Question about Sharp R-1480 Microwave Oven

1 Answer

Microwave oven inoperative

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. every thing works except doesnt heat.

No! I'am afraid not, the problem is in the keypad control board, the whole assembly must be replaced, the part alone will cost around $100.00 or more depending on make and model.

The light on the bottom of my r1481 microwave stays on constantly, how do i turn it off
The problem is a shorted relay no the control circuit board.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid with a one-year guarantee.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Our oven started coming on when the door was shut. It is not cooking but the light and the fan come on. Nothing makes it stop except opening the door. I unplugged it for awhile, but that didn't help...
I have the same problem.

I found that by removing the control panel, then moving the small red-buttoned switches around the door open switch seemed to solve the problem.

We felt the problem was a mechanical problem because closing the door very gently permitted normal operation.

Turntable operation
I would suggest that you check the door switches and mounts. Here is a file to help: http://www.microwavedisplay.com/doorsw.txt

If those check out, I would suspect a shorted relay or shorted relay-driving transistor.

You may be able to find a schematic of the control unit at the Sears parts site. (They are closed during overnight hours CST)

The best place to order Sharp parts is Tritronics.

Microwave oven inoperative
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
