Drain Switch
All fryer models have a drain microswitch in line with the gas
control valve or heat contactor and the thermostat. When drain
valve is opened to drain the shortening, this causes drain switch
to open, shutting off electrical power to the heating elements.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
1. The following check should be made to determine if the
drain switch is defective. All checks should be made with
drain valve in closed position, with the actuator pushed in.
a. Remove drain switch cover on gas fryers.
b. Remove wires from the switch.
c. Check for continuity across the middle and normally open
terminals on the drain switch. Press on the actuator and if
circuit is open, drain switch is bad. The circuit should only
be opened by releasing the actuator of the drain switch.
Step a
2. To replace the drain switch, remove the two screws
and nuts securing switch.
3. Label and disconnect wires.
4. Connect wires to new drain switch.
5. Position actuator and attach drain switch and switch cover
with two screws and nuts. Tighten nuts to 3 - 4 inch-pounds
of torque.
6. Test to see if drain valve extension rod actuates the switch.
Listen for "click" of switch while rotating drain valve
extension rod.
