Heat kick in every hour for 15 minutes in Bryant Plus 90 Gas furnace.
Hi All:
I have Bryant plus 90 gas furnace and used to have Lenox Mercury thermostat. Heat will kick in for 15~20min after every one hour. Does not follow thermostat. So just change a new Honeywell programmable thermostat, but it is still doing the same.
At the furnace LED indicator blinking 3 quick blink and one solid long one. Per the cause mentioned it in the panel it is for high wind, or improper size of the air intake, Inducer motor problem, etc. But if this is due to these causes why furnace is still kicking in every hour for 15~2o minutes?
Friends, please let us know how should we solve this.
Thanks so much.
