PROBLEM
POSSIBLE CAUSE
TEST / ACTION
(Continued)
AA.
Warm Freezer Temp. in
BF/I-2 without “SERVICE”
Flashing
(See Pointers on previous page)
Evaporator Fan Fault
a. Fan blade obstructed or out of position
b. Evaporator fan assembly out of position
c. Evaporator. fan motor disconnected
d. Evaporator fan motor defective
(
NOTE:
Compressor must be running)
(
NOTE 2:
After a defrost, the evapora-
tor fan will not run if evaporator is below
35°F)
e. Faulty Reed Switch
(
NOTE
Compressor must be running.)
Compartment Thermistor Misread
Evaporator Heavily Frosted
a. Drawer ajar
b. Evaporator fan fault
c. Compartment thermistor misread
d. Defrost heater disconnected or faulty
e. Defrost terminator disconnected or
faulty.
f. Drain tube heater disconnected or
defective
g. No power from control board to defrost
circuit
Power to Compressor Fault
Sealed System Fault
•
Sealed System Leak
•
Sealed System Restriction
•
Inefficient Compressor
a. Move obstruction or reposition blade.
b. Make sure evaporator fan assembly is in
grooves of fan shroud and there is no play
from front to back. Reposition if out of posi-
tion.
c. Check electrical connections from motor to
P9 on control board. Reconnect / repair
bad connections.
d. Check for 115V AC at fan motor with Reed
Switch depressed. Replace motor if defec-
tive.
e. Check for 24V AC from P2 on control board
to Reed Switch, depress switch and check
for 24V AC from Reed Switch. Replace
Reed Switch if defective.
(
NOTE:
there are
two Reed Switches)
Check resistance of freezer compartment
thermistor in Reed Switch for 30,000 to
33,000 ohms at 32°F. Replace Reed Switch
if defective.
a. See Drawer Ajar on previous page.
b. See Evaporator Fan Fault above.
c. See Thermistor Misread above.
d. Check heater electrical connections.
Reconnect / repair bad connections. Check
resistance of heater, 25-29 Ohms, replace if
defective.
e. Check terminator electrical connections,
Reconnect / repair bad connections or
replace terminator if defective.
f. Check drain heater electrical connections.
Reconnect / repair bad connections. Check
resistance of drain heater, 1700-2100 Ohms,
replace if defective.
g. Manually initiate defrost by pressing ICE key
for 10 seconds. Check for 115V AC at P8 on
control board. Replace control board if
defective.
Check for 115V AC at P14 on control board.
Replace control board if defective.
See Sealed System Troubleshooting Guide
Low Voltage Circuit.
Do NOT apply 115V AC.
