I went to this one and the evaporator fan wasn't running. It was showing me an "E" in the freezer display and an "F" in the ff display. I'm thinking freezer fan error I saw that it was a 12 volt dc fan but I wasn't seeing any voltage to it. I unplugged it to look at some wires and when I plugged it back in, the code was gone and the fan came on.This is a side by side with the control mounted under the fridge. The owner told me over the phone that it was doing exactly that before he replaced the board and fan himself, a board he found on Amazon. Then it would only run for a day and then the EF code would come back.
I am thinking he got a bad board but I have no experience with this type of unit. Is there something else I should be looking at to find the problem?
