If your electric garage door opener keeps tripping its built-in Ground Fault Circuit Interrupter (GFCI) outlet without any apparent exposure to water or moisture, there could be a few potential causes for this issue. Here are some possibilities to consider:
Faulty GFCI outlet: The GFCI outlet itself might be faulty or malfunctioning. Over time, these outlets can wear out or become sensitive, causing them to trip more easily. Consider replacing the GFCI outlet to see if that resolves the problem.
Wiring issues: Faulty or damaged wiring can cause a GFCI outlet to trip. Check the wiring connections of the outlet, as well as the wiring leading to the garage door opener. Look for any loose connections, frayed wires, or signs of damage. If you notice any issues, it's advisable to consult a qualified electrician to inspect and repair the wiring.
Overloading the circuit: The garage door opener may be drawing excessive power, causing the GFCI outlet to trip. This could occur if the opener is connected to a circuit that is already near or at its maximum capacity. Try unplugging any other devices or appliances that are on the same circuit and see if the problem persists. If the circuit is overloaded, you may need to redistribute the load or consider having an electrician install a dedicated circuit for the garage door opener.
Internal fault in the garage door opener: There might be an internal fault or short circuit within the garage door opener itself, which is causing the GFCI outlet to trip. In this case, it's recommended to contact the manufacturer or a professional garage door technician to diagnose and repair the opener.
It's worth mentioning that intermittent issues can be more challenging to diagnose. If you're unable to identify the cause of the problem or if the tripping continues, it's best to seek assistance from a qualified electrician or a professional garage door technician who can thoroughly inspect and troubleshoot the situation.
