Guides
- Checking an air conditioner temperature sensor (thermistor)
How to check the room, coil or discharge sensor when the unit reports a sensor error: measure its resistance and compare with the exact model's table. - Pressure, low refrigerant and high discharge temperature errors: where to start
Pressure and discharge-temperature protection codes: tell a low charge from a blockage or poor heat rejection before charging.
