Installing a surge protector guards against power surges and lightning strikes.
Protect your garage door opener from power surges, plus, choosing a deck finish.
Every garage door opener is vulnerable to power surges and lightning strikes. In fact, the wiring for the photoelectric eyes and the wall buttons can act like a lightning rod, pulling energy into the opener, damaging the circuit board and leaving your garage door opener dead.
A new circuit board costs $60 or more. Adding a surge protector is a
DIY project that takes about 15 minutes and greatly reduces your risk of surge damage. The units cost about $20 each at home centers, and you’ll need one for each opener. We installed a Chamberlain Garage Door Universal Surge Protector.
Unplug the opener from the outlet. Then remove the wall button wires from the opener, noting their polarity. Connect those wires to the correct terminals on the surge protector ( Photo 1).
Next, remove the photoelectric eye wires from the opener and connect those to the surge protector, following the same procedure. Finish by stripping and connecting new wires (included with the surge protector) to the surge protector and corresponding terminals on the opener ( Photo 2). Plug in the protector and the opener.
