Question about Microwave Ovens
I have a Sharp R530 countertop microwave. The display panel had gone partially blank a few years back, but the unit continued to operate normally.
Then a few weeks ago, after a power outage, the display magically returned to normal, but the unit started acting up. While operating, the timer would continue to count down, but the unit would stop working for a few seconds (turntable would stop, fan would stop and presumably magentron too). Then after a few seconds, everything would come back on..
Then yesterday, the same thing happened, but it didn't start back up again. Now the display continues to work, but othere than the interior light, nothing happens inside the microwave.
Is this something that can be fixed with a display panel rebuild or is it more serious?
Do you wast a lot of time tring to buy a part for a Sharp product I have all outlets including the manufacture web site or by phone are useless try these guys on this web site they know what they are talking ..Norm

We have the R530ES service manual for this model and have uploaded it to our site here to help you. It's close enough to the R530EK and EW models, in case that's what yours is.
You will need the free Acrobat Reader to view or print it.
Actually you have two separate problems, and both are easily solved..
(1) The reason that only the inside light comes on when you try to cook is that your secondary (bottom) door interlock switch is bad, or its mount is misaligned or broken.
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.
If you only need a switch, you can order one from us for $5 postpaid or local appliance parts stores, hardware stores, or places like Wal-Mart, Lowe's or Builder's Square.
(2) The display problem is something we regularly repair these for customers nationwide with our guaranteed $39.95 service in about a week.
