While error codes can differ from model to model, there are some codes you’ll be more likely to encounter. To determine what your error code can mean, consider the following:
- Is your system a mini split air conditioner or a mini split heat pump?
- Are there clear signs of what is happening? A loud noise coming from a key component, for example.
Here are a few of the more common error codes for Lennox mini splits.
E1 – Indoor / Outdoor Unit Communication
在一般情况下, an E1 error code signifies that communication between the mini split system’s indoor and outdoor units has been hampered. It could be facing intermittent connection issues or have failed entirely. When the indoor and outdoor units can’t communicate with one another, it will be unable to adequately balance indoor temperatures.
E5 – Voltage Protection or Temperature Sensor Error
If you own a mini split heat pump, an E5 error may refer to a problem with the system’s voltage. A repair technician from 网赌博彩十大信誉平台 may refer to it as overcurrent protection. Both excessively high or low voltage can create this error code.
For mini split air conditioners, this code can also indicate voltage issues. In other cases, it’s pointing you to a circuit problem with the outdoor temperature sensor.
An E6 error code can also refer to a communication problem between the two units, 类似于E1代码. It could also be an issue with one of the temperature sensors.
P4 – Compressor Drive Error / High Temperature
A P4 error code will usually be concerned with your mini splits compressor system, 位于室外机内. When the compressor drive is faulty, the most likely cause is excessively high temperatures. A high temperature at the discharge line can also trigger a P4 code.
P6 – Compressor Switch Open or Drive Board Failure
Your mini split system will have computer boards that make sure the indoor and outdoor units can communicate with one another. If the drive board is damaged, a P6 error code is common.
当温度超过安全水平, a safety switch will protect the electrical components of your mini split system, including any components that control the outdoor compressor. If this switch is open, the P6 code can appear. You may also find the P6 code if the compressor is facing high or low pressure concerns.
Don’t forget that in general, error codes are specific to each model of a Lennox mini split system. Your manual will offer a guide for these error codes and what they can mean. But since many of these codes stem from electrical problems, professional experience is typically required.
