Solenoid Valve
This is an electromechanical device that causes pressure to be
held in the frypot. The solenoid valve closes at the beginning of
the cook cycle and is opened automatically by the timer at the end
of the cook cycle. If this valve should become dirty or the teflon
seat nicked, pressure will not build up. The solenoid valve used
on all models is the same with the exception of the coil. The gas
model fryer uses a 120 volt, 60 Hz, coil. The electric model fryer
uses a 208/240 volt 60 Hz coil. The 440/480 volt electric model
uses a transformer to drop voltage to 220/240 volts.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
Coil Check Procedure
1. Remove the cover of the junction box in the rear of the fryer.
Locate the solenoid wires and remove them from the wire-
nuts. Check the ohms of the solenoid coil by checking
across the solenoid wires. Use chart below:
