Furnace issues- 2018 Jayco North Point
Yes, I have a 2017 NorthPoint 377 and furnace has not worked for 2 years. I have had the thermostat, circuit board on the furnace, and breaker switch on the furnace replaced. Still keeps tripping that circuit switch, tech pulled my furnace 3 weeks ago and ran it on the bench everyday with no issues. So as you stated either airflow or the ducts are two small.
