Have a new Trane XV90 two stage condensing gas furnace. As soon as the Inducer motor starts up a TV in the floor above it has it's picture completely filled with RF noise--static, snow, all kinds of white lines through out. Initially, the picture was almost unwatchable.Important to note that the TV is using Rabbit Ears. To date, my HVAC Co per Trane's recommendations has done the following: Checked the 110 volt supply to insure that a good ground is in place. Replaced the wiring harness to the inducer motor with a "shielded" harness. In actuality, about 6 inches on either side of the harness is not covered by the shielding. Replaced the control board. Significant improvement with the harness replacement but the RF noise is still there and still distorting the TV picture. There is absolutely no question that the problems appears as soon as the inducer motor starts running but surprisingly, Trane hasn't picked on it yet. HVAC Co now waiting on Trane for more direction. Looking for any comments or suggestions that I can pass along to my HVAC Service manager. He has been doing all he can in order to rectify the problem but at the same time must follow Trane's instructions in order to get paid for his time. MLD
