I have GE JVM1540DN1BB microwawe. It beeps all the time and says "keypad sorted" and service needed. The beep sound is annoying and it beeps every 30 seconds


see this causes and fix it. God bless you
Touchpad and Control Panel If the microwave buttons don't work the touchpad and control panel assembly are probably defective
Touchpad If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Main Control Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Hi!!
Try unplugging the microwave for about 5 min. to reset unit. If problem persists, a new touchpad may needed, check on the following site http://www.repairclinic.com/ for price and availability of the touchpad using the unit's make and model. Some times you'll be better off buying a new unit.

My handle broke completely off - is there replacement handles?


If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

The heat is inop - everything else works on my R-1754 Sharp. Any common problems?


If the fan and turntable are not working when you try to cook, it's likely a bad bottom door switch or mount. See this file.

If the fan and turntable ARE working when you try to cook, the problem is the primary interlock switch, the inverter, the magnetron, or a connection between one or more of them.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

We have the service manual at our site and have uploaded it here to help you.

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.


We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

I have a Sharp model R-1610 Microwave. The work/night light does not work. I"ve changed the bulbs.


Does it operate with a membrane-type touchpad?

These things seem to be problematic as the microwave ages.

They are usually replaceable, and the cost is not great. I just installed a new touchpad on an LG, and it cost $25.00 plus shipping.

R-8350, No power to touchpad, but interior light works


The touchpad has its own fuse which has probably blown due to a surge perhaps related to the turning on of the fridge. Removing the cover from a microwave is potentially lethal due to the large capacitor to drive the magnetron. However, this is usually well away from the front panel. If you do venture in you should first unplug the unit and when the outer cover is removed, discharge the large capacitor with well insulated pliers -= otherwise keep well away from it. The fuse you are interested in is on the pc board behind the touchpad. Replace it with exactly the same fuse (usually a slow blow fuse).
