Fault Details:

• The flame detector signals flame before combustion starts.

Recommended Solution:

1. Inspect the air intake and exhaust systems for blockages, sharp bends, or kinks in the hoses.

2. Check fuel line connections for damage.

3. Test the fuel pump by applying 12 V to the pump pins in 1-second intervals; listen for clicks.

4. Inspect the glow plug for damage, cracks, or carbon buildup. Check cables and plugs for oxidation.
