So The door would periodically stop mid use on either direction and need to be
restarted sometimes a few times to get the door to close or open fully. There
are times that it works just fine for a few cycles, then here we go again.
Wiring is ok. Transmitters all check out. Neither an issue as I have multiple.
Checked and adjusted the force settings to either end (7) positions. No luck
there either. Finally I figured it must be the capacitor. It is a 40 MFD 220VAC
Towa Motor Starting Capacitor ....................of course it cannot be found
anywhere. Overhead Door sent me a "replacement" capacitor 36-43 MFD but now the
problem is worse. Door will not move at all. Motor starts and hangs immediately.
Anyone out there got any suggestions ?
Door openers will stop if they jam or hit something. If the door is not
easily moving in the track it will stop. Disconnect it from the opener
and be sure it goes up and down smoothly, bearings are lubricated, no
Most large capacitors are not made to very close specifications. So the
36-43 MFD should be fine. You did not mention what kind of opener you
have as far as the operation type. Chain, screw or some other drive ?
Have you lubercated all the moving parts of the door ? I have a screw
drive and every year or two I lubercate it.
Disconnect door from drive and exercise motor. Unlikely there is where
the problem is (or was); this'll show it runs fine in all likelihood
(and probably would with the old cap back in place of the new one as
well would be my best guess).
