| Fault characteristic | Remedy |
| The motor cannot be operated | • Check the mains connection. Connect a lamp to the mains electric socket used for the motor. If the lamp lights up, the mains supply is OK. If not, check the fuses. |
| The motor starts, but the door is not opened | • Ensure that the carriage engaged |
| The motor can only be operated pressing button ® but not by the remote control | • Check the battery in the hand transmitter. |
| • Relearn the coding | |
| Insufficient range of remote control (less than 6 m) | • Put the remote control to another place in the car. Point with remote control to the door. Replace battery. |
| The door travels downwards, but it stops before it is fully closed | • Ensure, that the door is in perfect condition as well as greased and balanced carefully. |
| • Check the setting of CLOSE travel limit | |
| • Check the CLOSE automatic cut-out | |
| The door travels upwards, but it stops before it is fully opened | • Ensure, that the door is in perfect condition as well as greased and balanced carefully. |
| • Check the setting of OPEN travel limit | |
| • Check the OPEN automatic cut-out | |
| The door can only be opened | • Check the setting of CLOSE travel limit |
| • Check the CLOSE automatic cut-out | |
| • Check connection or programming of photocell | |
| Noisy operation | • Ensure that all fixings are carefully tightened. Also ensure that the door is in perfect condition as well as greased and balanced carefully. |
| The motor cannot be operated using the wall button | • Check the connections on the connecting terminal of motor |
| • Check the connections to the wall button. | |
| The door moves itself for unknown reasons. | • Disconnect all impulse transmitters (wall button, key switch etc.) from terminal block. Reconnect one impulse transmitter after the other and check it every time by a test run. The door should then start to move. In case the motor operates in one case by itself, check the cabling searching for a faulty contact. If you cannot clearly determin the reason, disconnect the respective impulse transmitter |

| Error | Cause | Solution |
| LED 8 does not light up. | - No voltage. | - Check that the mains power supply is operational. |
| - Check the connection to the mains power supply. | ||
| - Thermal overload protection in power transformer was activated. | - Allow the power transformer to cool down. | |
| - Defective control unit. | - Have the operator system checked. | |
| No reaction on impulse. | - The connection terminals for the "impulse” button were by-passed, e.g. due to a short-circuit or flattened terminals. | - Try temporarily disconnecting any key switches or interior push buttons that are connected to the control unit: remove the cable from socket XB10, insert the shorting plug and look for cabling errors. |

| SITUATION: | CAUSE AND SOLUTION |
| Opener does not operate from either wall control or transmitter: | - Does opener have electric power? Plug a lamp into the electric outlet to see if lamp turns on. If not, check fuse box or circuit breaker (some outlets are controlled by wall switch). |
| - Have you disengaged all locks on door? If not, do so. | |
| - Has snow or ice built up under door? Door may be frozen to ground. Remove any restrictions. | |
| - The garage door spring may be broken. Have it replaced by a professional garage door technician. | |
| Opener operates from transmitter but not from wall control: | - Are wiring connections correct? Check wall control wiring |
| - Is wall control door's Pushbutton lit? If not, disconnect low voltage wires to wall control and momentarily touch them together. If opener runs, replace wall control. If opener does not run, check wiring connections at opener, and check wire for shorts or breaks under staples. | |
| Opener operates from wall control but not transmitter: | - Is the wall control button light flashing? If so, your opener is in the vacation/lock mode. Turn off vacation/lock mode. |
| - Does the transmitter indicator light glow when the transmitter button is pressed? If not, replace battery. | |
| - Has the opener learned the code of the transmitter? Repeat transmitter programming steps. | |
| - Have all transmitters been set with the same code? Repeat code learning procedure for all remote devices. | |
| - Is photo eye obstructed? If so, door will only close while wall control door Pushbutton is pressed and held. | |
| Opener operates from transmitter only from short distance (applies only to 40Mhz models) | - Check antenna wire installation. |
| Door does not open completely: | - Is something obstructing the door? Remove obstructions only after ensuring door area is free of persons, pets, and any other objects. |
| - If door has been working properly but now doesn't open all the way, increase the up force and/or reset the open travel limit. REPEAT "TEST SAFETY REVERSAL” AFTER ADJUSTMENT IS COMPLETE. | |
| Door does not close completely: | - Is something obstructing the door or in the path of the photo eye? Remove obstructions only after ensuring door area is free of persons, pets, and any other objects. |
| - If door has been working properly but now doesn't close all the way, increase the down force and/ or reset the close travel limit. REPEAT "TEST SAFETY REVERSAL” AFTER ADJUST- MENT IS COMPLETE. | |
| Door opens but will not close at all: | - Check the photo eyes for proper connection and alignment. |
| - Increase force in down direction. REPEAT "TEST SAFETY REVERSAL" AFTER ADJUSTMENT IS COMPLETE. | |
| Door reverses for no apparent reason: | - Is something obstructing the door? Pull emergency release knob and open door manually. If it is unbalanced or broken, call for professional garage door service. |
| - Clear ice or snow from garage floor area where garage door closes. | |
| - Review and increase force adjustment setting for down travel. | |
| - If door reverses from fully closed position, decrease travel limits. | |
| - REPEAT "TEST SAFETY REVERSAL" AFTER ADJUSTMENT IS COMPLETE. | |
| Opener light does not turn on: | - Replace the light bulb(s)—maximum 60 watts each. Use a "garage door opener light bulb" if regular type bulb burns out prematurely. |
| Opener light does not turn off: | - Is the wall control Light Feature on? Press Light Button to turn off. (applies only to Elite 2007 models) |
| Opener strains or maxi- mum force is needed to operate door: | - Door may be out of balance or springs are broken. Close the door and use emergency release knob to disconnect trolley. Open and close door manually. A properly balanced door will hold itself halfway open while being supported entirely by its springs. If it does not, disconnect the opener and call for professional garage door service. DO NOT increase the force to the opener to compensate for unbalanced or damaged door. |
| Opener does not move door at all: | - Door may be locked with a manual door lock. Remove any manual door locks. |
| - Springs are broken or door is out of balance. | |
| Opener won't work due to power failure: | - Use the emergency release knob to disconnect trolley. Door can be opened and closed manually. When power is restored, reconnect trolley and resume automatic operation of door. |
