Question:
I have a 1/2hp Sears garage door opener that had the capacitor burn
out during a power surge.
I can find another cylindar shaped capacitor in the manual but this
isn't the one I need.
The one I need is a two wire type with a round bulb at the end which
is attached to the terminal block screws where the power comes in.
I have called Sears and they have been no help in this at all.
Since there are a lot of capicators out there I was hoping someone
would know the right one for a garage door opener.
Answer:
-If you can find a overhead garage door company in your area, you can take
your old capacitor in and they can match you up with the right one.
-Does the parts book that came with the garage door opener call it a
capacitor? if not then its not a capacitor... might be just part of
the logic board and if so then you got to buy the whole board as they
dont sell just parts any longer..... and the one big cap. thats in my
garage door opener for the motor is about $45.00 from sears.. and being
as my opener is about 20 yrs. old i would look for a real capacitor some
place else like an electric motor shop... they can test it to make sure
its bad or if its a capacitor at all.....
-1) If it is a Sears product, then a Sears repair center has
the exploded diagram of every part that can be replaced in
every Sears product. Anyone saying otherwise at Sears is
either ignorant of how Sears works or has an agenda.
2) There are probably at least 10,000 different capacitors.
You have provided no numbers nor even the function of this
capacitor. Therefore anyone who provides a replacement part
is probably trying to take revenge. If you don't get the part
from Sears or the manufacturer, then you better have the long
list of specifications including surge voltage, temperature,
type of material used to make the capacitor, ESR, polarity,
and other critical numbers. Better return to Sears and find a
more honest person, or buy a new garage door opener from a
company provides support.
3) Was it a surge or have you speculated? Many reasons for
failure. Surges occur typically once every eight years. They
are that rare and are directly traceable to human failure. If
it was a surge, then you also want to fix the reason for your
failure. But again, don't speculate. Surge protectors are
not surge protection. But that is another topic.
