Small Appliance Repair Questions? Ask a Technician ASAP
Hello and welcome to just answer my name is ***** ***** I will be the one to assist you. So it sounds like the problem is with either the control board.
This is the part for your unit you will need to replace. I hope you find this information helpful and would be willing to rate with 5 stars at the top so I am credited for my time Rating does not stop you from getting back to me in the event you need me.
My apologies I had meant to remove that I had though possibly the speed board but remembered you said in your original question that the speed works fine. So that would not be the problem.
