Samsung Air Conditioner E416 Error Code

Compressor running too hot. Here is what it means and how to clear it, easiest fix first.

E416
May need a pro

The temperature of the refrigerant leaving the compressor has climbed too high, so the outdoor unit has shut down to protect itself. Poor airflow at the outdoor unit can contribute; other causes involve the refrigerant system and need a technician.

Shown as E416 or C416. E251 or C251 is a related code meaning the discharge temperature sensor itself has failed. Meanings here come from Samsung service and installation manuals for specific model families; codes vary by series and region, so check your owner's or service manual.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung E416

  1. Clear the outdoor unit

    Switch off the breaker. Remove anything stacked against the outdoor unit and gently brush leaves and lint off the coil with a soft brush, taking care not to bend the fins.

  2. Clean the indoor filters

    While the power is off, wash the indoor filters so the system isn't starved of airflow.

  3. Reset the power at the breaker

    Switch off the breaker that feeds the air conditioner (some systems have separate breakers for the indoor and outdoor units, so switch off both). Wait about five minutes, switch the power back on and restart the unit to see if the code clears.

When to call a technician

If the code returns, a technician needs to check the refrigerant charge and compressor. Don't open the refrigerant lines.
