ClimateMaster Vertical Stack HP nightmare!
This is my first post, any help is greatly appreciated.
The company I work for installed 60 TRM09 vertical stack ClimateMaster heat pumps in a four story bldg. Start-up was September of '12. These units are on a closed loop system. Since start-up we had bearings on 32 blower motors lock up and with this high percentage of failures the factory finally sent us enough motors to change out all 60... We've also had 2 of the replacement motors fail since December. I've changed 5 TXVs and several MPC control boards.
There are also 4 TRM12 on the same job with 1 blower motor failure so far. I've also just changed a txv on a horizontal unit.
Has anyone else had these issues with Cimate Master?
