    Heater won't come on
    My central heat system won't start. I turn on thermostat no response from heater. It has auto start no pilot. The problem is not the thermostat.

    How do you know that it is not the thermostat?

    Turn the thermostat off and go to the furnace, take the doors off, now use a piece of tape to tape the door swith so it will have power.

    Now use a temporary jumper wire to connectfrom the W terminal on the low voltage part of the circuit board to the R terminal in the same place. This should make the vent assist blower motor come on. After about
    15 - 20 seconds the hot surfice ignitor should start to glow, another 15 seconds the burners should come on and then 30 to 45 seconds the main blower should come on.

    Now if you will follow this procedure and then let me know what happened maybe I can help you work it out.

    Please respond if this helped or not.

    Can you tell us exactly what happens at furnace? Does it do anything. Does it have power? Can you tell us what make and model the furnace is. Do you know how to test for power? Is it gas, electric, oil,, 80 or 90 percent efficient. Does ac work? Need some details and we would love to help.
