LG Air Conditioner Error Code E262

The E262 code means the discharge temperature sensor for compressor 1 has physically detached from its mounting holder on the discharge pipe. The sensor is a thermistor that monitors the temperature of refrigerant leaving the compressor. When it loses contact with the pipe, the control board cannot read accurate temperatures and shuts the system down as a precaution. Reseating the sensor in its clip is the primary fix.

You should not continue operating the unit with this error active. The discharge temperature sensor is a critical safety input that protects the compressor from overheating. Without a reliable reading from this sensor, the system cannot detect a dangerous high-temperature condition, which could lead to compressor damage. The system will typically shut down automatically when this fault is detected.

If the sensor only needs to be reseated in its holder, a service call cost of roughly 75 to 150 dollars for a technician visit may be all that is required. If the sensor holder clip is broken and needs replacement, parts are generally low-cost, keeping the total repair in the 100 to 250 dollar range. If the sensor itself is damaged and requires replacement, costs may rise slightly depending on parts availability and labor rates in your area.

In many cases, yes. The first step is to locate the discharge temperature sensor near compressor 1 on the discharge line and firmly re-insert it into the sensor holder bracket. If the holder clip is intact and undamaged, this may resolve the error immediately. However, if the holder is broken or you are not comfortable working around refrigerant lines and electrical components, a qualified technician should perform the repair.

A simple power reset will likely not permanently clear the E262 error if the underlying issue is not corrected first. If the sensor is still detached when power is restored, the fault will return as soon as the compressor attempts to operate. You need to physically reseat the sensor in its holder and confirm it is secure before resetting the unit.
