[color=#000000]Hello,[/color] I have a Carrier 58MVC and the inducer fan broke off completely from its center mount. I replaced it last month and yesterday it broke again. This (horizontal) system had been working flawlessly since 2009. When I removed the housing, there was some water still in there. No clogs found from the drain hole or the connector hose. what could cause the fan to keep breaking like this? Clogged exhaust that created back pressure to the fan? thx

I have a lennox g51mp that is around 7ish years old. Last moth had issue where it wouldn't fire and seemed like condensation drain issue. Cleaned that up and seemed to fix it. Came home from out of town and found my inducer fan running but no heat and house down to 56. Shut thermostat off and back to on no change. With thermostat off I cycled power to furnace. Once I turned back on the inducer immediately started. When I kill power for 10-15 minutes then the inducer doesn't start immediately. Pressure switches all tested good with multimeter. It ran all night friday without issue but Saturday am it was doing it again and how was down to 59. It took about 10-15 min with power off to furnace for it to work correctly again. When it is stuck with inducer running constantly the lights are showing normal operation. I am thinking control board issues or thermostat issues. Any ideas?
