The magnetron is defective, cost to repair will probably exceed the price of a new one.

Sears Parts Direct has the parts diagrams and many parts for the R-1505 microwave. The glass plate is part 4-3 ($33.99) on this page: http://www.searspartsdirect.com/partsdirect/part-model/Sharp-Parts/Microwave-Parts/Model-R1505/0958/0123370/50019999/00001?blt=06&prst=&shdMod= .


Without more tests, I can't be completely positive but the turntable motor is the likely problem. That is part 1-4 on the list above. However, it could be a wiring problem with the wiring to the turntable motor.

Partstore.com has many of the parts as well: http://www.partstore.com/Model/Sharp/Sharp/R1505.aspx .

I hope this helps.

1st check the temperature fuse ( item 1-3 on this diagram)
If fuse is good have the HV rectifier item 1-1 checked.
If both check out good the most likely problem after that is the magnatron item # 1-8

Hi, if this unit is over the stove it has to come down. Table top, case has to come off. The monitor switch is a microswitch that is part of the door switches. PLEASE UNPLUG YOUR UNIT BEFORE WORKING ON IT. When you get it opened up, there's probably a diagram that will let you know which switch it is. Lookd it up and does list a monitor switch with fuse, but would not give me a part number. Hope this helps
