This site is great. I got the service manual to put mine into defrost mode. I have actual temperature settings, but I set freezer to 5, but can't set the frig side lower than 34. Anyway, held all four buttons, got blinking zeroes, and set 1 and 4 to go into manual defrost and hit a button to start and away it went, I hope.
Is this an older model that has the actual temp on front?
