(Continued)
J. Warm Refrigerator
Temperatures without
“SERVICE” Flashing
(See Pointers on previous page)
K. Warm or Normal
Temperatures in Both
Compartments with
“SERVICE” Flashing
Evaporator Fan Fault
a. Switch depressor missing or bent, not
depressing fan switch
b. Fan blade obstructed or out of position
c. Faulty fan switch
(NOTE: A compressor must be running)
d. Evaporator fan motor disconnected
e. Evaporator fan motor defective
(NOTE: Compressor must be running)
Compartment or Evaporator Thermistor
Misread
Evaporator Heavily Frosted
a. Door or drawer ajar
b. Evaporator fan fault
c. Thermistor misread
Power to Compressor Fault
Sealed System Fault
• Sealed System Leak
• Sealed System Restriction
• Inefficient Compressor
High Room Ambient
Condenser Air Flow
a. Dirty condenser
b. Condenser fan blade obstructed or
blade is loose
c. Condenser fan motor disconnected
d. Condenser fan motor defective
e. No power from control board to con-
denser fan (Does not apply to single
compressor models)
(NOTE: A compressor must be running)
Refrigerator Evaporator Thermistor
Disconnected or Shorted
a. Replace/straighten switch depressor.
b. Move obstruction or reposition blade.
c. Check for 115V AC to fan switch, depress
fan switch and check for 115V AC from
switch to motor. Replace switch if defective.
d. Check electrical connections of motor.
Reconnect / repair bad connections.
e. Check for 115V AC at fan motor with fan
switch depressed. Replace motor if defec-
tive.
Check resistance of refrigerator compart-
ment and evaporator thermistors for 30,000
to 33,000 ohms at 32°F (0°C). Replace if
defective.
a. See Door Ajar on previous page.
b. See Evaporator Fan Fault above.
c. See Thermistor Misread above.
Check for 115V AC E6 on control board.
Replace control board if defective.
See Sealed System Diagnostic Tables at
back of Troubleshooting Guide
Instruct customer unit performs best
between 60°F(16°C) and 90°F(32°C).
a. Clean condenser.
b. Remove obstruction or tighten nut on motor
shaft.
c. Check electrical connections from motor to
J7-1 on control board, or from motor to com-
pressor on single compressor models.
Reconnect / repair connections.
d. Check for 115V AC to motor, replace motor
if defective.
e. Check for 115V AC at J7-1 on control board
(with compressor running). Replace board if
defective.
Check for “EE” & “rE” in diagnostic mode.
Check refrigerator evaporator thermistor
electrical connections from thermistor to
control board. Reconnect / repair connec-
tions. Check resistance of refrigerator evap-
orator thermistor for 30,000 to 33,000 ohms
at 32°F (0°C). Replace if defective.
