All fryers are equipped with a drain valve micro-switch that
prevents heat from coming on when the drain valve is open.
With the drain valve open, the switch prevents power from
being applied to the coil of the primary and heat contactors,
and the solenoid coil.
Remove electrical power supplied to the fryer by
unplugging the unit, or turning off the wall circuit
breaker or electrical shock could result.
1. The following check should be made to determine if the
Drain Switch is defective.
a.) Remove the access panel on the right side of the unit.
b.) Remove switch from unit, using 9116" wrench.
c.) Check for continuity across the two outside terminals
on the Drain Switch. If circuit is open, the Drain
Switch is bad. The circuit should only be opened by
pressing on the actuator of the Drain Switch.
2. To replace the Drain Switch, remove the wires from
switch.
3. Connect wires to new rain Switch, and reposition switch
in unit.
4. Test to see if drain valve extension rod actuates the switch.
NOTE - Listen for CLICK of switch while pulling drain
valve extension rod.
