LG Air Conditioner Thermistor Assembly - COV33313805

Maintain the intelligent climate regulation of your system with the LG COV33313805 Air Conditioner Thermistor Assembly. This specialized "outsourcing" assembly often features a dual-sensor configuration designed to monitor multiple thermal points simultaneously—typically both the ambient air temperature and the evaporator coil temperature. By providing these dual data streams to the main control board, the assembly allows the unit to optimize compressor frequency, manage defrost cycles, and ensure the room reaches your desired temperature with maximum energy efficiency.

The COV33313805 is built for high-performance durability, featuring sensors encapsulated in moisture-proof housing to prevent accuracy loss caused by the humid environment of the air handler. If your unit is displaying error codes like CH01, CH02, or CH06, or if the compressor refuses to engage despite a high room temperature, this assembly is the factory-spec solution.

1. Safety First: Turn off the air conditioner and disconnect it from the power source at the circuit breaker or wall outlet.
2. Access the Sensors: Open the front intake panel and remove the air filters. Locate the two sensor bulbs: one is usually clipped to the copper evaporator coils, and the other is suspended in the air intake path.
3. Trace the Harness: Follow the bundled wires from the sensors back to the electrical control box.
4. Disconnect the Assembly: Open the control box cover and unplug the COV33313805 wiring harness from the main PCB. Take note of how the wires are routed through the chassis.
5. Install the New Assembly: Plug the new harness into the PCB. Route the wires through the original cable guides and snap each sensor bulb into its specific mounting clip (ensure the coil sensor is in direct contact with the copper pipe).
6. Reassemble and Test: Close the control box, reinstall filters, and shut the front panel. Restore power and verify the unit accurately cycles the compressor based on the new thermal readings.
