Why is my Panasonic 140 making excessive noise?
- R
  Robin LunaAug 23, 2025
  Excessive noise from your Panasonic Chiller could stem from various sources. Check these: * Vibrating pipe work: Attach the pipe work correctly. * Whistling noise from the thermostatic pressure relief valve: Top up the refrigerant fluid charge. * Noisy compressor: Check the condition of the valves. * Seized bearings: Replace the compressor. * Also check the pipe work attachments, the dehumidification filter, and the tightness of the compressor attachment nuts.

What to do if my Panasonic 140 Chiller unit operates continuously but isn't cooling?
- B
  brandysullivanSep 12, 2025
  If your Panasonic Chiller runs constantly without cooling, it might be due to several reasons: * There might be insufficient refrigerant fluid. In this case, top up the refrigerant fluid charge. * A clogged dehumidification filter could be the cause. Try replacing the dehumidification filter. * Reduced output from one or both circuits. Check the compressor valves and change them if necessary.
