I have often described the sequence on an ice maker, Perhaps I should boiler plate it.. First, far as I know both Dometic and Norcold use U-Line ice makers,, so this is the U-Line sequience
When the ice tray gets cold enough (I think 25F but am not sure) the thermostat closes, the timer motor starts and the gears turn.. As the gear turns a cam closes a switch which bypasses the T-Stat, the U-Shaped heater comes on (With the motor) and a cam raises the wire bail.. The “Fingers” turn down and press against the ice cubes.. When this happens the motor stalls out (normal so don’t worry about it) till the heater melts the ice where it contacts the tray.. Then the motor continues to run and the fingers push the ice cresents out of the tray THe cresents will either fall off the fingers or be scraped off by other fingers…..later
Once the ice is out of the tray a cam closes a switch sending power (Far as I know the full 120 volts) to the solenoid. This switch is adjustable (The screw with teh +/- markings under the front cover) so as to compensate for differing water pressures.
possible issues and solutions:
#1 is TEMP, both Suspect #1 and 1st thing that can go wrong. If it does not get cold enough, it won’t start the cycle. To test, Use a thermometer.
