Models 390XX.XXX. It controls the fan motor.

The relay has a 24 volt AC coil. To check the relay, first

verify all AC volts have been turned off to the unit.

Next, remove the wires from COM and NC terminals.

Verify the relay coil is not energized (no AC power).

Continuity should exist between terminals COM and NO.

Next, energize the relay coil with 24 volts AC. Continuity

should exist between terminals COM and NO and no

continuity between COM and NC. If the above checks are

correct, the relay is good – DO NOT replace it. If the above

checks are not correct, the relay is defective and should be

replaced.

It controls HIGH FAN and LOW FAN on Circuit 1 and 2. If

this relay is not wired correctly, Circuit 1 fan will not operate

with Circuit 1 compressor.

The relay has a 120 volt AC coil. To check the relay, first

verify all AC volts have been turned off to the unit.

Next remove the wires from terminals 2, 4, 6 and 8. Verify

the coil (terminals 0 and 1) are not energized (no AC

power). Continuity should not exist between terminals 2 to

4 or terminals 6 to 8. Next, energize the coil (terminals 0

and 1). Continuity should exist between terminals 2 to 4

and terminals 6 to 8. If the above checks are correct, the

relay is good DO NOT replace it. If the checks are not

correct, the relay is defective – replace it.
