We have two garage doors, the larger a two car width and the smaller a single car width. We use a clicker that can control both separate motors. The smaller always works perfect, but the larger will work fine at times, but other times you have to click the button several times to get it to respond. Same thing on the wall mounted buttons, it will be very unresponsive at times (larger side only). We usually can always get it to open or close eventually. Where should I go from here to try and fix this? I want to DIY it.
