I have a forced hot air heating system. Even when the thermostat is
set to Off, power to the heating element in the heater stays on,
although the blower stays off. I can hear the heater clicking on and
off - I assume there is some sort of emergency shut off so it doesn't
get too hot if the blower is not on to remove the heat. The only way
to shut the system is at the circuit breaker. Does anyone know
whether the problem would be with the heater or the thermostat? I am
thinking it is a faulty thermostat since it wouldn't make sense that
the heater is receiving power with the thermostat in the Off position
unless the thermostat were faulty.
