Samsung Air Conditioner Error Code 265

Error code 265 on a Samsung air conditioner indicates a SUMP sensor dislocation error. The control board has determined that the sensor monitoring the condensate sump area is not in its correct mounted position or is producing readings inconsistent with proper placement. The unit stops operating to prevent damage from inaccurate sensor data.

A simple power reset is unlikely to permanently clear error code 265 because the fault is caused by a physical condition, specifically the sensor being out of position. The error will typically return after reset if the sensor has not been properly repositioned or secured. The underlying mechanical issue must be corrected first.

If the fix only requires repositioning the sensor, a service call labor charge is the primary cost, typically ranging from $75 to $150 depending on your region and technician. If the sensor mounting bracket or the sensor itself needs replacement, parts costs can add an additional $20 to $100 or more to the total repair bill.

Start by locating the SUMP sensor and confirming it is properly seated in its mounting bracket or clip. If the sensor has shifted, reposition it firmly and ensure the wiring connector is fully attached. If the mounting hardware is broken or the sensor appears damaged, those components will need to be replaced before the unit will operate normally again.

It is not recommended to attempt to bypass or ignore error code 265. The SUMP sensor monitors the condensate area, and operating the unit without accurate readings from this sensor could lead to water management problems such as overflow or undetected drainage issues. Address the sensor positioning before resuming normal operation.
