It may be the latch head spring or the door open lever or button.

DOOR SPRING LATCH HEAD HOOK


If you gently push up on the door latch heads (hook-like devices sticking out of the door) there should be spring tension. If they just flop right up, the spring is off inside.

Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

you have to separate the door panels (as shown in the attached photo) and then you'll see how it goes together.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

DOOR OPENING BUTTON LEVER

What usually breaks is the door open lever, but it may also be that the rear side of the door open button has worn down too far to work.

On a counter top model, the outer cover will need to be removed to diagnose and repair this. On an over-the-range model, only the control panel needs to be removed.

Please unplug the oven first.

Once it is apart, you'll be able to see how the door open button would press against the door open lever, which would then lift up against the door latch heads (hook-like projections on the door) and the door should open.

You can usually find exploded views and part numbers for Sharp models by entering your model number at the Sears parts site.

If not, let me know. We have many Sharp manuals and if we have yours, we can link you to it at no charge.

The best place to order Sharp parts is
Encompass (formerly Tritronics).

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

I am familiar with TV sets being stuck in demo mode, but I've never heard of a microwave doing this. The fix for this on a TV is usually pushing a combination of buttons at the same time.

Call Sears or Best Buy and talk to an appliance salesman, or call a repair service. They surely wouldn't charge you anything for giving out this info.

HAD SAME ISSUE 6 YEARS AGO.

ITS A MAJOR PART AND ITS NOT SAFE IN THAT STATE.

IT JUST SLIPS MY MIND AS TO WHAT IT IS CALLED.

UNPLUG IT.

CALL A REPAIR SHOP.

TELL THEM WHAT HAPPENED, TELL THEM TO QUOTE A PRICE.

KEEP IN MIND THAT A NEW MICROWAVE IS PRETTY CHEAP THESE DAYS.

GOOD LUCK.

no, glues are no good in microwaves due to high temperatures, may give off toxic fumes etc. you need new door fittings which isnt easy to fit, take to approved dealer, he will also test for leakage out side the door.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

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.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions (similar to these) are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it's not shorted, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html
(even if the magnetron passes these tests, it can still be bad. If you have high voltage and the diode is good, assume the magnetron is bad)

You would have to remove it from the wall to replace the magnetron, take off the outside cover, discharge the capacitor, then disconnect the magnetron's wires and mounting nuts.

We have the service manual for this model and have uploaded it for you here.

(Our site is down as I write this, but rest assured it is there.)

You can order parts for this brand from Encompass here or you can call them toll-free at 866-779-5835.

Most manufacturers can offer a "drop-in" replacement if you tell them your model number. Call Sharp toll free at 1-800-BE-SHARP (1-800-237-4277).

Your machine is probably burned up by now ... but I will try to help you.

I suspect your door safety interlock switches are selded in the closed position. Remove the cover and look on the right hand side for these small switches. Unplug the device and be mindful there is 25,000 or more volts waiting to get you in the silver thing to the back side. Check the switches with a ohm meter. There is a common terminal, a normally open terminal and a normally closed terminal. My guess is one or both switches are going to read closed (short)

buy another microwave !!!!! its gonna be sooooo much cheaper

Sharp R-1480... | Answered on Sep 05, 2009


It sounds like the latch or strike is loose. Try to tighten it up. You may have to replace the switch if it is damaged.

It can be oiled with something akin to Pam (cooking oil spray). You don't want petroleum products in your oven -- it'd take forever to get the fumes out.

I'd try first just spraying some under the turntable as far back toward the center as you can get it -- run oven -- spray some more, etc., etc.

Replacing the inside light will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download Whirlpool owner's manuals and installation instructions here.

To help with step-by-step disassembly, we have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

You can also find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

That sounds like a door switch. Which switch is it? Top, middle, bottom?

Is your model number R1480? If not, please reply back with your model number so we can help you.

The door switches in model R1480 are:

QSW-MA110WRE0 top & bottom switches

FFS-BA016/KIT middle monitor switch with fuse (kit)

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

But the best place to order Sharp parts is Tritronics.

If none of this info helps you, please reply back with your brand and model number and let me know which part you need.
