My dispenser only works when the left door is slightly open (1 inch ish). I’ve replace the magnetic switch sensors, and the one push sensor. Everything else appears to work properly. I have a Samsung RF28NHEDBSR/AA-00. I’ve removed the top that contains the magnetic switches and put it back, but not clicked in on the left side, and it seems to be working.
Hello, firstly hold the water button for 3 seconds to reset it. See if that works, if not check if you have warrenty with samsung! You can also trouble shoot testing these parts with a multi meter . https://www.repairclinic.com/PartDetail/… , https://www.repairclinic.com/PartDetail/… .
