Could be the motor, coupling between the motor and turntable, or the controlling device (possibly a relay).

The turntable motor will need to be replaced, a common issue with most brands.

Replace the turntable motor, it is defective and will only get worse.

Hi,

You can buy the turntable online here:

http://www.partstore.com/Part/Sharp/Sharp/R403HW/Sharp/Sharp/NTNTA108WREZ/New.aspx

For model R-1752, it did not use a separate turntable coupler, the coupler is part if the turntable support, which is part number FROLPB025MRK0 (note ohs and zeroes).

You can order one from either Encompass here (for less but not in immediate stock) or from the
Sears Parts Direct Web site (costs more but is shown in stock).

I've uploaded the service manual to our site here to help you.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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

You will need to remove the motor to get it off.

We have the full R-930AK/AW service manual for this model and have uploaded it to our site here to help you.

You will need the free Acrobat Reader to view or print it.

Here's the procedure:

1. Disconnect the oven from power supply. Remove the turntable tray, and the turntable support out
of the oven cavity.
2. Turn the oven upside down and remove one (1) screw holding the turntable motor cover to the base plate and take off the turntable motor cover.
3. Disconnect wire lead from the turntable motor.
4. Remove the two (2) screws holding the turntable motor and coupling mounting plate to the oven cavity bottom.
5. Turntable motor, Coupling mounting plate and Thermal protection plate bottom will be free.

We have the complete service manual on our site: http://www.microwavedisplay.com/r930ak_aw_sm.pdf It contains all the safety, disassembly and part information you should need. You can order a new turntable motor (and likely a new "motor packing" grommet, and perhaps a new coupler) at Tritronics at http://www.wehaveparts.com
