The bulbs under the microwave for the work space do not work.


On a sharp R-1480, they use a solid state IC on the control board to switch the night/work lights on and off. These IC's can burn up and quit working, or short out and not turn the lights off. I replaced several of these boards close to twenty years ago but I never saw one that was anywhere near close to being a fire hazard. I'm sure that these boards are no longer available.....

Not working


Some of your story seems impossible. Closed doors do not cause anything. Aging capacitors can cause fuses to go. They also stabilize the magnetron. My bet is the capacitor blew. I have no idea why the fan doesn't work, once the cabinet is open it will become obvious.

Microwave door ...hwhen closed....oven light and fan will turn on


This is usually caused by either a bad door switch or a loose door switch mount (which are pretty simple problems to fix).

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

We have uploaded the R1480 service manual to our site here to help you.

If yours is a different model, please reply back.

The best place to order Sharp parts is Tritronics.

I'm having problems with the door switches on my R-1480


We have the R1480-series service manual for this model and have uploaded it to our site here to help you.

You will need the free Adobe Reader to view or print it.

Double-check your wiring against the "pictorial diagram".

The switches will have a "C" (common) terminal, and a "NO" (normally open) terminal, and some will have a "NC" (normally closed) terminal.

As long as those connections are the same and the voltage and current (amps) ratings are the same or higher, any number of switches will work.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

It's easier to secure the switches with hot glue than to replace the latch heads, by the way.
