My garage door opener stopped working and I found it's because of the sensors. It's a very old unit from the late '80s. Sears brand, not even Craftsman.
My concern is, since this is a very old unit, they obviously don't sell the original sensors anymore. Searching online, the advice is to go with Chamberlain or Craftsman brands since they're compatible.
However, the wires connected to my garage door sensors are green/yellow, and the newer brands connect to black/white wires.
If I buy the Chamberlain sensors, would they even work if I try to power them with green/yellow wires? If not, what can I do besides needing to replace the whole garage opener? Thank you, any help would be appreciated.
