Fault 1326: Fuel Not Detected During Ignition
Burner State = Spark Ignition OR Main Ignition & Low Fire Nozzle psi < 50psi for 1.5 seconds
(continue timer from start of Spark Ignition through Main Ignition)
Causes
Troubleshooting
Fixes
• Clogged fuel filter.
• Replace fuel filter. Part #10054
• Low fire solenoid disconnected/
faulty.
• Connect/Repair/Replace low fire solenoid.
• Safety fuel solenoid
disconnected/faulty.
• Connect/Repair/Replace safety fuel solenoid.
• Faulty low fire nozzle pressure
sensor.
• Swap with high fire nozzle
pressure sensor.
• Replace nozzle pressure sensor.
Part #32982
• Loose set screw on fuel pump
shaft coupler.
• No/Low fuel psi with fan
turning.
• Tighten set screw.
• Restricted fuel flow through the
low fire and safety fuel solenoid
valves.
• Inspect fuel paths, check for
overtightened fittings. See Test
1001.
• Remove restrictions.
• Clogged fuel lines.
• Use compressed air to clear the lines.
