What Does Error E416 Mean?

The Samsung Air Conditioner error E416 indicates a communication failure between the indoor and outdoor units, typically caused by the compressor shutting down due to discharge temperature protection. This safety feature prevents damage by activating when an over-temperature condition is detected, leading to a malfunctioning system that may stop cooling or display errors. If the E416 error persists, further diagnostics may be needed to inspect the compressor and related components.

Common Symptoms:

  • AC displays E416 on the control panel and stops cooling or operating normally. [微信知识](
  • Outdoor unit compressor does not run despite power present (reported by community repair sources).

Possible Causes

  • Exhaust/Discharge temperature protection activated (medium)
  • Overload protector tripped or compressor temperature sensor issue (medium)

How to Fix Error E416

DIY Fix Initial power reset and basic inspection

  1. Turn off the air conditioner using the remote or control panel.
  2. Disconnect power at the breaker or unplug the unit for at least 5–10 minutes.
  3. Reconnect power and restart to see if E416 clears (sometimes resets transient errors).
  4. Ensure outdoor unit area is clear of obstructions and well ventilated.

Technician Only Inspect discharge temperature protection circuit and compressor sensors

  1. Check the compressor discharge temperature sensor and wiring for continuity, shorts, or signs of damage.
  2. Verify the overload protector or safety switch has not tripped or failed.
  3. Measure discharge line temperature and compare to manufacturer specifications where available.
  4. Check refrigerant charge levels and ensure proper evacuation and charge (insufficient/excessive refrigerant can contribute to high discharge temps).
  5. Inspect outdoor unit ventilation and heat exchanger cleanliness.
  6. Perform any necessary repairs or replace faulty sensors, overload protectors, or related components.

Parts needed: Compressor discharge temperature sensor, Overload protection device, Refrigerant charge (if needed), Outdoor unit ventilation components

🛑 When to Call a Pro:
  • If E416 persists after basic power reset and outdoor unit ventilation checks.
  • If there is visible damage to wiring, sensors, or safety devices.
  • If compressor overheats repeatedly or shows signs of electrical/mechanical failure.
