To troubleshoot a Raynor garage door opener, place new batteries in the remote and check the wiring and the sensor beam. Also, inspect the rollers and door parts to see whether they are functioning properly. In addition, oil the working parts of the door.
If the remote opener is unable to open the garage door, replace its batteries and press any button on the remote to check whether the issue is resolved.
In addition, if the door does not open, inspect the power supply to it. To do this, disconnect and reconnect the supply, and look for any bare or frayed wires. If the cords have exposed wires, cover the bare areas with electrical tape.
For the garage door opener to function properly, the sensor beam must be uninterrupted. To ensure this, check whether the sensors are secured as required. Further, for proper door functioning the rollers and various door parts must be levelled. A door that is not levelled tends to shift from its position. Oiling the door's working parts also ensures its smooth functioning.
If the Raynor garage door opener still does not function, contact Raynor customer service. Alternatively, call a Raynor dealer in your area. Also, check the instruction manual for troubleshooting measures specific to the model.
