Reasons behind the Hisense Air conditioner E5 error

Unraveling the mystery behind the Hisense Air Conditioner E5 Error requires understanding its root causes. There are several potential culprits to consider:

Faulty Coil Temperature Sensor

The coil temperature sensor plays a pivotal role in your Hisense air conditioner’s operation. It’s like the air conditioner’s thermostat, controlling the cooling process. If this sensor malfunctions or gets damaged, it can cause the E5 error.

Disrupted Connection to the Control Board

The connection between the coil temperature sensor and the control board is crucial for the seamless operation of your air conditioner. If this connection gets disrupted or weakens due to any reason, the E5 error may be the unpleasant outcome.

Overfilled Refrigerant

An often overlooked cause is the refrigerant level in your Hisense air conditioner. If the refrigerant is overfilled, it could lead to the E5 error. Maintaining the appropriate refrigerant level is key to prevent this issue.

How to fix the Hisense Air conditioner E5 error?

Fix 1: Inspect and Replace the Coil Temperature Sensor

The Hisense Air Conditioner E5 Error is often associated with the coil temperature sensor. Thus, inspecting and potentially replacing it should be your first fix. Follow the steps below:

• Step 1: Power Off the Air Conditioner: Before starting any repair, ensure the air conditioner is powered off. Safety should always come first.
• Step 2: Access the Coil Temperature Sensor: Depending on the model, the coil temperature sensor might be located behind the filter or on the evaporator coils. Consult your manual for exact location.
