My house has a split system, The problem I am having is that the compressor will run and the fan will run, however when I go to the thermastat and turn off the unit completely it doesnt stop, it keeps going. I went in the attic to the other half of the system and took the panel off, there is this button which I think its connect to a relay. When I took off the panel the unit stopped running, when I put it back on it started running.
My question is how the hell do I get my unit to start working with the panel on and be able to go to my thermostat and turn it off / on.
Think I have a bad relay?
