I have 6 months to figure this.
While fixing ac, costomer wants me to fix problem before winter.
Carrier 80% power draft. HO complains furnace limit trips off during windy conditions. Claims this happened after reroof and replaced Bvent pipe.
8 feet of bvent with one 90 and cap.
Two service companies said termination cap needs to be extended higher. It is 12" off roof.
I cannot believe this is the solution with a power induced burner.
Anybody seen this as a reason to trip off limit.
