Problem
Possible Cause
Remedy
[1] The icemaker will not
start (continued).
f) Gear Motor Internal
Overload (Thermal
Protector)
1. Open.
1. Allow to cool and reset.
Check gear motor
bearings, auger bearings
(see "V.C.1. Upper Bearing
Wear Check"), and
supply voltage. Check for
evaporator freeze-up.
g) Optional Drain Pump
HS-0248 Safety
1. Open.
1. Check drain pump. See
"IV.D. Optional Drain Pump
HS-0248."
[2] Gear motor starts,
but compressor will
not start or operates
intermittently.
a) Power Supply
1. Not within
specifications.
1. Refer to nameplate and
correct.
b) Compressor Relay
1. Open coil.
1. Replace.
2. Open contacts.
2. Replace.
c) PTC Relay
1. Bad contacts.
1. Check for continuity and
replace.
2. Coil winding open.
2. Replace.
3. Loose connections.
3. Tighten.
d) External Compressor
Overload (Thermal
Protector)
1. Open due to clogged
condenser coil.
1. Clean condenser coil.
2. Open due to
condenser fan not
operating.
2. Check condenser fan for
continuity and replace.
3. Defective.
3. Let compressor cool and
allow overload to reset.
If overload does not reset,
replace overload.
e) Compressor
1. Wiring to compressor. 1. Check for loose
connection or open, and
tighten or replace.
2. Motor winding opened
or grounded.
2. Replace compressor.
3. Compressor locked.
3. Replace compressor.
[3] Compressor starts,
but gear motor will
not start.
a) Gear Motor
1. Bad gear motor
capacitor.
1. Replace capacitor.
2. Open windings.
2. Replace gear motor.
3. Locked bearings
3. Replace gear motor.
[4] Gear motor and
compressor start, but
no ice is produced.
a) Water Supply
1. Water supply off or
pressure too low.
(suction temperature
safety cycling open
and closed)
1. Check water supply, filters,
water inlet strainer-washer,
float, and water valve. Get
recommended pressure
(7 to 113 PSIG).
