1. Disconnect wires from timer, except timer motor
wires.
NOTE: Refer to appropriate wiring diagram
when rewiring timer.
2. Manually rotate timer out of “OFF” position and
into cycle.
3. Set test motor to read Ohms. The following
readings should be found:
a. Motor circuit test – L1 and M = “zero” Ohms
(closed)
b. Heat circuit test – L1 and H = “zero” Ohms
(closed)
c. Timer motor test – L1 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
NOTE: Rotate timer to “cooldown” (5 minutes
before “OFF”). “Infinite” (open) reading should
be found between L1 and H.
d. Rotate timer to “OFF” position. “Infinite”
(open) reading should be found between L1
and M and between L1 and H.
NOTE: Timer motor power is supplied through M
