The star of this project is this flame sensor module.

. The Basics of Flame Sensors. Here the Arduino Uno board. This sounds like a flame sensor issue see attached pic for typical yours may not be bent. This 3-pin flame sensor module includes different components like phototransistor trimpot LM393 power LED and output LED.

Step 1 Flip the circuit breaker switch that corresponds to your Lennox furnace to the. To achieve this connect the flame sensors to the Arduino. This module contains a phototransistor and signal conditioning electronics. Then click the sensors pins to the Arduinos pins.

I have a Frigidaire Furnace model FG6RA-096C-16B with a blinking yellow low flame sensor signal light on the module. A phototransistor conducts more electrical current when. Here we need to wire the flame sensor to the Arduino. Flame rectification is actually quite simple.

Finding and cleaning the flame sensor in a Lennox furnace is a simple repair that takes just minutes. The flame seems quite normal. The ignition control sends a small electrical current in AC alternating current to the sensor. This current is able to travel through the flame due to.

Low flame sense current is often caused by carbon deposits on the flame sensor a poorly grounded furnace or a misaligned flame sense probe. Touch the probes of the multimeter volt-ohm meter to the sensors wire ports. All flames have certain characteristics in common that include. The flame sensor is a safety component of a furnace located on the interior of the burner assembly.

The device should read a low resistance. Press the open end of the flame sensor against a. Production of by-product of. It monitors and verifies whether a flame is burning inside the unit.
