Additional Maintenance: Ice Sensors, Condenser
The ice sensors use a system of infrared emitting
and receiving components to sense the build up of
ice in the bin. They are located at the bottom of
the ice outlet port. They must be free of mineral
build up to function properly. To check:
1. Remove front panels.
2. Push and release the harvest button.
3. Wait for the machine to stop.
4. Remove the evaporator cover.
5. Locate the front ice sensor.
Push the sensor from the front (at the wire area) to
the back until it releases from the holder.
6. Locate the back ice sensor Pull on the
rectangular tab to release it from its mounted
position.
7. Examine the bottom of the brackets, there are
two sensors in each bracket, check that they are
clear of mineral build up. They may be wiped
clean with ice machine cleaner to assist in
removal of the build up.
Note: Do NOT use abrasive materials or cleaner
on the ice sensor lenses. A soft toothbrush works
well to get into the hard to reach spots.
8. Reverse steps 1-6 to reassemble.
To Clean the Remote Air Cooled Condenser
1. Disconnect and lock out the electrical power.
2. At the remote condenser, check for loose debris
on the roof, remove any near the condenser.
3. Check the fan blade and condenser for grease or
dust build up. Brush the intake surfaces (outside) of
the condenser coils with a nylon brush to remove
surface dirt. Use a fin comb to straighten any bent
fins.
Note: ERC611 air flow is UP, towards the fan.
If grease is present, use coil cleaner on the
condenser. Be sure to wipe up any excess coil
cleaner.
4. Reconnect the electrical power.
