COMPONENT TESTING
Before testing any of the components, perform
the following checks:
The most common cause for control failure
is corrosion on connectors. Therefore, dis-
connecting and reconnecting wires will be
necessary throughout test procedures.
All tests/checks should be made with a
VOM or DVM having a sensitivity of 20,000
ohms-per-volt DC, or greater. •

Refer to page 4-5 for the procedure for ac-
cessing the louver motor.
1. Unplug air conditioner or disconnect power.
2. Disconnect the louver motor connector
from the control board.
3. Insert a small test wire into pin 1 of the
louver motor connector.
4. Insert a small test wire into each of the
remaining pins (2 - 5) in sequence to test
the motor windings.
5. Set the ohmmeter to the R x 1 scale.
6. Clip the ohmmeter test leads to the test
wires. The meter should indicate between
190 and 210 Ω for each of the windings.

Check all connections before replacing
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
Resistance checks must be made with
power cord unplugged from outlet, and
with wiring harness or connectors discon-
nected. •
