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 panel.
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: 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.
