I have a Craftsman opener, don’t know what the model is but it’s 21 years old. Never had any problems until now. We have two remotes plus the one that is built into the car. The door opens and closes fine with the button on the wall. The door will open with all three remotes but will not close with all three. Absolutely nothing happens, no noises, flashes lights, etc. Does anyone have any ideas or is it time to just get a new one?
