COMPONENT TESTING

COOLING FAN MOTOR
COOLING
FAN MOTOR
TERMINALS
NOTES:
1. FAN RATING IS 120 VAC, 60 HZ, 2.5-WATTS.
WARNING
Electrical Shock Hazard
Disconnect from electrical supply before ser-
vicing unit.
Failure to do so could result in electrical
shock or other personal injury.
Test Procedure
Refer to page 4-16 for the location of the
cooling fan motor and the procedure for ser-
vicing it.
To test the cooling fan motor windings, per-
form the following steps:
1. Use an ohmmeter and set the range switch
to R x 1.
2. With no power applied, touch the leads of
the ohmmeter to the terminals of the fan
motor (you do not have to remove the wires
from the terminals). You should obtain a
reading of between 55 Ω and 80 Ω.
If the reading is not within the range shown,
the motor is defective and should be replaced.
ELEMENT CONTROL
(INFINITE SWITCH)
WARNING
Electrical Shock Hazard
Disconnect from electrical supply before ser-
vicing unit.
Failure to do so could result in electrical
shock or other personal injury.
Test Procedure
Refer to page 4-4 for the location of the ele-
ment controls and the procedure for servicing
them.
To test a control, perform the following steps:
1. Use an ohmmeter and set the range switch
to R x 1.
2. With no power applied, touch the leads of
the ohmmeter to the indicated terminals of
the element control (infinite switch). You
should obtain the following readings:
Control OFF:
L1 to P = no continuity
L1 to H1 = no continuity
P to H1 = no continuity
L2 to H2 = continuity
Control to HI:
L1 to P = continuity
L1 to H1 = continuity
P to H1 = continuity
L2 to H2 = continuity
If the readings are not as shown, the control is
defective and should be replaced.
