Troubleshooting Guide
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Verify cable shielding and termination, then compare firmware versions across all compressors.
When to call us
If comms drop under load, call for a controls and firmware review — nuisance trips usually start here.
Likely causes
What to check
Read the compressor fault log for the exact levitation code and check supply quality records.
When to call us
Stop restarting and call — levitation faults must be diagnosed before the shaft touches down under load.
Likely causes
What to check
Log supply voltage at the moment of the fault and check the compressor's capacitor health readings.
When to call us
Capacitor replacement is a planned job — book it rather than waiting for a hard failure.
Likely causes
What to check
Trend valve position and superheat together for at least 30 minutes at steady load.
When to call us
Persistent hunting wastes efficiency and risks liquid return — we retune the control loop on site.
FAQ
Yes, just less of it. There is no oil to change, but you still need condenser and evaporator cleanliness, refrigerant charge verification, electrical and capacitor checks, controls tuning and firmware currency.
Yes — firmware, VFD, capacitor and bearing driver work on Turbocor-based Smardt, Multistack and OEM-branded machines.
Usually degraded DC bus capacitors or an unstable supply. We measure capacitor health and log supply quality, then advise on replacement or power conditioning.
In many cases yes. We assess shell, tube and controls compatibility and model the kW/TR saving before you commit to the spend.
Correct charge, clean heat exchangers and properly tuned EXV and staging routinely recover a double-digit percentage of lost part-load efficiency on neglected plant.
Yes. We work module by module with agreed methods of statement so redundant capacity always stays online.
