The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

We have the service manuals for this model and have uploaded them to our site here and here to help you.

My Sunbeam Microwave SGB8901 lights up and seems to be working, but it doesn't heat anything. Is this fixable?


Only 2 years old? Hopefully you still have owner's manual, troubleshooting section should help you look for the problem. Hopefully, there is a circuit breaker, or perhaps a fuse. I hope it was not used with a metal object accidentally. No help? Check with Sunbeam Customer service, be nice, they usually are helpful.

HELP! On 12/11/12 I purchased a SHARP 2.2 cu ft stainless steel microwave (order # BBY01-540643080878, SKU# 6035052)for a Christmas gift for my 75 yr old mother...now just after one yr, it's not working...


There is a warranty on all Sharp items. If it is out of warranty by a few days, contact Sharp, not their repairer, ask for advice. You may be pleasantly surprised.

My sharp R1870 microwave/convestion oven turns


This is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample drawing for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

Sharp Microwave Lights Up, But Won't Rotate or Cook


Hi. I would suggest checking out the door switches. There are usually 3. If one of those has failed then the microwave won't operate because of safety reasons. Best to replace all three. If the display on the unit is still fully operational I'd say go for the repair.

Our microwave/convecton turns itself off after about a minute


This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.

Microwave not heating up


Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Dacor dcm24s.light, fan, and control panel work but turntable and heat do not


Most likely the bottom door switch. Dacor units are built by Sharp and that switch is a very common problem. You'd either need to check the switch with an ohm meter or remove the cover of the switch to see if it's burned inside.
