Samsung Air Conditioner Error Code E496

E496 indicates a DC voltage sensor error associated with Fan1 on your Samsung air conditioner. The control board has detected that the DC-Link voltage reading from the Fan1 circuit is abnormal or absent. This error is designed to protect the fan motor and inverter components from damage caused by incorrect operating voltages.

No, you should not continue running the unit when E496 is active. The error indicates a fault in the voltage sensing circuit for the fan motor, and continued operation without proper fan control could cause overheating of the compressor or inverter components. Power off the unit until the fault is diagnosed and corrected.

Repair costs vary depending on the root cause. If the fix involves reseating or replacing a wiring harness connector, costs are relatively low, typically in the range of $75 to $150 for a service call. If the inverter board or fan motor requires replacement, costs can range from $200 to $600 or more depending on the specific unit model and parts availability.

Start by inspecting the DC-Link voltage connection wire for Fan1, checking for loose connectors, corrosion, or visible damage. If the wiring appears intact, further diagnosis requires measuring actual DC-Link voltage at the relevant terminals to determine if the sensor, inverter board, or fan motor is at fault. Repairs beyond basic wiring checks typically require a qualified technician due to the high DC voltages present in the inverter circuit.

A power reset may temporarily clear the error display, but if an underlying fault exists in the DC-Link voltage sensor wiring, the sensor itself, or the inverter board, the code will return once the unit attempts to operate Fan1 again. A reset is useful for confirming whether the fault is intermittent, but it does not resolve the root cause.
