I have a goodman gas furnace, gms91155dxa for about a year. Recently I notice the furnace repeats on and off while it didn't reach at set temperature. After the heater is on, it runs some minutes and it shuts off itself. And the draft inducing motor runs, the ignitor is on and gas blows and in seconds with clicking sounds gas as well as draft inducing motor shut off.
And soon it repeats over and over again. What could be wrong,,
