I have a goodman it won't turn on when the thermostat calls but if I go down and open the front and push the button it will run until it gets to 70 degrees shuts off but won't turn back on when the house gets cool.help.

Check status light behind clear viewer on front panel. Blinking indicates trouble. Find service legend/label inside blower panel.

Not sure what and than what is to be done thanks

What button are you pushing? I role out or limit switch??

Does the button look like any of these?
