I`m afraid that the control board it in need of replacing .
When you turn the power off and back on ,you are reseting the control .
This parts link is for part number and price reference only,, you can purchase the part at any local Appliance parts dealer in your area.
And yes it is one of the more expensive parts !
I appreciate confirmation of my own research. I would like to know if it is something I can replace once I get the part. I am searching for information regarding this now.
oh yes if you are handy it only takes basic hand tools .
Just remember to unplug the unit before doing any work on the unit .
and thank you for rating me too!
I ordered the non-returnable part and now the microwave key pad is working just fine. Is it possible the problem was something else. If it is a computer, I do not see how it fixed itself.
have you opened the box that the part came in ?
the control is only held in place with four screws and very easy to replace.
