Model # UMV1152BAQ,S/N 10406839EN Linkage to sprocket that turns turntable appears to be disconnected
If the oven is STILL heating, but the carousel isn't turning, this problem is commonly attributed to a turntable motor that has worn out and may need to be replaced. The motor is attached to the center plastic piece (called a turntable shaft, turntable ring or coupler) under the middle of the glass tray. The following link explains how to access and replace the motor:

This is a very simple repair, that usually is not expensive. The price will be determined by the model and manufacturer. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.
You can refer to any of the following websites for comparison:

The first three sites listed have helpful exploded view diagrams to assist you with locating and properly identifying the part(s) you may need.
The average price for a motor is about $35 to $45. If your model number is not listed at all the sites, use the part numbers from the Sears site and use them for your search criteria. The model numbers don't always cross reference, but the part numbers do. The part number for a replacement turn table motor for the model you have listed is W10207571 (listed as item 22 in the parts drawing under the "Internal Controls" parts section.
NOTE: Even though the carousel may not be turning, you can still use the microwave while awaiting parts. You will need to physically rotate whatever you are heating about midway through the cook time to ensure even heating. Early model microwave ovens were not equipped with a rotating carousel and this was the common procedure.
Replacing the turntable motor.
The motor assembly is fixed to the base
of the oven usually with two screws and access i obtained by removing
the inspection plate directly beneath the motor. It is usally a plug
in synchronus motor that revolves at a few revs per minute but the
plastic cogs in the motors gear box fail and the motor assembly must
be replaced. They are fairly inexpensive and obtainable usually from
a domestic appliance repair shop.
If you feel confident,
disconnect it from the mains power, remove anything in the cavity and
turn it upside down if it is a tabletop model, a little more
complicated if it is built in!
Remove the inspection plate and
disconnect the motor. Remove the motor and go and get a new one. Re
fit it and put the microwave back in its position. Plug it back in,
with the turntable and plate. Put a cup of water on the plate inside
of the oven and heat for 20 seconds to check the plate goes
round.
Hope this helps.
