RE: Traulsen woes…

G31010JC… weighed the charge in after pulling it to verify it wasn’t low, weighed it in exactly. Ran the system and checked on it once it reached temp. Running a very low subcool, and a normal to high SH. This has a txv, which had just been replaced by another tech, along with the evap and drier. Tech support didn’t seem worried about the low head pressure (200 in a room that was 75 degrees r404) should have been more like 255 or so based on the ambient temp. It finally pulled down to -5 deg F, and shut off,  but we got a call that it wasn’t pulling below 8 degrees. The case was completely empty and hadn’t been messed with since the initial repair.

Daniel a few questions?

  1. Does your compressor have weak valves?  ( Try disconnecting the CFM and see if the head drives up to 400+, and to test the suction valve grab the suction line after you unplug the unit and see if it gets hot)
  2. Does this unit have the Intellitraul digital display?  If so what is your coil temp and box temp (Coil temp is EL in service settings)
  3. Was the txv that was installed the Oem txv or an off the shelf TXV?
