    When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on? Any unusual noises? Is it louder or quieter than usual? We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here:http://www.microwavedisplay.com/mwd_ad_a...

Is this the unit with the door that swings down like a conventional oven?? I think it is. This sounds like a door switch but could be a magnetron or cook relay on the control PCB.

We have a sharp r-9h84b convection microwave and the carosel has stopped working when the tray is in place. Any thoughts the carrosel seems to rotate very slowly when there is nothing on it.


It's almost certainly a bad turntable motor.

The part number was RMOTDA079WRE0 but it is listed as no longer available.

In some cases, older microwaves are available locally at repair shops or on Craig's List.

If you want to keep your eyes open, this same motor was used in the following Sharp models:

R9A20
R9A50
R9H11
R9H60
R9H66
R9H71
R9H73
R9H76
R9H80
R9H81
R9H81B
R9H83
R9H84
R9H84B
R9H91
R9H91B
R9H93
R9H94
R9H94B

Good luck.

The carousel in our Sharp Microwave/Convection Oven suddenly stopped turning. Nothing seems to be blocking it--it whirls around when I push it. Any ideas?


Got someone to come look at it, and the motor for the turntable has burned out! We're ordering the part!
Thank you!

Sharp R-1871 microwave/convection oven. Microwave will not work


This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

Doesn't cook


sounds like the heater busted.How many Watts does the microwave have?But anyway you can get it fixed by a handyman or a maytag repair man.But your better off buying a new one for around $60-$110.

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

Clicking sound sporadically


That particular skillet is just too heavy a load for the turntable system to handle.

I would suggest a lighter skillet or a different container, otherwise, the motor or shaft or both will be damaged.

It is of course perfectly okay to put metal in a microwave (after all, that's what they're made of!) but you just have to do it only according to the instructions in the owner's manual.

And as you know, metal in convection mode poses no problem at all.

You just need to use a lighter or different container.
