[R-390] High Electrical hash noise level

[Les Locklear]

If people that own these Trane units with the rf hash problem raise enough cain, like Harold did, they would get it done gratis.

My new (less than 3 years old) Rheem SEER 16 heating and cooling unit has the same type of motors, but is RFI free. Just a better design I would think. Trane makes good stuff, but in the industry, they are known for noise generating air handlers. Simple grounding and shielding techniques go a long ways.

  A bit over 20 years ago, we retired and built out final home. We installed 
  two Trane Heat Pumps. A couple of months later when the Ham Shack got 
  populated, here came the "Hash". It was sectionalized to the blower motors 
  in the air handlers. I don't remember if it was isolated to heat or air 
  mode. A call to the trane engineers in Dallas resulted in Trane installing 
  two new RF free blowers. I recently replaced one of the original systems and 
  it is RF free.
