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 measure
conductivity for diagnostics. Factory default settings
measure resistance from both long probes to the short
probe.
SPECIFICATIONS
Freeze Cycle Water Level Setting
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 maximum amount of time the water inlet valve
can remain.
SINGLE EVAPORATOR MODELS
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).
Initial cycle is 14 minutes and 12.5 minutes thereafter.
DUAL EVAPORATOR MODELS
Regardless of the water level probe input, the control
board automatically shuts off the water inlet valve if it
remains on for 16.5 continuous minutes (30 seconds in
prechill and two 8 minute periods in the freeze cycle).
Initial cycle is 18 minutes and 16.5 minutes thereafter.
