2-24. DRAIN MICROSWITCH

Sept. 2004
Upon pulling out on drain handle, the microswitch should be
activated and unit will not heat, but when handle is pushed
back, unit should operate properly. The bracket on micro-
switch is slotted so it can be adjusted backward or forward.
1. Remove electrical power supplied to the unit.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. The following check should be made to determine if the
drain switch is defective.
a. Remove bracket from the unit.
b. Remove wires from the switch.
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.
3. To replace switch, remove switch from the bracket, and
install switch in reverse order.
4. Test to see if drain valve handle actuates the switch. The
gap between the drain switch and the shaft should be no
more than 1/8" (3 mm).
HINT: Listen for an audible click of switch while pulling
drain valve handle.
