a. Disconnect wires from timer, except timer
motor wires.
NOTE: Refer to appropriate wiring diagram when
rewiring timer.
b. Manually rotate timer out of “OFF” position
and into cycle.
c. Set test meter to read Ohms. The following
readings should be found:
(1) Motor circuit test – L1 and M = “zero”
Ohms (closed)
(2) Heat circuit test – L2 and H = “zero” Ohms
(closed)
(3) Timer motor test – T and N =
approximately 2460-3100 Ohms or apply
live power to timer motor terminals and
motor should run.
NOTE: Timer Motor Resistance:
120 Volt, 60 Hz 2,460 – 3,100 Ohms
240 Volt 10,900 – 13,000 Ohms
24 Volt 80 – 130 Ohms
(4) Rotate timer to “cooldown” (5 minutes
before “OFF”). “Infinite” (open) reading
