Noisy Suburban Furnace fan
been researching all the Suburban furnace repair sites and here. None of them mention my problem on a 2004, NT16SE. The fan motor is very noisy and even rattles loudly once in a while (wakes us up at nite), and the whole furnace even vibrates a little.
Took the insides out of the metal box and found that the motor shaft moves back and forth a little and makes a metallic noise that probably creates the rattle. The fan rotates evenly as does the combustion air wheel. I thought an electric motor shaft would have a little play in it?
It seems obvious to me that the motor is worn out but just want to be sure before ordering a new one at $80. I tend to diagnose problems before taking things apart.
