Are you saying this switch is a breaker? Mine is on.
I don't have two blue wires at the thermostat. I do have the two blue wires on the heater that make up when the over-heat thermostat is closed and sail switch closes. As I said originally, when the two blue wires from the heater are tied together and 12vdc are supplied by an external battery to the red (+12v) and yellow (-12v), hooked up the gas line and the heater started and ran. When I matched up the wires as they were, originally (see last post) matched, nothing happens.
The other 2 functions of the thermostat, ac and heat pump, work correctly.
I don't have a clue where the relay is located where the tiny wires from the thermostat transfer to the heavier wires to the furnace.
