Samsung AC E416 Error — Discharge Temperature Over Limit & Fix

Quick answer
E416 means the compressor discharge temperature has exceeded the safe limit. The unit stops to protect the compressor.
What E416 means
The compressor discharge gas has become too hot. This is a protective shutdown — the discharge sensor (working correctly in this case) has read a temperature above the safe threshold, and the board stops the compressor.
Do not keep restarting. Repeated overheating can cause permanent compressor damage.
How to fix it
What does the E416 code mean?
E416 is a discharge temperature over-limit error. The compressor outlet gas temperature exceeded the safe threshold and the protection control stopped the unit.
Common causes
- Low refrigerant charge (leak)
- Dirty condenser coil or blocked outdoor airflow
- Outdoor fan motor failure
- Restriction in the refrigerant circuit (blocked filter drier, kinked pipe)
- Compressor valve wear

How to fix the E416 error
Power off and wait
Let the compressor cool for at least 30 minutes.
Clean the outdoor coil
Remove dirt and debris blocking airflow.
Check the outdoor fan
Confirm it is running and moving air.
Restart and observe
If E416 returns quickly, the refrigerant charge is likely low — call a technician.
Technician checks
A licensed tech will check pressures, look for leaks, and assess compressor health.
Safety first: The discharge pipe can be extremely hot. Wait for cooling before any inspection. Refrigerant work must be done by a licensed technician.
Part you may need: Refrigerant service / condenser cleaning
E416 after a recent installation or service call often means the system was undercharged.
Frequently asked questions
Is E416 the same as E4?
Similar concept (discharge overheating), but E416 is the extended code with more specific meaning on newer inverter models.
How do I know if it is a leak?
If E416 keeps returning after cleaning the coil and fan check, low refrigerant from a leak is the most common cause.
