H0010401826 Genuine Suction Temperature Sensor for Haier Air Conditioners, Suction Pipe Thermistor Replacement

H0010401826 is a genuine Haier suction temperature sensor for air conditioners. It's a thermistor that clips onto the suction pipe, the return line to the compressor, usually at the outdoor unit, and reports the pipe temperature to the control board. The board uses that reading to manage the refrigeration system and protect the compressor. No models are on file, so check the number on the old sensor or your unit's parts list before ordering.

Air conditioner error code or poor cooling?

Sensors like this are simple resistors that change value with temperature. When one drifts out of range, breaks inside its sheath or loses contact with the pipe, the control board gets a false reading. Symptoms include a sensor error code, the system shutting down soon after starting, weak heating or cooling, or the compressor running harder than it should. A damaged lead or corroded plug can cause the same faults. A technician can check the resistance against the chart in the service manual.

Part details

• Genuine Haier part H0010401826
• Suction pipe temperature sensor
• Thermistor type sensor for air conditioners
• Reports suction line temperature to the control board

Fitting the suction sensor

Air conditioners are hard-wired, so isolate power at the switchboard and leave the unit a few minutes before opening it. This job should be done by a licensed air conditioning technician or electrician. Trace the old sensor lead back to its plug, noting the route and cable ties. Fit the new sensor in the same pipe holder with good contact, refit any insulation over it and test the system.

Questions about this part

Will any air conditioner sensor do?

No. Haier sensors have different resistance values, lead lengths and plugs depending on their position and the model. This one is listed as the suction sensor, so match the number on your old sensor or the model's parts list before ordering.
