Several issues can cause a split AC controller to malfunction. Here are some of the most common problems: 24 Hvac Service Near Me Air Conditioning Repair Companies Near Me Heating And Ac Service Near Me

1. Dead Batteries: This is the most frequent and easily solvable issue. The batteries in your controller can drain over time, rendering it inoperable.

7. Controller Not Paired with AC Unit: Some AC units require pairing with the remote control. If the pairing is lost, the controller won’t work.
8. Obstruction of the IR Signal: Anything blocking the line of sight between the controller and the AC unit’s receiver can prevent the signal from reaching the unit.
9. Faulty Receiver in the Indoor Unit: Sometimes, the problem isn’t the controller itself, but the receiver in the indoor unit. This is less common but can happen.
