Question about Samsung MW5592W Microwave Oven

Open Question

Samsung MR5491G display prompts to touch a keypad function, but nothing happens with any punched button. The display = "2 Touch a functrion key..." etc This display was self generated. It was set to display the time-of-day. When I looked at it a day ago, it displayed "2222". After reset power I got the above display. Keypad seems to be locked out. I have had this unit start cooking all by itself.

Your keypad or control board may have moisture or grease on them, but your keypad (membrane switch) is likely going bad. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find a keypad (if available) by entering your exact model here: http://www.samsungparts.com/search/search.asp

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

You can order Samsung parts here.

You can find your nearest Samsung-authorized service center here.

To find out if yours was recalled, please call Samsung's Service Division at 800-932-3837.

I have the same "SE" problem. After reading this thread here, I realise it's likely the keypad problem, which explains the microwave's behaviour (no key was working).

So there were two possibilities. (1)keypad failure and (2) bad connection.

Obviously the easiest thing I could start with is to clean the connection. So I first take the cover off. Behind the keypad is a circuit board. In addition to a few connections between the circuit board and other parts of the microwave, there is a ribbon connecting the keypad to the circuit board.

Loose the plastic on the connection, pull the ribbon out from the socket. I then used spirit to clean the exposed copper connections. Put every thing back to place.

Voila, it's working again and we have been living happily ever after.....

The top quick access buttons stopped working 2 days ago. The bottom buttons still work but, we can't punch in a custom time. The only thing that will work is the 1 for 1 minute 2 for 2 minute...etc.


One of two things is happening, either you have broken connections in the membrane switches of the keypad and should replace the keypad(which is most likely) or your main control board has failed in a way that it can no longer read signals sent by the keypad.

My MMV5165BAW displays *** with micro, AM/PM, help..etc under each x. Display flashes this msg. Touch pad will not work, but when it displays to set the clock, touch pad will work. After setting clock


There may be grease or moisture on the the control circuit board, especially in the are where the keypad strip plugs into the board.

Or there may be a pad stuck on th keypad.

See the owner's manual here in case that might help you.

Otherwise, the controller assembly may need repair, which is usually economical.

I have a samsung microwave in our motorome. the power is on and I get the "Samsung 50 simple" indicator. However there is no response to the touchpad. The owner's manual says...


You have a bad keypad if you cant get it to respond at all.its also possible the door is not latched properly but usually the clock will set with the door open or closed so I doubt that is the issue
The display is actually saying "Samsung So Simple".

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

I touch the touch pad and nothing happens


Hi!!
Try unplugging unit from the wall outlet for 5 min. If the key pad still do not respond, it may have become defective they are not fixable. Replacing the key pad it is often more expensive then buying a new unit.
Spills and directly spraying cleaner solutions into keypad will eventually cause it to fail.
The correct way to clean the front of your microwave is to apply a small amount of the cleaner solution to a cleaning cloth and then wipe the keypad clean

F2 E0 "Stuck key" ????????????


F2-E0 - Shorted Touch Pad (Keypad) - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure.
Select the 'cancel' function and wait 60 seconds.

You have a faulty keypad. You could probably special order this part from a local appliance parts supply store for 50-60$ or purchase a new microwave.

Your Control Key Pad is a circuit with each function and button a switch. The pad on your TV Remote, and Telephone is no different. The Key Pad is failing, It will only get worse. Determine if you can replace the Touch (Key) Pad. Not the Control Circuit, just the Touch Pad. Sometimes you can get it seperate. It connects by a Flex Cable to the Control Circuit.
