How to troubleshoot a Blue Box Chiller with no compressor running and fans stopped?
- E
  Elizabeth MarshallAug 16, 2025
  If your Blue Box Chiller's compressor isn't running, the fans have stopped, and the display is off, here's what you can check: 1. **Mains Power:** Verify that the chiller is receiving mains power. 2. **Main Power Switch:** Ensure the main power switch is in the "I" position, not "O". 3. **Control Circuit Power:** Check fuses FU50, FU51, and FU52, and inspect the transformer's operation. 4. **Phase Sequence:** If relay KA5 has only a green LED lit, invert two of the phase wires of the power supply line. Both green and yellow LEDs should light upon restart. 5. **Relay KA5 LEDs:** If relay KA5 has both green and yellow LEDs off, check fuse FU56. If the fuse is okay, replace the phase sequence relay.

Why is my Blue Box KAPPA V SR showing a 'Low Pressure' alarm and the compressor is not running?
- B
  Brianna DixonAug 19, 2025
  If your Blue Box Chiller displays a 'Low Pressure' alarm and the compressor is not running, consider the following: 1. **Glycol Percentage:** Ensure the hydraulic circuit has the correct percentage of glycol. 2. **Refrigerant Charge:** Check for leaks and recharge both circuits if they have insufficient refrigerant. 3. **Fans Contactor:** Verify the voltage across the contactor coil and its continuity. 4. **Fan Motor:** Inspect the fan motor and replace if faulty. 5. **Water Flow:** Check for sufficient water flow to the evaporator in the hydraulic circuit. 6. **Defrost Set-Point:** Ensure the defrost set-point is correctly set.
