Why does my CLEAN BURN CB-3500 Burner shut off on reset within 15 seconds?
- KKelly PenaAug 14, 2025
The CLEAN BURN Burner might shut off on reset within 15 seconds due to: * A fuel delivery problem. Follow the procedures listed for a fuel delivery problem. * A dirty cad cell. Clean and check the condition of the cad cell and cad cell wires. * Loose cad cell wires. Check that the blue and black wires are connected properly into the primary base (terminals 11 and 12). * Damaged cad cell / cad cell wires. Replace the cad cell and cad cell wires. * The primary control not receiving the proper µA signal from the cad cell. The photo current is measured with a direct current ammeter in series with the photo unit (+ pole on terminal 12). With a flame, cad cell current must be between 50 µA and 210 µA at 240V. With no flame, the measured photo current must be maximum 5 µA at 230V.
