Before you start worrying about expensive repairs or replacements, you can try several easy and economical solutions. This comprehensive guide will explore common reasons why your aircon remote control may not function and provide seven practical ways to troubleshoot and fix the issue.

How to Repair Aircon Remote Control Not Working?

When your aircon remote control stops working, it can irritate you big time. This aircon remote control troubleshooting guide will help you identify and resolve potential issues with your aircon remote control. Read the following tips if your aircon remote control spot working:

Check the Batteries

Dead or low batteries are among the most common and often overlooked reasons for a malfunctioning aircon remote control. Over time, batteries lose their charge, affecting the remote’s ability to transmit signals to the aircon unit. 

Start by replacing the batteries with fresh ones and ensure they are the same type as specified in the remote’s instructions. Furthermore, consider using high-quality rechargeable batteries to save on costs in the long run. If you can decide based on the current and voltage rating of the batteries, it is the best in this regard.

Verify Line of Sight

Aircon units typically use infrared signals to communicate with the remote control. Ensure no obstacles block the line of sight between the remote and the unit. Clear any obstructions, and make sure the remote is pointed directly at the aircon’s receiver. Sometimes, a simple adjustment in positioning can create a significant difference. Moreover, check for reflective surfaces in the room that might bounce the signals away from the aircon unit.

Clean the Remote Control

If you feel my aircon remote control not working, dust and dirt accumulation on the surface and inside the buttons are the most likely issues. Clean the remote with a soft, lint-free cloth to remove debris. 

Pay attention to the areas around the buttons where dirt accumulates. If necessary, use a cotton swab dipped in rubbing alcohol to clean the area around the buttons. Be cautious not to let liquid creep into the internal components, and allow the remote to dry before using it again.

Reset the Remote and Aircon Unit

If the above steps do not resolve the issue, try resetting the remote control and the aircon unit. Unplug the air conditioner from the power source, wait for at least five minutes, and then plug it back in. 

Simultaneously, remove the batteries from the remote control and press all the buttons to discharge residual power. After a minute, reinsert the batteries and try using the remote again. This process can often clear any temporary glitches in the system.

Check for Signal Interference

Electronic devices and appliances transmitting or emitting infrared signals can interfere with the communication between the remote control and the aircon unit. Identify potential sources of interference, such as other remote controls, fluorescent lights, or direct sunlight. 

Minimize or eradicate the effect of these sources to improve the remote control’s performance. If your home has a lot of smart devices, they might also operate on similar frequencies, so consider temporarily repositioning or turning off these devices.

Examine the Remote Sensor on the Aircon Unit

If your aircon remote control not working, examine the remote sensor of your aircon. The sensor on the aircon unit that receives signals from the remote control may be obstructed or malfunctioning. Check the sensor for any physical blockages or damage. 

Ensure that no dust or debris interferes with the sensor’s ability to receive signals. If the sensor appears damaged, professional assistance may be required. Contact the manufacturer’s customer support for guidance or consult a qualified technician to inspect and replace the sensor if necessary.

Reprogram the Remote Control

The remote control may sometimes lose synchronization with the aircon unit, leading to communication issues. Refer to your aircon’s user manual for instructions on reprograming the remote control. This process typically involves pressing particular buttons in a sequence. 

Follow the guidelines carefully to reset the remote and establish a stable connection with the aircon unit. Reprogramming is helpful if you’ve recently changed batteries or experienced a power outage that might have changed the remote’s settings.


If your aircon remote control not working, before jumping to conclusions about expensive repairs or replacements, it’s essential to explore these simple troubleshooting steps. By resolving common issues like low batteries, line of sight problems, and signal interference, you can often resolve the problem without professional assistance.

In addition to the initial seven steps, consider implementing proactive measures to prevent further issues. Regularly clean your aircon remote control, replace batteries promptly, and be mindful of potential sources of signal interference. If the problem persists despite all these tricks, consulting the manufacturer’s customer support or seeking professional help may be the next step. This is to ensure your air conditioning system’s efficient and reliable functioning. Remember, a well-maintained remote control is the key to enjoying the full benefits of your aircon.
