KEYPAD STICKING AND STOPS WORKING

Unless there is grease or moisture on the control board, especially in the area where the keypad plugs in, then you would have a failing membrane keypad.

But neither part you would need to repair this is available any longer.

Please feel free to follow up if you have more questions.

It sounds like your membrane keypad may be shorted.

If you'll contact me with the full model number from your tag, I'll give you all the information you would need. In many cases, this is a do-it-yourself repair.

Pressing the Clear/Pause button works. Sometimes. Most of the time, about a microsecond after pressing Clear/Pause, it goes right back to def1. Most of the time, pressing ANY button doesn't work. Usually takes me 10 to 20 tries to get anything to work. My microwave is about 3 months old. I will never buy Emerson again.

Operating functions:
To set the clock, press and hold the clock/timer button for three seconds. A clock icon will appear on the left side of the screen. Input the time using the numerical buttons and then click the clock/timer button to save the time.
To set the timer, press and release the clock/timer button so that the display shows all zeroes. Enter the desired time using the keypad. Press start/stop to start the countdown. The countdown may be paused by pressing the stop/start button and resumed by pressing the same button again.
When countdown is complete, timer will beep continuously for thirty seconds and display will flash. Timer will then beep every ten seconds for ten minutes until the stop/start button is pressed.
This timer will also time up to time activities. To start count up, press clear/memory so timer reads all zeroes. Press stop/start and a plus sign will appear on the right side of the screen as the timer begins counting up.

You have a failing membrane keypad.

To allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and mention that you have a failed keypad.

Sometimes a keypad may not work because the door switches are faulty. When the door switches are working correctly it will allow the keypad to operate. They tell the microwave that the door is closed and the unit is dafe to use.

Many models have 3 door switches, it's wise to get all 3 replaced at once.

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.

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

It sounds like the keypad is worn out. The fact that you can get them to work sometimes by what direction you push on them, tells me that the contacts are not working correctly.

Did you have this problem prior to the fuse blowing or did it start after you replaced the fuse?

I don't believe the fuse blowing is related to the keypad problem. I also don't believe that you have a microprocessor problem because you say that the function buttons work but the number keys don't work right. If the microprocessor was faulty, it would not be able to read any of the keys.

The fact that the number keys are not working doesn't surprise me. When you go to cook something, you will press the number keys several times, while only pressing start or stop once. This is why your number keys have worn out first. These keys have a limited number of cycles (presses) and it sounds like its time for a new keypad.

Please let me know if I can be of further assistance to you.

Good Luck!
