What it means

C488 is AC input I_limit trip error. The unit is stopping or limiting operation because that reading or component cannot be trusted. Manual trigger: C488 means AC input I_limit trip error.

Urgency

advisory

This is not usually an immediate safety hazard, but do not keep resetting it. Try only the safe homeowner check below; if the same code returns, schedule service.

Likely causes

  1. Brief power event, brownout, or unstable supply voltage
  2. Loose power connection, reactor, or outdoor electrical component problem
  3. Inverter/IPM protection or current-detection fault
  4. Compressor winding, drive, or outdoor board fault after power checks pass

Homeowner fix

Turn the system off and note any storms, brownouts, dimming lights, generator use, or breaker trips. Do not open the outdoor unit or test voltage. If C488 returns after one safe reset, leave the system off.

When to call a pro

Call a licensed HVAC technician or electrician if C488 returns, a breaker trips, or other circuits show power trouble. Tell them the Samsung meaning is: AC input I_limit trip error.
