My heat won't come on nor the fan and my house is all electric. I checked the circuit breaker, its fine.

Does anything happen in the furnace when you turn the thermostat up.

You say you checked the breaker, are you sure that you checked the right one, the one you should check is a double breaker and will brobably be a 50 or 60 amp breaker. If you find it flip it all the way off and then back on.

Other than that we would need to now what brand and what is the model and aprox age of your furnace.
