EBG61107014 Genuine Return Air and Pipe Thermistor Assembly for LG Air Conditioners, Dual Temperature Sensor

This genuine LG thermistor assembly, EBG61107014, combines two temperature sensors in one assembly: a return air sensor and a pipe sensor. It belongs in the indoor unit of LG air conditioners, where the control board reads both to manage the room temperature and protect the coil. With no model list on file, match EBG61107014 to the number on your old sensor plug or send us the indoor unit's model number.

How return air and pipe sensors control an LG air conditioner

The return air sensor measures the room air entering the indoor unit, which tells the board when the set temperature has been reached. The pipe sensor reads the coil temperature, so the board can stop the coil icing up in cooling and manage warm start and defrost in heating. A faulty thermistor gives the board false readings. The unit may stop short of the set temperature, run without stopping, cycle on and off, blow cold air when heating starts, or show a sensor error code. Damaged leads and corroded plugs cause the same symptoms.

Part details

• Genuine LG part EBG61107014
• Two sensors in one assembly, return air and pipe
• For the indoor unit of LG air conditioners
• Match the number on your old sensor plug

Fitting the thermistor assembly

Turn the air conditioner off and isolate it at the circuit breaker. Note exactly where each sensor sits before removing it, as the pipe sensor normally clips into a pocket on the coil and the return air sensor sits in the airflow near the filter. Push the pipe sensor fully home in its holder so it reads properly. A licensed technician should carry out this work.

Questions about this part

How can I check the old sensors?

Unplug the assembly from the board and measure each sensor with a multimeter. The resistance should change smoothly as you warm the sensor in your hand. A reading of zero, an open circuit, or one that doesn't move with temperature points to a failed sensor.
