TEST / ACTION
Check resistance of compartment thermistor
for 30,000 to 33,000 ohms at 0°C (32°F).
Replace if defective.
1. Change temperature units of measure to
Fahrenheit. Switch unit OFF, then ON, then
press & hold Bell key and UNIT ON/OFF
key for 10 seconds.
2. If Outside US - Change temperature units of
measure to Celsius. Switch unit OFF, then
ON, then press & hold Bell key and UNIT

Check position of fill cup. Reposition if in
ice path.
•
Check water supply pressure; must be con-
stant 20-100 PSI. If not, instruct customer.
•
Check water valve operation, opens when
230V AC is applied, closes completely when
230V AC is removed. Water valve Ohms =
160. Replace if defective.
NOTE:
Unit must be switched OFF, then ON to
clear flashing ICE & SERVICE, then press
alarm key for 15 seconds to clear error
codes.
Connect/turn on water supply.
Freezer must be -8°C (17°F) for icemaker to

installation. Instruct customer.
See PROBLEM A, B, D, E, F & G earlier in
Troubleshooting Guide.
Check shut-off arm, if stuck in up/off posi-
tion, correct problem.
Check electrical connections and water con-
nections at water valve, Reconnect / repair
connections.
Check resistance of water valve, 160 ohms.
Replace if defective.
a. Check water supply pressure for "constant"
20-100 PSI. If not, instruct customer.
b. Check electrical connections at fill tube
heater. Reconnect / repair connections.
Check resistance of fill tube heater.
Replace if defective.
c. Initiate manual defrost and check for 230 V
AC from control board. Replace board if
