Replaced faulty micro switch with new OEM switch. Plastic pins that held the spacer and switch in place broke off when removing the old switch, probably because the fridge was about 10 yrs old and the plastic was brittle. Super glued the pins back on and installed a new switch. Put face plate back on the door and done. The dispenser is working fine again. Appliance repairman estimated $200 to fix- I did it for $26 and change including shipping.
