You probably have a failed membrane keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

But please note that for some 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.

Either way, we can let you know what your options and costs would be and send you other helpful info.

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.

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.

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

The control panel of my sharp grill 2 convection microwave oven is very dim


Hi,
Dimmed light might be caused by a slight contact between the panel's connector and the mainboard. Or, there is a dimmer option (feature) in the menu. Depends on model. Some of Panasonic microwave ovens are equipped with such a feature.
Regards,
Dan

If you have access to where your microwave is plugged in, unplug it for a few minutes and then plug it back in. This will reset your contol panel. Then follow your book directions to reset the time on the clock. Hope this helps!

This an old range with side by side ovens which work perfectly. the 4 burners slide out, all 4 elements will heat, but do not get to a high heat, is there a control which affects all of the elements ...


Hi and welcome to FixYa, I am Kelly.

This sounds like your missing 1/2 of your input power. Go to the main CB panel and cycle the Range CB to OFF by pressing it hard to off and then back on. Test your burners again.

Still have the problem? Start looking in the area of the house to oven power connection / terminal block in the back of the oven for signs of HOT / burned terminals.

Still have the problem... Last check is to check wiring in the main controls area.

Without your model number this a VERY generic response but when all burners present the same symptom it is usually input power or control related.

If you respond with a model number I wil see what I can find that may help you troubleshoot your Oven.

Thank for choosing FixYa,
Kelly

Non-responsive samsung microwave (mw1030wa)


You have a failed membrane keypad.

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.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

On this model, we could do that job for you for $79.90, but that may not be economical when compared to a replacement unit.

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.

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

Sharp R-505FS Control pad has stopped working over several days. Pressing numbers gets no response. Every few days more numbers or functions ceased to work.


Hmmm... that model number is not showing up. Wonder if it was made for a market other than the US or something?

I'd be happy to help you if I could. Could you check that model?

Kenmore microwave model number 401.80084700 Displaying -SE-/-5E-


-SE- error means you have a shorted membrane keypad.

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.

There are three ways you can get it fixed:

DE34-00178X SWITCH MEMBRANE $20.30
ref#53 membrane keypad
take yours off as in the video at our site, peel the old keypad off as in this handy guide with pictures , clean the surface, stick on the new keypad
order by part number here
(We can do this job for you for a total of $70.25, but as you can see, the other two options are more practical and economical)

DE94-01647A ASY CONTROL PANEL $39.01
ref#66 control panel frame with keypad
take yours off as in the video at our site, disconnect the keypad strip as shown here, move your circuit board to the new frame, reinstall
order by part number here

DE94-01648A ASY CONTROL, BOX $58.12
ref#59 complete control panel assembly with frame, keypad and circuit board
take yours off as in the video at our site, then install the new one
order by part number here

If these parts are not in stock, they should be available in about a week or so.

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

Tricky touch pad on Sharp R530 es microwave oven


There are two options here:

1. Order a new control panel frame which has the keypad, trim piece and door button already installed and swap your control boards into it.

The original part number FPNLCB346MRK0 has been replaced by part # FPNLCB346MRK0B and it runs $58.28 plus shipping.

2. Disassemble your control panel frame, peel off the old keypad and stick a new one on.

Even though the keypad alone runs only $35.66, this job takes a lot of time and labor.

If you (or someone you know) might want to replace just the keypad yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

Whichever option you choose, we have the service manual for this model and have uploaded it to our site here to help you.

You will need the
free Acrobat Reader to view or print it in case you don't have it already.

Froze and is non-responsive


If it will not CLEAR, You can try Un-Plugging it from the wall, let it dis-charge for 10min., then try . If you still have the problem, I would think your Control Panel has failed. The Control Panel is like an Electronic Controlled Switch with Pre-Programmed sections and Timers. Replacement is the only option. Sorry!

My microwave is locked


It would help if you could reply with the model number, but we'll give a preliminary response now...

Many modern Sharp models have a Custom Help button you can press, and one of the options in that menu is the Child Lock, which you can turn on or off.

Just check the options if yours has a Help or Custom Help pad.

If that doesn't solve it, please do post back with your model number. We're happy to help you.
