KHHC2090SSS-2 control panel not working

The control panel on my microwave is possessed. It scans thru screens on its own, and becomes unresponsive to any input. Any ideas how to exorcise this electronic demon?

Our microwave does not consistently come on. When we put in the time to cook it tells us to open/close door. If the cavity light comes on then it works, if not it doesn't work. Please HELP! Thank you


Sounds like you have one or more faulty micro-switches for the door. They are not expensive to get, but your service center will likely charge you a lot to fix it. If you are handy, you can pull the case off and replace them yourself.

I have chefmate microwave and suddenly stopped working. it is showing 2:50 code on the screen only...it was working fine and dont know what happened to it and touch pad is not working..how do i make it...


HELLO.

The code on the screen indicate electric panel fault resulting from the touchpad malfunction.

The touch pad on your microwave oven acts as the brain of the appliance. It not only contains the buttons that you use to enter cooking settings and times, but also controls the function of the entire microwave. If the touch pad malfunctions or breaks completely, the microwave will cease to function. In this instance, the broken touch pad must be removed and a new touch pad must be installed, to restore functionality to the microwave.

1 Unplug the microwave from the wall outlet.
2 Remove the two screws, located on the front or top of the grill at the top of the microwave.
3 Pull the grill off of the microwave.
4 Remove the mounting screw from the top of the control panel.
5 Lift the control panel up and out to loosen. Look behind the control panel to ensure there are no metal tabs securing the control panel in place. If there are metal tabs, gently rotate the control panel to free the tabs.
6 Transfer the wires from the old control panel to the new control panel one at a time to ensure that the wires are properly installed.
7 Install the new control panel into the microwave and secure using the mounting screw that was removed.
8 Replace the grill from the top of the microwave and secure it using the screws that were removed.
9 Plug the microwave back into the wall outlet.
Thanks.

A code of F2 appears on the LED clock timer - not always, but peridically every 30 seconds or so. I unplugged the unit, for 30 seconds, plugged it back in and it worked for about 20 seconds. Then the key...


Hi,

F2 is a bad keyboard error code. Try this, unplug the unit, open the control panel and disconnect the ribbon cable from the control board, plug back in, if f2 comes back on the board needs replacing, if it does not, then the problem is with the keypad.

This is a common problem, and they're often intermittent.

You'll need a new touch screen.

My chefmate 1050 watt microwave beeps nonstop for minutes at a time repeatedly. I must leave it unplugged to get relief. Also, the keypad is unresponsive sometimes.


Either the touchpad or control board is defective. If the ribbon cable was disconnected from the control board and the beeping stops it would confirm the problem. Since the keypad is unresponsive, that probably is the problem.

Touch pad not working properly


That sounds like the interface controller which is just a little computer chip that cotrols everything and watches the signals from the touchpad is having problems. Usually these will behave like this and then just stop so your touchpad is totally dead. It may take out the time displays as well.

If you have warrenty from GE or the store it will be covered. If you are not covered then it can cost about the same or more as a new microwave as they will have to replace the board. Check your warrenty's, then check the repair cost and check replacement costs. Usually a new microwave is the cheapest.
