The Honeywell Q381 Intermittent Pilot Burners provides pilot flame ignition and sensing for intermittent ignition systems. It consists of a pilot burner with a single rod combination spark igniter/flame sensor and is designed for horizontal mounted applications.
The sensor is usually located on left side but on some furnaces it may be on the right side. How the flame sensor works is by a small AC electrical charge going through the sensor and it uses the flame to carry the electrical power to ground. Burner surface to flame sensor is 4:1 ratio thus causing the AC current to change to DC current.

Nov 27, 2019· Here are the steps to test a flame sensor: Ensure the furnace is properly grounded. You can do this by powering down the heater and taking an ohm reading between neutral and the burner assembly. You should read a few ohms of resistance max; the lower the ohm reading, the better grounded it is.

Testing: To test the Flame Sensor and ensure that it is working correctly connect the VCC to a 5v power source and GND. Move a flame source with in a foot of the front of the Ir sensor and the D0LED should light up. Troubleshooting: . If the D0 …
HI All!How do Gas Roof Top Units and Swimming Pool Heaters that use Flame Sensors test the sensor itself ,this is with spark ignition and/or glow literature[Fenwal] refer to "test ports" on the spark module,I''ve never seen them! In this case a Teledyne/Lars pool heater;glow coil glows ,gas ignites for 1 then shuts down,the ...
Nov 16, 2012· First find the flame sensor. Most furnaces you will find a white wire located on the left side connecting the flame sensor to the circuit board. Watch the furnace ignite you will see spark or orange glow in front of one burner and the flame sensor should be on opposite side, but I have seen them on the next burner from the igniter.
Once removed, the flame sensor should be immediately visible, mounted to the outside of the burner assembly. It appears like a metal rod with a white or dull yellow/brown porcelain material on the mounting end, with a single wire attached to it. While some are straight, other flame sensors have a 45degree or 90degree been on the end.
Sep 10, 2021· Locate the flame sensor (refer to the furnace flame sensor location portion above) Remove the furnace access cover, which may involve releasing screws or bolts. Unfasten/unscrew the flame sensor from the burner assembly. Disconnect the wiring that leads to the sensor and control box. Loosen the screws and remove the flame sensor.
I have a York furnace, P+HED20N10001B. The main burner come on for about 1015 seconds and then shuts off. I replaced the flame sensor, Honeywell Q3400A1008 with a Q3400A1024. It still shuts off after … read more
Part No. 16091. This test unit has been designed to generate a wide range of optical output signals. Flame sensors for fire detection and flame monitoring applications can be activated and tested. Most optical flame sensors respond to Ultraviolet (UV) and or InfraRed (IR) radiation emitted from flames during combustion.

Mar 01, 2009· The pilot lights, followed by the main burner with nice blue flame. After about 90 seconds, it shuts off. If I reset it, the same thing will happen, but this time the main burner will shut off in about 20 seconds. I removed the pilot ignition and sensor (honeywell Q3400A1008) because I thought it might be dirty, (I don''t have a volt meter).
Q3400A IgniterFlame Rod Assembly APPLICATION The Q3400A IgniterFlame Rod Assembly replaces the original igniterflame rod assembly in the Q3450 and Q3480 Pilot Hardware used in the SmartValve™ System. The Q3400A has a unique keyed plug connector that will only fit the SV9501/SV9601, SV9502/SV9602, SV9540/SV9640, and SV9541/SV9641 Systems.
Sep 21, 2020· Flame Sensor. The flame sensor easily detects fire or flame of nearby materials. These detected signals are passed to the connected control devices. It is used in industrial areas for an alarm system, natural gas plant, fire suppression system and Arduino based design fire detector project.
