OVERLOAD GUIDE ELECTRICAL
High or low voltage weak power lines can cause overloads on icemaker restarts High running current. Check motor circuits and start relay – Auger delay failed.
ICEMAKER
Mechanical parts worn. Scored evaporator or auger. Worn thrust bearing. Ice maker not turning off. Failed ice level control.
Over compression. Low water inlet temperature. Restriction in water line from reservoir.
REFRIGERANT
Contaminated charge or bad compressor. Low charge or gas leak.
Low suction pressure. Improper expansion valve sensing bulb. Location or insulation and/or defective expansion valve
