Samsung Heat Pump Error Code E114

E114 indicates that the system detected a momentary power interruption and temporarily stopped the compressor as a protective action. It is not a component failure or a true fault code. The system uses this shutdown to prevent compressor damage from unstable voltage during or after the power event. Normal operation typically resumes automatically once stable power is confirmed.

A single isolated E114 event is generally not a safety concern. It is the system protecting itself from a brief power disruption. However, if the code appears repeatedly, the underlying cause could include overloaded circuits, deteriorating wiring, or a failing breaker, any of which should be addressed promptly to prevent more serious electrical hazards.

If the cause is a utility fluctuation or a loose connection, the cost can be minimal, covering only a service call fee, typically in the range of $75 to $150. If the issue involves replacing a disconnect switch or contactor, parts and labor costs generally range from $150 to $400. Wiring upgrades or electrical panel work can increase the cost further depending on the scope of the problem.

In many cases, the system will recover and restart on its own without any action needed. If the code persists or returns frequently, inspect the circuit breaker, disconnect box, and all wiring connections to the unit for looseness, corrosion, or signs of arcing. Recurring E114 events point to a power quality or wiring issue that should be evaluated by a qualified technician or electrician.

The system is designed to clear this status and resume operation automatically once power is stable. A manual reset by cycling the breaker may help if the unit does not restart on its own. However, resetting will not address any underlying power supply problem, so if the code returns, further electrical diagnosis is needed.
