Question about Microwave Ovens

2 Answers


My microwave has the code A-1 in the display and sometimes when it feels like it, it'll beep and go to A-2 and A-3 and back again. I can't do anything with it. The keypad won't accept anything and I've plugged and unplugged and even tried differnt outlets and still the same problem. Is it time for a new microwave? hotpoint RVM1625 microwave has a F3 code and it will not let me do anything.

F3 would be a shorted keypad. This is not too hard a job for the do-it-yourselfer.

I have a sumsung SMH9151s microwave that recently started having problems. Now it keeps beeping and in the display its going back and forth to the letter L and back to 0. I tried unplugging it and plugging...

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link:

Microwave keeps beeping on GE spacesaver JVM1640WB

Does the display say anything?

If it says "F3" then you have a shorted keypad.

Please post a new question with full model number and more detailed symptoms.

New unit used 3 days. Microwave beeps and screen goes to menu, or set time screen. Sometimes changes the date all by itself. Does this in the middle of the night all night long.

I advice you to contact service if it has guarantee. This seems to be a psychological problem about your oven(!). Technical person need to do an electronic research surgery on its board to see if there is any wrong thing.

Samsung microwave displays press 1-4...

The SE indicates a short in the keypad membrane, but to cure this! the whole keypad control board should be changed if effort to resolve is decided, I would also suggest checking the pricing.

LG Microwave Beeps 3 times, display shows F3 and keypad dead.

Since it's less than one year old, it would be fully covered under warranty.

I'd suggest returning it to the dealer or contacting the manufacturer to get it fixed free.

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.

I couldn't find those exact trouble codes, but a common problem is when the controller gets damp, either from steam rising from the cooktop or someone spraying cleaner directly on the keypad. Cleaners should always be sprayed on a soft cloth, then wipe the keypad with the cloth. Also, GE / Samsung codes of F1, F2 and F3 may be the same since Samsung makes GE microwaves. Those would mean trouble with the temperature sensor, keypad, or control panel. Assuming your control panel is clean and dry, it may be time to call for service.
