Recently had to replace the delay kit on our ice maker door dispenser. Today, the ice maker dispenser won't stop when we take the glass away. The chute door closes like it is supposed to. Finally, just had to leave the freezer door open for a while. We are afraid to touch it. Could you help tell me what part I need to get now. I hate to spend too much on this frig since it is so old. Has been a great one, though.
