KitchenAid #KEMS308GSS1 combo microwave/wall oven

11 posts in this topic

The keypad has failed after I removed the unit to replace the bulb.  Error codes F2- E0/E1.

I cleaned the ribbon but still no response.  I am assuming I need to replace the keypad and not the control unit, but prior to spending $300+, is there any way to verify that the problem is definitely the keypad and not the control unit?

Thanks

SRB

What did you use to clean the Ribbon Cable ?

Are you sure the Ribbon cable is in all the way ?

Do any of the Keys work ?

I cleaned the ribbon with a red pencil eraser then q-tip with alcohol

I am sure the ribbon is inserted all the way, probably put it in and out a dozen times.  It has small tabs to align it correctly and than a locking collar, so all seems to be well there.

I have no response at all from the keypad. 

Could the ribbon itself be the problem, or where it is connected to the keypad?

Thanks

Hello SRB and the gods of appliantology please help me, I just had the same problem as SRB.

My KitchenAid Superba Microwave oven combo (model: KEMS307GBS0, serial: XJ2401083) displays error F2, e1, and keypads are not responding very well (erratically).

I changed the dead microwave bulb according to the procedures smoothly (and damned sure that I turned off the power during the change steps).

I cleaned the keypad ribbons also as suggested by the sifu in Eureka, but still dsiplays F2, e1 error after a couple of minutes - microwave seems to work warming foods/drinks, before F2, e1.

If I toggle the switches and sensor (F2 e1 means lock sensor/solenoid problem in manual) on the oven airvent, then the error display got reset as if, but will end up with F2 e1 display error again.

To SRB, what did you end up doing to fix your unit? Please share your valuable solution/experience with me, cuz I had exact same problem as you did.

Is there any other thing I should try before raising my white flag? - wife will not be happy about trying my skill to replace the stupid bulb.

The tech. sheet for your unit shows the F2 E1 being the keypad just like the previous poster

matter of fact the same tech sheet I believe.

Thats a great question, I can only assume that he replaced the keypad.

If I can find additional info. I will post it.

Tinkerdude,

Sorry for your aggravation, this unit is a piece of $%@#. I did end up replacing the front control panel ($), crazy money for just replacing a bulb!!!!. Just not quite sure why the ribbon is so sensitive. Once replaced, it works fine with the exception of I can't use the convection oven on the microwave. Don't know why, but we are just living without. It starts and runs for about a minute then fails. Oh well.

I cleaned as everyone has said, with an erasure and q-tip and alcohol. I did this 3-4 times and reassembled each time, just never worked. I just hope this bulb lasts longer than the last, I don't want to go through that again.

FYI I'm sure you have had to replace the front tension springs on the microwave door. I've done at least 5-6 times now. Horrible design. I have found a simple way to do this where it only takes about 5 minutes and you only have to pop off the door, and not pull the unit out. Open the Lower Oven door and drill a small hole large enough for a screw driver to fit through the flat vent on the left side under the microwave door. Make sure to line it up carefully with the phillips head screw on the bottom of the microwave door. When removing, remove the 4 screws inside the micro door (hold on to the door), then remove the lower vent. then you can remove the screws at the bottom of the door by opening the lower oven door. once this is done, you have full access to the tension springs without having to pull the unit out.

Thanks SRB, so you replaced the control panel that has the keypads, or control board (with electronic components)?

If the control panel, where did you buy your replacement control panel? I checked the black color has been discontinued by the manufacturer - it's nightmarish.
