NM1850R
MAINTENANCE AND CLEANING
The NM1850R is made up of two separate ice makers; to properly clean and maintain the
NM1850R, these steps must be followed for both systems.
/////////////////////////////WARNING///////////////////////////
Disconnect electrical power before beginning.

1. The bin control uses devices that sense
light, therefore they must be kept clean
enough so that they can "see". At least twice a
year, remove the bin control sensors from the
base of the ice chute, and wipe the inside

clean, as illustrated.
2. The ice machine senses water level by a
probe located in the water reservoir. At least
twice a year, the probe should be removed
from the reservoir, and the tip wiped clean of
mineral buildup.
3. The top bearing in the breaker should also
be checked at least two times per year.
Check the breaker bearing by:
• •
removing the ice chute cover
• •
unscrewing the ice sweep
• •
removing the water shed
• •
unscrewing the breaker cover (left hand
thread)
• •
unscrewing the auger stud
