Question about Sharp R-1481B Microwave Oven
I have a Sharp R1481. Everything operates normally except the oven does not come on. The following do operate: lights, timer, clock, and hood exhaust system. This oven was experiencing problems intermittently until now. If the door was pushed in or "wiggled" the oven would operate. I checked the door switches and found one switch to be slightly melted. I have replaced all three door switches. However, the oven is still inoperative. Any suggestions are appreciated.
When you enter the time then hit START, does the turntable motor come on? If not, then I would suspect the secondary interlock switch, its mount, or its wiring. If so, then it's hard to say, unless there was some miswiring somewhere. The original problem sounded like just a classic bad door switch. At this point I suspect the wires on one of them may not have been reconnected exactly where they were. It does matter. I would suspect the secondary interlock switch, which MAY have white/white and grey/grey wires attached. Also, one of the switch mounts may have a broken tab that makes the switch move so it's not getting activated. At our site, we have the service manual for the R1830, which is similar to the R1480-series. We have that plus *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
