Question about Microwave Ovens

Problem with the display

I own a SHARP Microwave - Model - R-307NW. I bought it just 3 months back. One fine day, cockroaches started accumulating in the LCD panel. I tried to tap it and shoo it off.. No, it was not going. So I thought of removing the back cover and trying to clean it myself. I read in the websites about the capacitor danger and tried to be very careful. I managed to remove all the screws, including the anti-tamper ones. Then I removed the LCD panel also from the unit. Since the problem was only in the LCD unit, I didnt bother to remove all the wires.
Then while trying to remove the LCD.. its just gave off.. and the wire from the touch pad to the LCD came off. Now the glass in the LCD was in my hand without being connected to the touch pad. After cleaning it.. I tried to put it back the same way it was before. When I switched ON.. it was displaying - "88:88" blinking. But the touch pad was not working.
I disconnected it again and tried to put things in place.. But nothing worked out. Yesterday while checking it again, the "black and white small foam like pad" also came off from the LCD glass. Now the "88:88" display is also gone.
Can you please help me with what exactly is the issue with it. And is it really worth to get it repaired in Sears or elsewhere? What would be the cost of the part to be replaced? Please advise.

    The solution was good, but it didnt help me since the rubber connector broke off and cleaning didnt help. I couldnt get the required part from Encompass. So I finally bought a new microwave oven.

I've checked, and cannot seem to find online service data on this model. Perhaps it's too new.

But it sounds like you have one which has the glass LCD and keypad connected to the circuit board via a zebra strip type "rubber connector". This is what you referred to as the "black and white small foam like pad". It is called the rubber connector.

It's similar to the model shown in the attached exploded view and it shows you what to clean.

If cleaning doesn't work, you need to order the LCD glass and the rubber connector.

You will probably have to call Tritronics with your model number to get these parts. They are toll-free at 866-779-5835.

Remvoe the panel and see if there is any infestataion of cockroaches or insects into the display panel. if so remove and clean the bord properly using some petrol and a brush. make sure you do not damage the display or the board. Now check for any dry solder on the printed board , if bad do a touch up solder on the suspected dry points. check for the filter capacitors of the power supply and the regulators.
Check votage to the mP , solder the crystal and check.

Sharp microwave 1200 watts keypad showing

Not a complete answer, but may help describe problem: Our R-510B should be the same except for color, and for several years it has intermittently messed up its display. The left side two segments on the units digit won't light up. So a digit 8, without the two vertical bars on the left, comes out as a letter E reversed left to right. Any digit that uses the two left segments (traditionally labelled segments E and F when talking about 7-segment displays) comes out wrong. Every thing else works fine. I can't tell if this is your problem.
This is almost surely a bad contact at the interface between the LCD display panel and the PC board: Typically there is a "squishy" conductive strip that connects them, and I expect grease has gotten in there. If so careful disassembly and cleaning with a mild solvent should fix it. Since we can live with it, and it usually fixes itself in a few weeks, I have not got around to taking it apart.

Re: Sharp carousel microwave oven minute display light out

Hello there
To replace the light you will first have to remove the outer shell.
To do this
(1). Remove all of the screws on the back of the microwave that hold on the shell
(2) Remove the screws that are on the bottom.

(3) now the shell should slide off towards the back of the microvave.
Note : this may take a little bit of pressure to get it off ok?

(4) Once the cover is off look towards the fromt of the microwave and
you will see the bulb. now just replace the bulb and reinsert the cover and the screws and you are all done ok? pretty easy ha/
best regards michael

Jenn-Air Microwave M169B 11 years old.

You should be able to get a replacement keypad, and that's not a hard job for a DIYer.

If you're interested, post your correct brand and model and I'll give you a more specific suggestion.

(Your post subject says Jenn-Air M169B put it's posted under Sharp R-316FS so I'm not sure which you have).

If it's a Jenn-Air, you can usually find helpful exploded view diagrams and order parts by entering your full model number here:
