Have an appointment tomorrow morning with customer with this fridge and is not defrosting.
APP's diagram shows a defrost timer & defrost control on diagram but only the control on parts list.
Repair Clinic shows both in parts list.
The control board is not available any more. Does anyone happen to know if this unit has a mechanical or control board? If it's a control board issue I don't want to charge the customer to say I can't get the part pay me when I already know I can't get it. I will call before and let them make the decision just wondering if anyone know's.
