1. SWAP the 2 Motor wires. This will cause the system to work in reverse.
2. If now, the room goes OUT but not in, then the control board with the relay's is bad. Report back. Doug
At first it would go out but not in, yesterday it wouldn’t go either way.
My thought was corrosion on the wires from the water leak that was in the area where the board was located but the board looks dry with no corrosion.
It may be the ground, I sure wish I had my multimeter with me! Last night I told me wife that I guess I could run a hot and ground to the battery - but I don’t have extra wire with me either lol.
