Nest Thermostat Says No Power To Red Wire Heater Will Not Work
No power to nest thermostat. There is a breaker box attached to it on the wall outside. Grip the metal ring of your thermostat and pull it gently towards you away from the wall. Some heat pump installations may have the auxiliary heat connection labelled as x w1 or w2 on the thermostat. When x w1 or w2 is an aux wire. Turn off the power to your heating and cooling system at your breaker. Another reason why theres no power to the thermostat could be due to a bad transformer or even a faulty wire running from the thermostat to the transformer.
Your thermostat should pop. Remove the wire in the w1 terminal straighten it and put it back in as far as it will go. The thermostat says there is no power to the rc wire. Nails pests like mice and rats and corrosion can all be a contributing factor. I had to turn read more. You may need to.
I just installed a nest thermostat. If there is a common wire installed the nest thermostat will not power share. Turn off power to your system at the breaker box or system switch. You should verify that the x wire on the old thermostat is not a common wire.
