    My goodman heater keeps shutting off

    Age:
    6 years
    Type of system:
    Heating and air conditioning

    The heating system keeps on shutting off, and I don't have heat. I have to reset it in order to heat the house, but then it does not reach the desired temperature and it shuts off. Please help!

    Clean flame sensor, check pressure switch and proper draft, look for a diagnostic light to flash a code when system is locked out.

    Here's a link to a Goodman unit. The draft inducer motor is called vent blower.
    http://www.goodmanmfg.com/Portals/0/pdf/CB-GCV9.pdf

    To check the draft verify that the motor runs and there are no blockage in the vent (not too likely but it can happen). If this motor it is starting to go bad, it may run for some time but then it will stop, this will cause the unit to shut the gas valve.

    If you want to test if the motor runs OK, disconnect it and connect it direct to make it run.
    If it runs and stops while connected it is bad.

    Suerte.
