How To Troubleshoot A Malfunctioned Garage Door Opener Remote
Posted on: 27 June 2017
A malfunctioned garage door remote can be an inconvenience, especially when it is raining, and you have to manually open the door. Garage door remotes may be a convenience, but the advanced technology means more things can go wrong with them.
Garage door openers operate by transmitting a signal to the wall switch, which triggers the motor to open the door. It is usually easy to troubleshoot a garage door opener by following these tips.
Replace the Batteries
Many problems with remotes, such as the remote not opening from a distance, usually can be traced to the battery. Ensure the remote is plugged in, and check for blown fuses or tripped breakers. Replace the battery with a standard name brand battery.
Rechargeable batteries may be cost-effective, but they only produce 1.2 volts as opposed to 1.5 volts on a standard battery, which makes a difference in power going to the remote. Use a Phillips screwdriver to detach the cover screws, remove the old battery, clean the contacts with a cotton swab, and insert the new battery. Clean battery contacts produce better signals.
If a new battery still doesn't help, visit your neighbors, because the button on their remote could be stuck. A stuck button on a neighbor's remote could cause interference.
Adjust the Safety Sensors
If your remote only works properly in cold or hot weather, the safety sensors, or photo eyes, that run on the bottom of the door may need adjusting. To verify it is an issue with the sensors in the weather, press the wall switch to cancel the safety feature. If the door opens, then the issue is most likely the sensors. Use the screwdriver to loosen the screws to adjust the sensors.
The steel housing may expand and contract in extreme climates, causing distortion of the signal path. During cold weather, the sensors may fog in heated garages. When this happens, use a soft, damp rag to clean them. The slightest beam misalignment may trigger the safety feature once the temperature changes. If you still have a problem, disconnect the power cord and reconnect it.
Reset the Remote
If all else fails, try to reset the remote. Look for the "LEARN" button on the back of the remote opener motor, which is close to the adjustment screws. Hold the button down until the light flashes. Remove the batteries, leave them out for thirty seconds, then reinsert them.
Replace remotes with damaged lights or battery contacts. If nothing seems to work, contact a garage door service. Click here for more about this topic.
