1. Change the AC remote batteries
Remove the back cover from the remote control and replace all of the batteries. Try using new batteries again. When battery life on a system remote control runs out, an alert appears on the screen. The symbol means that new batteries are required.
2. Check if batteries are installed properly
If your remote won’t turn on, double-check its polarity. If your remote won’t turn on but the battery terminals appear to be in good shape, inspect the polarities. Examine the polarities inside after removing the rear cover. The “+” and “-” imprints are usually visible or embossed on them. Remove the batteries and replace them with the correct polarities indicated within the battery chamber.
If the batteries still won’t work after you’ve inserted them correctly, there might be dirt or a blockage between the batteries and the metal contacts. Remove and clean any debris from the contacts using a cotton swab dipped in isopropyl alcohol if the back cover doesn’t start working again after inserting new batteries.
3. AC remote sensor blocked
If dust is on the sensors of your remote control, it might cause transmission problems. If necessary, clean the sensors on your remote control with a wet cloth. Another frequent reason for remotes to stop working is moisture. Your remotes may be damaged by spilled drinks or other liquids.
4. Check the AC remote control settings
Accidentally pressing the wrong button on the remote control might cause a slew of issues, such as if the system shuts off due to motion-detection features. If the remote has new batteries but still does not work, try to reset the AC remote. Take a look at the product’s user guide if you saved it or find it online to learn about the remote control’s buttons and features, as well as how to use it correctly.
5. AC remote not in range
Is it possible that the remote control is outside of the AC unit’s range? If you aim the remote control at an AC system and push the ON button but get no response, you may be too far away from the AC unit. In certain situations, a minimum sensor distance of 18 feet or less is required. Moving closer to the device try turning the AC on.
6. Check the AC unit
Check whether the remote control is at fault or the AC unit is at fault. To do this, press the buttons on the AC unit to manually check if they work. If the AC works when pressing the buttons on the AC unit, then the remote control is at fault. Change the batteries, or purchase a new universal remote control for your AC unit. In the meantime, use the buttons on the AC unit to turn it ON. Once you get the new AC remote, you may need to set it up to work with your AC unit. AC universal remote control codes here.
7. Reset the AC – Restart the AC system
Turn off the main electrical breaker that powers the AC to attempt to reset the entire system. For a complete reset, leave the AC turned off for 30 minutes. After 30 minutes, turn the power to the AC back ON. Test everything and see if the AC remote is now able to control the AC unit.
