Thread closest to my problem: condenser fan runs constantly
Hi all: I'm hoping some of the solvers of the last issue with a similar can help me here. I have a URS48DT, and the way the condenser fan relay is wired, for the life of me I can't see how the fan is supposed to ever go off. Surely it is supposed to though, when neither compressor is runnign?
I have a wiring diagram Traulsen sent me for the UR48DT, and it correctly shows the relay coil energized by the thermostat. But my URS has such a different rats nest, I can't tell if it's supposed to be like that, or if it was wired wrong. I've tried trial-and-error swapping of the relay coil, NO and NC connectors, but the fan keeps running, independent of the thermostats being on or off.
a) There wouldn't be a relay if the fan on the URS was supposed to keep running, right?
b) Does anyone have a URS48DT wiring diagram?
