turn anymore

The turntable has a drive motor which is located behind the panel that covers the BOTTOM of the oven. It could be that this small drive motor has failed. Replacing it should be simple and doesn't cost much. If the oven is mounted, you can leave it in place in most cases and just remove the bottom panel. Make sure the unit is UNPLUGGED before servicing, however. Please post back with your complete model number (located around the door opening) so I can be sure. I'm having a hard time locating any parts info and want to make sure I give you the right advice.

Spacemaker 1800 Turntable

If the noise goes away when you turn the turntable off, it sounds like you have a turntable drive motor that is going bad. They are fairly easy to replace and not terribly expensive. You can access the motor by leaving the oven in place and UNPLUGGED. Remove the bottom panel. You will need to remove the turntable coupler (the plastic piece that spins the glass carousel) and remove a few screws in order for the motor to come out through the bottom of the oven. There should also be a quick connect plug that plugs into the motor. The motor runs about $35 and the turntable coupler (if you wish to replace it as well), runs about $8. The part numbers are 769741 and 769278, respectively at I hope this helps you.
