Sure thing! To troubleshoot the Fire-Lite REL-47K, start by checking the power supply to ensure it’s providing the correct voltage. Verify all connections are secure and there are no loose wires. Next, inspect the device for any physical damage or signs of wear. If everything appears fine externally, try resetting the unit by power cycling it. If the problem persists, it might be a deeper issue with the internal circuitry, and you may need to contact technical support for further assistance or consider replacing the unit if it’s out of warranty.
