SYMPTOM
FAILURE MODE
ANALYSIS
Flame Detection is
out of Sync
• Flame detection is present when no
visible signs of a flame exist
• Lockout: 105, 158
• Verify supply voltage for proper polarity.
• Check external wiring for voltage feedback
• Check internal wiring for proper connections
• Check the flame sensor and verify that it is clean
• Replace DynaFlame Controller, if necessary

Screen
• Blank display screen • Check wire connections from DynaFlame Controller to
touchscreen display
Internal Fault
• Lockout: 3-46, 58-60, 97-99, 143-
148
• Reset SOLA,
•
If fault persists, replace SOLA
