Replacing a garage opener bulb
Ordinary light bulbs often burn out quickly in garage door openers, but are CFLs the answer to the problem? We contacted the two largest residential
garage door opener companies to
ask about CFLs and possible damage to the opener. Both companies state
that CFLs will NOT damage your
opener. However, since electrical
interference from the CFL ballast can
reduce the operating range of your
transmitter, they recommend always
using an incandescent bulb.
Garage door openers produce a lot
of vibration, which can kill incandescent bulbs prematurely. To fix the problem, tighten all
the bolts on your unit and make sure
it’s solidly mounted to the ceiling.
Then, install a “rough service” bulb (available at hardware stores and home centers).
These bulbs have heavy-duty filaments
with extra support wires to
keep them from breaking. Before anyone
sends us letters about how “ungreen”
incandescent bulbs are, wait a
minute. The average opener light is
on only a few minutes a day.
If your opener doesn’t have a plastic
lens, the bulb is unprotected, so
choose a rough-service bulb with
protective coating. The coating prevents
the glass from shattering if it’s ever struck.
