    no heat

    I have checked all control wiring up to the out door unit and i have 24 volts and know that it is calling for heat. The contactor is not pulling in, and also the auto is not working on the heat side but works for the a/c. Can anyone help and suggest why I am not getting any heat?

    Check for voltage with a lamp or put a resistor across your leads sometimes our meters are too senstive and the slightest feedback will show voltage but under load it is not there.
