Does anyone know what this is and what it does? Th.
instruction manual states only that it is a PLA 2 Circuit connector.
My twined furnace has two of them and one was bad, they are on the 24v side of the furnace.
I removed this one and connected the two wires, furnaces run fine now. BUT want to know what they are for and is it safe to run without it.
Supplier states they are not sold separately and only part of the twining kit, (300.00 bucks)
He said it was just a connector and was fine, but want a second opinion.
