A. Check the liquid line valve relay.
The relay is on the circuit board, if it does not supply power to the liquid line valve, the
valve will not open.
1. Check for power at the valve coil, if none:
a. Check for power at the liquid line valve relay at the circuit board.
If there is power at the relay, but none at the liquid line valve coil,
Check for an open wire between the relay and the valve.
2. Check the valve coil. If the coil is open, replace the liquid line valve.
3. Check the auger drive motor centrifugal switch. If, when the drive motor is running,
contact 4 (black wire removed) has no power, and all of the above switches have been
checked, replace the centrifugal switch, or the drive motor.
4. If the liquid line valve relay on the circuit board has power on the NO contact, but not on the COM
contact, replace the circuit board.
