WATER LEVEL CONTROL CIRCUITRY
FUNCTION
The water level probe controls the water level by
sensing whether water is or is not contacting the water
level probe. The water level probe has three sensing
probes. Two probes are equal in length and are used
to measures conductivity for diagnostics, ice clarity
and water miser options. Factory default settings
measure resistance from both long probes to the short
probe.
SPECIFICATIONS
Freeze Cycle Water Level Setting
During the Freeze cycle, the water level probe is set to
maintain the proper water level above the water pump
housing. The water level is not adjustable. If the water
level is incorrect, check the water level probe position.
Reposition or clean the probe as necessary.
Water Inlet Valve Safety Shut-Off
In the event of a water level probe failure, this feature
limits the water inlet valve to 12.5 minutes. Regardless
of the water level probe input, the control board
automatically shuts off the water inlet valve if it
remains on for 12.5 continuous minutes (30 seconds
in prechill and two 6 minute periods in the freeze
cycle).
