Honeywell LG1093AA45 is a flame sensor (also known as a flame rod or flame detection electrode) commonly used in gas-fired heating systems, such as furnaces, boilers, and water heaters.
Key Features:
-
Type: Flame rod (ionization-based flame sensor)
-
Application: Detects the presence of a flame by sensing the ion current when a flame is present.
-
Compatibility: Used in Honeywell and other gas control systems.
-
Material: Typically made of high-temperature-resistant metal (e.g., stainless steel or silicon carbide).
How It Works:
-
The flame rod is positioned in the burner flame.
-
When the flame is present, it conducts a small electrical current (ionization current) due to the flame’s conductive properties.
-
The control board monitors this current to confirm flame presence.
-
If no flame is detected, the system shuts off the gas valve for safety.
Common Issues & Troubleshooting:
-
Faulty Flame Sensor: Can cause intermittent or no ignition.
-
Dirty Flame Rod: Soot or carbon buildup can prevent proper flame detection (clean with fine sandpaper or steel wool).
-
Improper Positioning: Must be correctly placed in the flame envelope.
-
Electrical Issues: Check wiring and connections to the control board.
