Electronic Functional Description

WARNING

To avoid electrical shock which can cause severe personal injury or death, disconnect power to refrigerator using power switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure correct earthing and polarization. After servicing, reconnect power using power switch.

Refrigeration and Defrost Component Checks Made at High Voltage Board

Low voltage board input		W1 to D11		approximately		-25 VDC
High voltage board input	E10 to E9 (Neutral) or ground		approximately		120 VAC
Compressor/condenser fan motor		“ON” = E4 to E9 (Neutral) ground		approximately		120 VAC
		“OFF”= E4 to E9 (Neutral) or ground
Compressor/condenser fan motor		“CLOSED” = R7 to ground		approximately		-11 VDC
relay“OPEN” = R7 to ground		approximately		-25 VDC
Evaporator fan motor relay		“CLOSED” = R8 to ground		approximately		-11 VDC
		“OPEN” = R8 to ground				-25 VDC
Evaporator fan motor		“ON” = E2 to E9 (Neutral) or ground		approximately		120 VAC
		“OFF” = E2 to E9 (Neutral) or ground				0 VAC
Defrost heater		“ON” = E6 to E9 (Neutral) or ground		approximately		120 VAC
		“OFF” = E6 to E9 (Neutral) or ground				0 VAC
Defrost heater relay		“CLOSED” = R9 to ground		approximately		-11 VDC
		“OPEN” = R9 to ground		approximately		-25 VDC
Defrost terminator		“CLOSED” = E5 to E9 (Neutral) or ground		approximately		120 VAC
		“OPEN” = E5 to E9 (Neutral) or ground				0 VAC
Fresh food fan output voltage		“ON” = E1 to ground		approximately		-25 VDC
High voltage board to fresh food fan		“OFF” = E1 to ground				0 VDC
Fresh food fan input voltage		“ON” = R10 to ground		approximately		-11 VDC
Signal to high voltage board from
low voltage board		“OFF” = R10 to ground		approximately		-25 VDC

Filament voltage at pins 11 and 12 = less than 5 VAC
