Centrifugal Switch
Checking heater/gas valve and motor:
1.Disconnect the wire harness from the motor.
2.Place ohm meter leads to terminals 1 and 2.
3.With your thumbs, depress the BROWN disc located behind the motor switch on the motor shaft. The BROWN disc actuates the lever of the motor switch when the motor is at rest. At optimum motor speed, the disc moves away from the switch lever. When the disc is pressed in toward the windings, the actuator arm of the centrifugal switch will be relaxed. This allows the contacts to close, completing the heater circuit. If no continuity is found when the disc is depressed, change the centrifugal switch.

Motor Test Cord
A motor test cord may be used to electrically check operation of the various electrical components without removing them from the unit. Testing in this manner determines whether or not the part will function independently of other electrical components. In order to make an accurate test, proper connection of the motor test cord is important.
Drive Motor Test
The motor may be checked in the dryer or removed and checked.
Air Shutter Adjustment
The air shutter has been stamped "LP" and "N" (for Natural). Loosen the screw holding the shutter, rotate the shutter until the end of the slot (labeled for the gas to be used) contacts the screw. Tighten the screw to lock the shutter in place.
Two test leads are required to check operation of the drive motor. To check the motor for operation, hook the test cord to terminals 4 and 5.
