Performed furnace diagnostic Elk Grove on 17 yr old split Goodman system furnace in attic. Turned system on could hear system inducer turning on, then burners igniting, then blower turning off, then system would turn off, light and then go off. Found dirty flame sensor, cleaned flame sensor and made sure wires are tight. Unit is making extra noise, blower seems to be out of balance. Could also be an issue with the control board. Control board looks ok for now. Will keep an eye on the blower and the control board. Ran system for 10 min no issues, cycled system between the zones no issues turned system off and on at thermostat no issues.
