What it means

C416 is Discharge temperature (DIS-TH) sensor error. The unit is stopping or limiting operation because that reading or component cannot be trusted. Manual trigger: C416 means Discharge temperature (DIS-TH) sensor 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. Dirty filters, blocked coil airflow, or an outdoor clearance problem increasing pressure or temperature
  2. Low charge, overcharge, leak, or refrigerant-flow restriction
  3. Discharge, pressure, or refrigerant sensor reading outside range
  4. Compressor, valve, or outdoor board issue after airflow and charge are verified

Homeowner fix

Turn the system off with the remote, then power cycle once at the breaker or disconnect if you can do that safely. Expected result: a temporary sensor fault clears; if C416 returns, stop resetting and schedule service. Do not remove panels.

When to call a pro

Call a licensed HVAC technician if C416 returns after the safe homeowner check. Tell them the exact Samsung code and meaning: Discharge temperature (DIS-TH) sensor error.

Repair vs replace

Sensor and control faults are usually repairable. Compare repair with replacement only if the system is older, out of warranty, or several sensors or boards are being quoted together.
