Question about Sharp R-1460 Microwave Oven
Hi, I have read many of your posts and think that you could answer my question in your sleep. Here is my problem. I bought an older sharp microwave model r1641a at a sale and it is having a problem with the carousel moving. It is turned on but still doesnt move. I watched your video on how you cantell if it is the motor by turning it, but i still cant figure out if it is the support or the motor. Is there anyway to see if the motor is working or should i just buy both pieces and replace and be safe? The support looks like it is a little chewed up inside, but nothing seems to be trying to even turn. Any suggestions for me?
Isn't that actually an R1461A?
When you try to turn it by hand (as in the video) do you hear the motor whine? Is there resistance? Or does it just turn freely?
The hole in the turntable support should either be round with a flat side or a cross shape. If that's damaged, it won't work.
In some cases, the legs of the support get too hot and when the weight (food) is removed, they bend downward in relation to the hub.
I have solved this problem in the past by carefully heating the area where the legs meet the hub, using a gas stove flame or a torch.
Then I place it on a flat surface, weighted down so as to hold the legs so they will cool in the correct position.
If you have to do it more than once, the support should be replaced.
You can see if the motor is turning by removing the support and placing something wooden or plastic into the hole and see if it turns when you cook.
If you replace the support or motor, you should also replace the "packing" which is a rubber grommet.
You can find an exploded view here, and the parts list is here, but the best place to order Sharp parts is Tritronics.
To replace the motor, you need to remove the bottom panel of the oven, then remove the motor screws.
