SOLENOID CHECK
To check the Solenoids for power,
hold a screwdriver approximately 1/4”
from the top nut of the Solenoid and
energize the unit. If the Solenoid is
good, it will draw the screwdriver to the
nut through a magnetic force.
To check the valve itself,
remove the Valve Coil from the
Valve Cartridge. Using a paper clip,
push on the Plunger inside the
Valve Cartridge. It should move
freely approximately 1/8”.
Inspect O-Ring and wash the
Cartridge in solvent to remove any
foreign substances inside the
Cartridge. If Plunger still does not
move freely (approx. 1/8”), then
replace the Valve Cartridge.
To check the Motor Solenoid
for power, place a 12 volt test lamp
on the Solenoid Battery Terminal.
