Question about Sharp 2.0 cu.ft. 1200 Watt Microwave - R-530EKT Black 13.375"H x 24"W x 19.125"D

1 Answer

Microwaves fan and light on permanently

FAN RUNS AND LIGHT STAY ON AS SOON AS IT IS SWITCHED ON AT THE MAINS. AND ONLY SWITCHING OFF AT THE MAINS STOPS IT. OPENING AND CLOSING OF DOOR DOES NOTHING..COOKING OF FOOD ISNT AFFECTED BY THIS.

One of the relays is stuck. Hit it firmly and see if the fan turns off

SOURCE: Over the range microwave

I have the R-1460 in the same series with the identical symptoms. After reading MicrowaveSvc's solution I started taking apart to view the door switches and found the upper door switch to be the problem, but not a switch failure a support failure. A small bottom plastic support post that holds the switch in place was broken (probably from repeated use/abuse) allowing the switch to move when the door hooks were engaged, thus not actuating the button switch. Since the problem was mechanical rather than an electrical bad switch, I made a small support arm for the switch from an old plastic mechanical pencil and glued it in place to hold the switch in its correct position. Problem solved, microwave works! Thanks to MicrowaveSvc's description of door switches.

SOURCE: 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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Fan runs when door is closed and no time set.


Some GE units were starting on their own. I would definitely unplug this oven and call GE to make sure yours wasn't one of the ones being re-called.

The 13amp fuse blew in the socket and when replaced the light and fan worked in the oven however no heat was produced...any help would be greatly recived the oven is a newhomes el616.


Door switches

If one of the door interlock switches is not switching properly or there is a condensation problem on the sensor control panel, either can cause the turntable/light/oven to come on even though the "Start" button has not been depressed due to the wiring of the switches or it can take the mains power fuse out and stay faulty.
Check for faulty door switches and/or contaminated actuators.

Alternatively, the magnetron, supply or HV diodes can fail and take the mains fuse out.
I hope that helps.

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Exhaust fan


Is the light on?
Things that it could be.
Could be a door switch.
Or it could be a stuck fan relay
Or worst odf all it could be a bad Timmer Keypad board. Not worth fixing because they cost to much.
