LiftMaster Capacitors

Every electronic device, including garage door opener, has a capacitor. This part stores energy that is used to start and operate the motor. When a capacitor goes bad, the opener may not turn on at all or have inconsistent power. Fortunately, this part is relatively easy and inexpensive to replace.
