What is the model number of your microwave oven?


790.80353310 Kenmore microwave



What happens if you remove the power, leave it off for about 5-10 minutes and then reconnect the power? Does it reset to normal or do you get the same error message again?

Apologies if you have already tried this.


When the error E-11 shows up I turn the breaker off over night and turn it back on the next morning. Once I program the time the microwave works again. The error shows up when I am cooking and the microwave fan is on. As soon as the error shows up the microwave keypad does not work anymore. I am assuming the steam that comes off the stove while I am cooking gets into the microwave control panel and shuts it done with the E-11 error.

If it doesn't occur when you are using the microwave oven and not the stovetop then from your description it seems that the humidity sensor may be faulty. ( Part # 28 click on Oven Cabinet) or perhaps it is doing what it was designed to do and protect the microwave in times of high humidity. If it only just started doing this and you have mostly always at some time had steam rising from the stove in the past then perhaps it may have become more "sensitive" and has at least not gone completely faulty and stopped you from using the microwave altogether.

Given the cost of the part and the lack of any information that I can find regarding fault codes, I am loathe to suggest that you find out if this is the case by ordering a new part. You may wish to contact Sears regarding their Returns/Cancellations policy as it might allow you to test the new part (before you install it) to check if it has the same "reading" as the old, which you will obviously have to remove first.

Removing it to test using an Ohmmeter (I don't know what the normal reading should be) might also not be too easy as it seems to be a difficult part to replace as the "degree of difficulty" in the repair is quite high (according to the part information page.

my microwave is say e-11, if i press a button it wont do anyyhing.... why?


Hi @lauren_ordyne9 ,

Try turning off and disconnecting the power to the microwave oven for about 10 minutes and then reconnecting and turning it on again to see if it now works OK.

It may be that the humidity sensor in the microwave has operated and has stopped the microwave from working to prevent any damage from occurring to it.

Once it resets hopefully the oven will work again.

It's a safety feature to prevent damage to the oven due to high humidity (steam)
