RV Microwave Not Working

When we plugged in our rv for the first time this spring, the microwave made a series of beeps and then the keypad stopped working. The display reads 0 and the light inside comes on when the door is open. Any suggestions for a fix?

I tried looking up the part number for this model and they don't identify clearly what the touch pad is. Would have to get one of the parts companys (andrewselectronics.com) to do research on it.
I've done surgery on a few touch panels and it usually works out. Have to break through the plastic tabs holding it together, then you can clean the contacts. Then do something like find little tiny screws to fasten it back together.
Hope Ya Fix It!

Chances are if the internal fuse and magnetron thermostat are good, then you have a circuit board that needs repair.

You can probably find exploded views at the Sears parts site. If you find a bad thermostat, the best place to order Sharp parts is Tritronics.

We regularly repair these control panels for customers nationwide (RV owners & dealers, too) with our guaranteed $39.95 service.

Feel free to contact me directly for more information & help.

I had the EXACT same symptoms with my Sylvania SR1109sb after a power surge.
After some digging around I thought what the heck let me try holding down the Reset button and do a power off/on cycle and what do you know it worked !!!
Just pressing the Reset did nothing until the cycle off and on.

Sharp Carousel Microwave Mdl 1875 for our RV is dead


>> We also tried plugging our toaster into the microwave plug outlet, and the toaster wouldn't work in that outlet, but worked just fine in a different outlet in the RV.

This means the outlet you plug your microwave into needs to be fixed in addition to fixing the oven. Breaker? Fuse?

>> I understand from another RV forum that microwave ovens for RVs have "special circuitry and cooling features" not found in regular countertop ovens for household use.

Not really in my experience. Any microwave supplied with clean AC power and proper venting space will be fine.

But I'd bet your microwave can be fixed affordably.

The main internal things which can result in this model being dead (no display, no light when you open the door, no beep when you press a pad on the keypad) would be the 20A fuse and the magnetron temperature fuse. There could also be bad connections on the noise filter board.

Also, sometimes a power surge can cause the power to be interrupted to the low voltage transformer on the board, and I regularly repair those boards. I can also write a technical statement to your insurance company or to an RV park as needed.

At my Web site, I have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

The relevant service manuals for this model are here and here.

You can order Sharp parts from Sears or Encompass.

Contact me directly if you need more help.

The problem is in the keypad control board, eventually it will need to be replaced, also there may be a intermittent short in the keypad membrane this is where a professional will be needed to make that determination.

Microwave beeps, error codes display and keypad stops working


It sound like you have a bad keypad or controls.

Is it possible that moisture from the sponge is getting into the controls?

You might contact the manufacturer to see if there might be a recall. I've seen keypad recalls in the past.

Anytime the keypad is suspected of coming on by itself, the oven should be unplugged when not in use.

Microwave oven will not work


Seems like I've answered this before, but the MR5493G is subject to a recall due to defective keypad (membrane switch) and can be seriously dangerous.

See: www.allworldauto.com/recalls/samsung_microwave_mr5493g_recalls_1420-10455-1.html

The MR1032BB is also under recall. See: www.motorbeat.com/model/samsung+microwave/mr1032bb/

If neither is covered under the recall, you should be able to order new keypads here: http://www.samsungparts.com/search/search.asp

If not, we'd be happy to help you. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk
