H0010401830A Genuine Temperature Sensor for Haier Air Conditioners, Split System Thermistor Sensor

Haier part H0010401830A is a genuine temperature sensor for Haier air conditioners. Split systems use several sensors, typically for room air, the indoor coil and the outdoor unit, and each has its own job and connector. The description doesn't say which position this one fills, so look for a number on the old sensor's lead or in your unit's parts list before ordering.

Haier air con error codes and temperature problems

An air conditioner's control board relies on its temperature sensors to decide when to run the compressor, how fast to run the fans and when to defrost. Most are thermistors, whose resistance changes with temperature. When one drifts or fails, the system may show an error code, stop early, run without reaching the set temperature, cycle on and off, or ice up. A sensor that has come out of its clip on the coil can cause the same symptoms, so check its position before replacing it.

Replacing an air conditioner sensor

Turn the air conditioner off at the isolator and the circuit breaker before opening any covers. Split systems are hard-wired, so this job should be done by a licensed electrician or air conditioning technician. Trace the old sensor's lead to the control board, note its connector and how the probe is clipped or inserted, then fit the new sensor in exactly the same spot.

Questions about this part
