I have a GB142 and the temperature rises past the thermostat

Customer Question

I have a GB142 and the temperature rises past the thermostat setting once in while. Seems like something sticking or stuck. It's not the everyday temperature rise that you get from daylight sun. Last night it was up to 77 from setting of 69. I have changed Thermostat and New Circuit board. Furnace is 4 1/2 years old in upstate N.Y. Thanks, Brad

It seems my colleague has stepped away. My name is ***** ***** I'll do what I can to help. This sounds like it may be a zone control problem. Do you have more than 1 zone/thermostat? if so do you have zone valves or circulators/pumps for zone control?
