Keeprite’s central air conditioning units epitomize cooling excellence. Designed for peak performance, these units guarantee homes remain comfortable during sweltering months. Their efficiency ratings cater to different household requirements, balancing initial costs with long-term savings. Notably, the units operate quietly, ensuring serene indoor environments. The durability of components and corrosion-resistant finishes further extend the product lifespan.
E1: Low Pressure Protect
This indicates that there might be an issue with the refrigerant or its pressure, possibly pointing to a leak or blockage.
E2: High Pressure Protect
The refrigerant pressure is too high, which can be caused by blockages, overcharging, or issues with the compressor.
E3: Compressor Overload
The compressor is working harder than it should, which might indicate issues with the capacitor, refrigerant, or other components.
E4: Overcurrent Protect
There’s too much electrical current, suggesting potential electrical problems or malfunctioning components.
E5: Open Circuit or Out of Range Thermal Sensor
The thermal sensor or thermostat is malfunctioning or there’s an issue with its connection.
E6: Communication Failure
There’s a communication issue between the indoor and outdoor units or between the main board and the control panel.
E7: Coil Temperature Protect
The coil temperature is too high or too low, which can be caused by airflow issues or refrigerant problems.
E8: Overheat Protect
Components of the air conditioner are overheating, which can be a result of blocked vents, malfunctioning fans, or other issues.
E9: Fan Motor Problem
The fan motor is malfunctioning, not running at the desired speed, or not running at all. This can be due to electrical issues, blockages, or motor wear and tear.
EA: Water Drainage Problem
There’s an issue with the drainage of condensate water, possibly due to a clogged drain pipe or misalignment.
EB: Voltage Issues
The unit is detecting voltage that’s either too high or too low for its safe operation. This could be a household electrical problem or an issue with the unit’s power supply components.
EC: Refrigerant Leakage Detection
The unit has detected a potential refrigerant leak. This may impact cooling performance and can be hazardous.
ED: Defrosting Sensor Malfunction
The sensor responsible for detecting frost build-up on the evaporator coil is malfunctioning or not reading temperatures accurately.
EE: Outdoor Temperature Sensor Error
The sensor that reads the outdoor temperature is malfunctioning or has a connection issue.
EF: Indoor Temperature Sensor Error
The sensor that reads the indoor temperature is either malfunctioning or not connected properly.
EG: Humidity Sensor Error
The unit’s humidity sensor is not functioning correctly, leading to potential inaccuracies in humidity readings and control.
EH: Non-Volatile Memory Error
The unit’s memory, where settings and operational data are stored, is experiencing issues or corruption.
EI: PCB Malfunction
There’s a malfunction or communication problem with the Printed Circuit Board (PCB), affecting the air conditioner’s operations.
