I have a Hunter thermostat model# 42999B and my heater is not turning off no matter if I flip the thermostat to off. I have to flip the breaker in order for my unit to shut off.
Is this a thermostat issue?
We had to replace the batteries and now our heater will not turn on
It could be, or it could be a wiring issue. Make sure that your wires are in the correct place (R or Rh and W), and that they are not touching each other. If you have the unit running, and you disconnect either of the wires, it should shut off. If it does not, then the problem is in the wiring. Hope this helps
