I have a older Goodman furnace that fires up and raise my temp by a degree or two an then cuts out and goes to re-ignite but will not until you turn the power off and then back on and the cycle repeats itself.
I have taken out the flame seņor and cleaned it and installed a new thermostat but neither fixed the problem.
PLEASE HELP ME!
