Samsung Heat Pump Error Code E206

E206 means the compressor has been shut down because the discharge temperature sensor detected a temperature exceeding 135°C at the compressor outlet. This is a protective fault designed to prevent mechanical damage to the compressor. The cause could be a refrigerant system issue such as low charge or a closed service valve, or it could be a failed temperature sensor reporting an incorrect value. A technician with manifold gauges and an S-net diagnostic tool is needed to confirm the root cause.

No. The E206 error triggers a compressor shutdown specifically to protect the unit from damage caused by overheating. Attempting to bypass or repeatedly reset the system without resolving the underlying cause risks serious damage to the compressor, which is one of the most expensive components in the system. The heat pump should remain off until the fault is properly diagnosed and repaired.

Repair costs vary depending on the root cause. If the fault is a closed service valve or a minor refrigerant adjustment, costs may be relatively low, typically in the range of $100 to $300 for a service call and labor. A failed discharge temperature sensor replacement could run $150 to $400 including parts and labor. If the compressor itself is damaged due to sustained overheating, replacement costs can range from $1,000 to $2,500 or more depending on the unit capacity and installation complexity.

Diagnosing and repairing E206 requires specialized tools including manifold gauges and the Samsung S-net diagnostic system, along with EPA certification if refrigerant handling is involved. Homeowners can check that the service valves on the outdoor unit are fully open, but beyond that, this repair should be handled by a qualified HVAC technician. Attempting to add refrigerant or replace components without proper diagnosis may not resolve the fault and could cause additional damage.

A power reset may temporarily clear the fault and allow the unit to restart, but the error will return if the underlying cause is not corrected. If the discharge temperature exceeds 135°C again during operation, the control board will shut the compressor down and display E206 again. Resetting without diagnosis is not a repair and may delay proper service while risking compressor damage.
