SOURCE: Amana ARGS7650 Keypad has no power

I had the same problem, same model. The electronic panel has to be replaced. This part is ~$215 before tax and shipping. With labor, I was looking at over $400. I bought a 4 yr old used GE gas oven for $75. That was my solution.

I believe the part to replace is labeled Erciii, gas

Part Number: AP4041311 made by WHIRLPOOL
This would have taken at least a week to ship (no one seems to have them in stock).

From now on, I will never own a range in which the oven or stovetop controls are electronic. Knobs and associated mechanics can be replaced MUCH more easily and cheaply!

My Frigidaire ffmv162lw Microwave just shows "0:05" on the display and no buttons work.


You have a shorting membrane keypad. And you are correct - if and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking, especially if it's doing this!

The details of my answer assume that your model number (from the tag on the microwave, not the manual) is FFMV162LWA (white). If not, please let me know.

On these models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

You can order part number 5304477374 from the Sears Parts Direct Web site for $98.65 (prices subject to change).

There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then detach the keypad connector as shown in the photo below, and then remove the control panel screws.

Be careful not to crack the glass display when handling it, or it's a goner.

Reassembly is the reverse of disassembly.

I have sharp microwave oven model R-231F. On digital display (which is suppose to show time) only 88888 is displayed. suspect fault with the PCB behind display or keypad. Please advise how I can obtain...


First I would suggest a "hard reset". Simply unplug the oven for a minute or two, then try again.

If it still fails, it may be that the keypad has failed, or there is a bad connection due to moisture, grease, etc.

This is an Australian model, so it's hard for me to give more specific information.

But one some US models the LCD and keypad connect to the circuit board via a rubber "zebra strip" and losing that connection can result in a loss of display segments and / or key response.

I've attached a diagram showing where one can clean to restore operation in this case.

How do you replace the touchpad on a sharp


If one or more of the keys are not responding when you press them, it may need a new keypad, or it may just be that the connections need cleaning.

On some of these models, the display and keypad are connected to the circuit board via a conductive rubber zebra strip.

Sometimes steam (or spray cleaners!) can get in there and interfere with conductivity for the keys and/or display.

One would have to take it apart and clean the connections with high-grade alcohol, like 70% or better isopropyl from the drug store.

The attached photo is similar but not the same model.

If the keypad has been damaged or a cleaning does not do it, you will need a new keypad, and disassembly can be a bit tricky.

You can find links to helpful exploded view diagrams and part ordering help here.

I'd recommend that your bookmark this link to your favorites.

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.

If you decide to send yours in for repair, here is the info you need:

We have a service / repair manual for a similar model and have uploaded it to our site here to help you.

It should be similar enough to give you safety info and similar step by step help in disassembly info.

Most computers will open this document automatically, but you may need the free Adobe Reader.

We would really need the front door panel assembly (which contains the keypad, display board and connecting cable) as well as the power board to which the cable connects, as shown in the attached sample photos.

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.

Sharp Carousel Model R9H84B


I've attached the portion of the manual which shows how to lock & unlock this model.

If that doesn't work, unplug the oven for one minute, plug it back in aga9in, then try again.

If it still doesn;t work, then your keypad has failed, and they are no longer available for these model, so the oven would have to be retired.

Good luck.

Microwave Keypad not working


This model does have a child lock. If it's on, the display will say "LOCKED". It is turned on and off by holding dfown the "0" key for 4-5 seconds. You may also have a bad keypad, which in many cases can be replaced. A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Repost if you need more help.
