What to do if Honeywell Controller Status/Alarm LED stays on after starting?
- AAshley OrtegaJul 25, 2025
If the Status/Alarm LED on your Honeywell Controller remains lit after powering up, it could indicate a hardware problem, a fault in the application, the controller starting without an application, or the operator manually stopping the application. Try powering down the XCL8010 and then powering it back up. If the problem persists, check and reload the application. If the issue continues even after reloading the application, the hardware may need to be replaced.
