Frick RWB / RXF screw

Every guide in the Frick (Johnson Controls) Frick RWB / RXF screw library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.

• 1

  Oil contamination from moisture or refrigerant causing bearing surface pitting

• 2

  Bearing fatigue after extended operating hours

• 3

  Rotor imbalance from refrigerant liquid slug damage to rotor lobes

• 4

  Misalignment at the motor-to-compressor coupling

• 5

  Oil return float trap stuck closed preventing oil from draining back to the sump

• 6

  Oil return line partially blocked by a foreign particle or valve restriction

• 7

  Oil viscosity too low at the operating temperature allowing excessive carryover

• 8

  Compressor running at reduced capacity sending less gas flow through the separator
