Troubleshooting

The shade does not roll up straight (coning)

Some shades have a tendency to cone on the tube to one side or the other when being rolled up. A common indication of this problem is a shade that slows and stops before reaching the top stopping point. In the photos, notice how the fabric on the shade is encroaching the wheel in the picture on the left. While the picture on the right shows the shade is pulling away from the wheel.

To fix this, unroll the shade until you can see where the fabric is attached to the roller, apply a small piece of masking tape (three or four inches) on the tube on the opposite end from where the shade is coning. Release the shade and let it travel to the top. Hopefully, this will have corrected your problem. A second or even third piece can be applied to fix more extreme coning issues.

Troubleshooting Procedure for Manual Shades

Flat blade screwdriver needed. Push in adjuster with the screwdriver before adjusting.

Shades Retracting Too Fast / Slow Spring Adjuster Color Black

  • Locate the black adjustment wheel for the shade in question.
  • Turning the adjuster counter-clockwise will reduce spring tension.
  • Turning the adjuster wheel clockwise will increase spring tension.

Shades Stopping Too High / Low AutoStop™ Adjuster Color Gray / White

  • Locate the Gray/white adjuster for the shade in question.
  • If the shade is stopping too low you will turn the adjuster counter clockwise.
  • If the shade is stopping too high you will turn the adjuster clockwise.
    *Always test the shade by pulling it down and releasing it after any adjustment to be sure it is working properly.

Troubleshooting Procedure for Switch Controlled Motors

  1. Verify power is applied to the motor by pressing the rocker switch either up or down. (Voltage should be between 11.0 and 13.6 volts DC.) If the voltage is low, charge the chassis/coach batteries and retry shade operation. Voltage can be verified at the rocker switch or in the disconnect/butt splices in the motor wiring leads. Verify positive and negative voltage (both up and down directions) from the switch.
  2. If the motor fails to move, press and hold the learning button and rocker switch for about 4 seconds. The motor will give a series of rapid beeps. Release the rocker switch and the learning wires. If the shade beeped, proceed with the directions “Switch Motor Shade Limit Adjustment.”
  3. If the motor has power but still fails to move in either direction after following Step 2, please contact MCD for assistance.

Troubleshooting Procedure for Remote Controlled Motors

  1. Verify the voltage applied to the motor. Voltage should be between 11.0 and 13.6 volts DC. The positive wire is Red, the negative wire is Black. If the voltage is low, charge the chassis or coach batteries and retry the motor operation. Voltage can be verified in the disconnect/butt splices in the shade motor wiring leads. Verify positive and negative voltage from the switch.
  2. If the shade fails to move, attempt to reset the motor by pressing and holding the learning button for four jogs then release. If the motor does not jog, verify that the power is going to the motor. If power for the shade is not present, correct the power problem.
  3. Refer to the 2-Channel or 15-Channel programming guide to link the shade motor to your remote controller.
  4. If a shade motor fails to link to the remote controller, try to use a spare channel on your 15-Channel or 2-Channel remote controller. If the motor links to the remote controller on an alternate channel, please contact MCD for assistance.
  5. If the motor will not program to any channel on any remote controller, the batteries have been replaced, and correct voltage has been verified, please contact MCD for assistance.
