DANGER
DO NOT service the unit until the main
electrical power has been disconnected.
Cause
a. No electrical power to the unit.
b. Rocker switch set incorrectly.
c. Drain tube is kinked or
obstructed.
d. Bad pump. Diagnose by
bypassing the pump. Pull both
pink wires from control board
and jump the two terminals
together. If unit starts up, then t
he pump is bad.
a. No power to unit.
a. Bad bin thermostat.
b. Bin thermostat set incorrectly.
a. No water supplied to unit.
b. Stand pipe not inserted in water
trough.
c. Re-circulating pump is defective.
a. High ambient temperatures
around unit.
b. Deposit build-up on evaporator
grid.
c. Ice thickness dial set incorrectly.
d. Dirty condenser coil.
Correction
a. Make sure unit is plugged in and
outlet has power.
b. Check switch wiring. Set to “ICE.”
c. Clear the tubing. If water cannot
drain from pump, unit will shut
down due to safety design of
pump.
d. Change pump. Jumping the two
terminals together on the control
board with a jumper wire will
eliminate pump from the circuit.
a. Jumper plug off power cord.
Remedy
a. Replace bin thermostat. The unit
is falsely sensing a full bin.
b. Set bin thermostat at the 10:00
position.
Remedy
a. Check that water is connected
and turned on.
b. Insert stand pipe securely into
water trough.
c. Replace re-circulating pump.
Remedy
a. Lower ice rate is normal with high
ambient temperatures.
b. Run the unit through a clean
cycle. Use only Electrolux Ice
Machine Cleaner.
c. Adjust ice thickness dial
accordingly.
d. Clean condenser coil.
Remedy
NOTE: Light on control board will indicate if condenser is too dirty. A rapid flash of light indicates high
heat conditions which could be caused by either an inadequate air flow or a dirty condenser.
