A. On single solenoid valve, if no voltage -

check wiring and on/off power switch.

B. On dual solenoid valve if no voltage - check

wiring, IGNITION MODULE, and

TEMPERATURE CONTROLLER.

6. If 120VAC is present between two terminals after

performing previous steps, either the solenoid

coil or valve is malfunctioning.

7. To determine if solenoid coil is malfunctioning,

check resistance between both terminals on

solenoid. Readings of 100 ohms or less indicate

a shorted coil. Solenoid needs replaced.
