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.

How do I check the proper draft, and look for a diagnostic light? Thank you for your help!

I guess I have to re instate my question, I replaced the flame sensor, switch and now, how can I look for the proper draft and the diagnostic light flash code?

Here's a link to a Goodman unit. The draft inducer motor is called vent blower.

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.
