Common Issues and Troubleshooting for Electric Air Curtains

In recent years, with the deterioration of the Earth's environment, the frequency of global special weather events has been increasing year by year. People are increasingly reflecting on the impact of the modern lifestyle they enjoy on the environment, and awareness of energy conservation and environmental protection is on the rise. The timely appearance of electric heating air curtains not only ensures a comfortable indoor air environment but also saves energy consumption, making them increasingly popular. As a high-power device that converts electrical energy, it is inevitable to encounter various issues during use. Today, let's take a look at the common problems and troubleshooting methods of electric heating air curtains together.

1. The electric heat air curtain fails to start after being turned on

The electric heat air curtain fails to start after being turned on, which could generally be due to the following reasons: low power supply voltage; a faulty start relay in the air curtain cabinet; a damaged overload protector in the air curtain cabinet; or a damaged compressor winding in the electric heat air curtain. At this point, we should first check if the power is connected properly, and whether the plug and socket are loose; if the power indicator light is on, it may indicate a start-up issue caused by the power board. If the light is not on, it is likely a motor issue.

2. The electric heat air curtain intermittently stops and starts when blowing air

As the electric heat curtain machine is an electric heating type of equipment, the three-phase motor heater features an overcurrent protection mechanism internally. Poor contact in one phase of the electric heat curtain machine can lead to an unbalanced current or excessive current, triggering the heater's overcurrent protection and causing a power outage. If the three-phase motor heater overheats during operation and resets, it can result in intermittent operation of the electric heat curtain machine, with the fan sometimes turning and sometimes not. In this case, a comprehensive inspection of the electric heat curtain machine is required to identify and resolve the fault.

In addition to the two typical issues mentioned above, electric heat air curtain machines may also encounter various problems such as weak air output, malfunctioning remote controls, excessive noise, water leakage, and blade detachment. At this point, it is essential to trace the root cause of the issues. Basic checks include verifying that the intake and exhaust airways are not blocked and ensuring they are clear; checking if the screws of electronic components are loose and if the wiring is secure; inspecting for any loose bolts on the suspended electric heat air curtain; ensuring the power cord of the electric heat air curtain is intact, and if there is any sign of aging, contacting the manufacturer to have a professional replace it promptly. We recommend that consumers thoroughly read the electric heat air curtain manual after installation to get a comprehensive understanding of the equipment and also to refer to the manual for common fault identification and troubleshooting methods to address any issues.

To ensure the continuous proper operation of the electric thermal air curtain and to avoid unnecessary issues, we would like to kindly remind all consumers: Please do not place objects near the exhaust and intake grilles; always switch off the full-pole switch before cleaning and maintaining the electric thermal air curtain to prevent electric shock.
