Check for 24 VAC between "G" and

"C." Check all wiring connections.

Make sure that the thermostat

connection plug is securely

connected.

Loose wiring

Check all wiring connections at motor

and control box. Check that power

and control harnesses are securely

connected.

Interface

board

problem

Make sure that the interface board is

not damaged and that all DIP switches

are in the proper configuration (refer

to the blower performance tables).

Faulty motor

Check supply voltage to the motor.

Check that all motor wires are secure.

Move the "TEST" DIP switch to "ON"

and the other switches to "OFF" on

the "ADJUST" switch block on the

interface board—the motor should run

at 70% torque when "G" is called. With

power off spin the motor shaft—noise,

resistance or uneven motion can be

signs of motor failure.

Faulty

solenoid

Check that the reversing valve

solenoid is receiving 24 VAC.

If it is receiving 24 VAC, check the

resistance of the solenoid—an open

circuit may indicate a burned out

solenoid.

Miswired/

faulty

thermostat

Check that the reversing valve

thermostat wire is connected to the

“O” terminal of the thermostat.

Check for a contact closure between

“O” and “R.”

Loose wire

on “O”

terminal

Check that the wires from the

thermostat to the unit are securely

connected and that the wires from the

electrical box to the reversing valve

are connected.
