Troubleshooting #1

“MOTOR RUNS BUT RUBBER DRIVE WHEEL DOES NOT PULL DRAPERY CORD”

Likely problem: Broke Drive Axle

Likely cause: A broken Drive Axle indicates that your motor is out of adjustment, and has repeatedly over-traveled the limits of your drapery track.  In other words, the motor has kept running for several seconds or minutes after your drapery reached its travel limit.  The Drive Axle has a safety feature that is designed to break in extreme conditions.  If the axle broke, it prevented the breaking of your drapery cord, or other damage.  This feature is similar to a shear pin in an outboard motor propeller that breaks to sacrifice itself if it hits a log or rock; it prevents other damage.  A broken drive axle is not a defect.  It did the job it was designed to do.

What to do: 

  1. Order replacement Drive Axle P/N 29008.

  2. ALSO: Inspect BOTH cord tension pins molded in the Front Body on either side of the Rubber Drive Wheel.  If any pin is broken, also order Front Body P/N 29003.

  3. ALSO: You can avoid future damage by following this procedure. Before installing motor, OPEN drapery HALFWAY, After installing motor, or ANYTIME drapery stops closing fully, make BOTH of the following adjustments soon as possible.

  • Set motor to STOP when drapery is fully closed with no over-travel.

  • Set motor to STOP four (4) inches or more BEFORE full open. ALWAYS set motor to STOP four (4) inches or more BEFORE full open.


Troubleshooting #2

“MOTOR RUNS BUT MAKES SCREECHING or grinding NOISE”

Likely problem: One or more gears inside motor transmission stripped.

Likely cause: Same as example #1 above.

A screeching motor indicates a damaged gear, most likely Motor Shaft Gear.  The Motor Shaft Gear is another safety feature that can prevent damage to your drapery if motor goes out of adjustment.  In extreme over-travels conditions, it will slip on the motor shaft to dissipate motor torque.  In the process, it can become damaged and require replacement.  

What to do: 
1. Order replacement Gearmotor P/N 46555. 

  • If any other gears are damaged, even a single gear, replace entire Gear motor P/N 46555 so issues wont continue.


Troubleshooting #3

“MOTOR KEEPS RUNNING AND WILL NOT SHUT-OFF”

Example: The black dial actuators on front of motor do not rotate when motor runs.  

Test: You can freely rotate the black dials with your fingers without resistance.  

Likely problem:  Broken gear-mounting post inside housing.  

Likely cause: Same as examples #1 and #2 above.

What to do:
Disassemble motor to inspect Front Cover area (do not open motor transmission case).  When you open the Front Cover, if a black gear falls out or is loose, that is the problem.  Order replacement Front Cover Assembly P/N 29077.  This part includes white Front Housing with pre-installed black Actuator Dial System and black gear. 


Troubleshooting # 4

“MOTOR DOES NOT RUN”

Likely problem:  AC-DC Adapter failure, or control switch failure (timer or remote control).

Test as follows: 

  1. Unplug AC-DC Adapter from timer or remote control switch.

  2. Plug Adapter directly into electric outlet.  If motor runs immediately, motor and Adapter are OK, but timer or remote control caused the problem.  If motor does not run, Adapter might have failed.

  3. Use voltage tester to measure Adapter output.  Output should be 12 volts DC or more.

  4. You can also test motor using a different AC-DC Adapter that you might have plugged into something else.  CAUTION: First read test Adapter label. Verify its output is 12 volts DC (never AC).

What to do:

Order replacement AC-DC Adapter P/N 78950.

Troubleshooting # 5

“MOTOR ONLY RUNS 1 DIRECTION”

Likely Problem: CIRCUIT BOARD MIGHT HAVE FAILED.

What to do: 

  1. Following instructions above to verify timer is set properly. 

  2. Test: Unplug AC-DC Adapter from your timer.  Plug Adapter directly into AC outlet.  Motor should run.  Unplug Adapter, wait for 3 seconds, plug in again.  Motor should reverse direction.  Repeat.  Adapter and motor circuit board are OK. 

IF MOTOR FAILS TO RUN AS STATED ABOVE, ORDER REPLACEMENT CIRCUIT BOARD P/N 65001
