My furnace does not shut down and continues to heat after reaching its set point. This happens after it has cycled approx. 8/10 times. In other words it is hot. I have shut it down at the thermostat but a couple time that approach did not work. Hmmmm Installed a new thermostat, it is a 5 button, but not go. I am about to pull the furnace but with scant knowledge of how it operates hate to have to shot gun the repair. Bad board or relay or something else? Anyone with knowledge or wanting to make a educated guess will be greatly appreciated. Thanks
