Switch related problems:
• If room moves opposite from what the switch plate indicates,
reverse the motor wires on the back of the switch
(refer to the wiring diagram page 12). Wire size must be 10ga.
Min.
• If a gear is stripped, the entire gearbox must be replaced.

TROUBLESHOOTING – POWER UNIT
Before attempting to troubleshoot the PowerUnit, make sure an adequate power
source is available. The unit batteries should be fully charged or the unit should
be plugged into to A/C service with batteries installed. Do not attempt to
troubleshoot the Power Unit without assuring a full 12V DC charge
The following tests require only a DC voltmeter (or DC test light) and a jumper
lead.
Step 1 - Attach voltmeter (or test light) leads to the negative and positive switch
terminals on back of wall switch (See Fig. 11). Does the meter indicate 12V DC?
If YES, see Step 2; if NO see Step 3.
Step 2 - If YES, at the motor, check the incoming leads to 12V DC (if necessary,
disconnect leads at wire splices). Does meter indicate 12V DC? If YES, Power
Unit needs to be replaced. The motor is not field serviceable. DO NOT
ATTEMPT TO REPAIR. If NO, Inspect all wires and connections bewtween the
wall switch and the motor. Repair connections as necessary. Recheck as in
Step 1.
Step 3 - If NO, Inspect all connections between battery and switch. Inspect 30A
Circuit Breaker (See Fig. 11). Recheck as above in Step 1.
Since there are no field serviceable parts in the motor of the Power Unit,
electrical troubleshooting and service is limited to replacing only those
components as previously outlined.
Thorough inspection of wiring and connections is the only other electrical service
that can be performed.
