Our Goodman furnace ( model # A48- 20) is turning itself off and on when it comes on. It will kick on, run for a few seconds, turn off quickly, then kick back on again. It will run fine after that.
He ordered a sequencer and 4 limit switches from here & received and installed them today. A friend said it might be the thermostat but we're not sure.

Thanks for any help

Is it still doing it after new parts installed ?


Is it just the blower motor or blower and elements doing it ?



Does your t-stat have a heat anticipator setting inside (dial with pointer).



Thanks,
Robert

Thanks for the reply, but we have figured out that it was the fan relay switch. We ordered one from you (great service! ) and it is working fine now.

Thanks again,
