A. Check refrigerator compartment thermistor electrical connections and continuity from thermistor to J1
on control board. Reconnect / repair connections.
B. Check resistance of refrigerator compartment thermistor for 30,000 to 33,000 ohms at 0°C (32°F).
Replace if defective.
A. Check refrigerator evaporator thermistor electrical connections and continuity from thermistor to J1 on
control board. Reconnect / repair connections.
B. Check resistance of refrigerator evaporator thermistor for 30,000 to 33,000 ohms at 0°C (32°F).
Replace if defective.
A. Check freezer compartment thermistor electrical connections and continuity from thermistor to J1 on
control board. Reconnect / repair connections.
B. Check resistance of freezer compartment thermistor for 30,000 to 33,000 ohms at 0°C (32°F).
Replace if defective.
A. Check freezer evaporator thermistor electrical connections and continuity from thermistor to J1 on
control board. Reconnect / repair connections.
B. Check resistance of freezer evaporator thermistor for 30,000 to 33,000 ohms at 0°C (32°F). Replace
if defective.
A. With a cold evaporator (< -12°C / < 10°F), initiate Manual Defrost. If compressor starts 5 minutes
after defrost is initiated, check Grey/White wire connections and continuity from defrost heater to J4-4
on control board. Reconnect / repair Grey/White wire &/or electrical connections.
B. Check for proper ohm readings of defrost heater. Replace heater if defective.
C. Check defrost terminator and its electrical connections, Reconnect / repair bad connections or replace
terminator if defective.
D. Initiate Manual Defrost, check for 230 V AC at E2 on control board. If no voltage, replace board.
E. Initiate Manual Defrost, check for 230 V AC from E2 (Blue Wire) on control board to defrost termina-
tor. Reconnect / repair blue wire &/or electrical connections.
F. Reference wiring diagram to identify components in same White wire circuit as defrost heater. Check
all White wire electrical connections and continuity from defrost heater to J7-8 on control board.
A. Check for proper mounting and location of freezer evaporator thermistor and defrost heater. Remount
correctly.
B. Check for correct wire connection at control board, Blue wire at E2 on control board. If connected to
wrong pin, reconnect correctly.
C. Check for electrical short of Blue wire to another circuit. Repair Blue wire &/or electrical connections.
D. Check for proper operation of defrost terminator: Cut-in -1°C (30°F) / Cut-out 21°C (70°F). Replace if
defective.
A. Initiate Manual Defrost. If compressor starts 5 minutes after defrost is initiated, check Grey/White wire
connections and continuity from defrost heater to J4-4 on control board. Reconnect / repair
Grey/White wire &/or electrical connections.
A. Check for proper mounting and location of freezer evaporator thermistor and defrost heater. Remount
correctly.
B. Check for correct wire connection at control board, Blue wire at E2 on control board. If connected to
wrong pin, reconnect correctly.
C. Check for electrical short of Blue wire to another circuit. Repair Blue wire &/or electrical connections.
D. Initiate Manual Defrost. If compressor starts 5 minutes after defrost is initiated, check Grey/White wire
connections and continuity from defrost heater to J4-4 on control board. Reconnect / repair
Grey/White wire &/or electrical connections.
A. Check for proper ohm readings of defrost heater. Replace heater if defective.
B. Check for proper mounting and location of freezer evaporator thermistor and defrost heater. Remount
correctly.
