What should be checked if the LFL 1.333 control box does not start or the gas pressure switch contact remains open?

Verify power and fuel supply, and ensure the unit is not in safety lockout. Check that terminal 1 is powered, the air damper is closed (11 to 8), the air pressure switch is at rest (12 to 4), and the gas pressure switch is closed (4 to 5). If the gas contact is open despite normal pressure, check the gas filter and pressure switch settings.
