Initial Troubleshooting Steps For Fl Error

Always turn off your air conditioner before you start fixing it. Working on an active unit can be dangerous. Make sure you disconnect the AC from the power supply. Wear safety gloves and protective eyewear to shield yourself from any potential harm. Notice any strange noises or smells when you approach the unit. These signs can help pinpoint the issue.

Inspect the drain pan and line next. Remove any visible blockage. A stiff wire or special brush will clear the line effectively. Take care to not damage the components. Regularly performing these tasks will keep the system running smoothly.
