Buy on Amazon

If your furnace starts up when the flame begins and the furnace shuts down, it’s the flame sensor. It measures 2 1/8" from mounting base to flame sensor tip. The ceramic part on this is a bit longer than the original, but the insertion depth is an exact match. It fits perfectly and installed without any difficulty. The replacement is as simple as disconnecting the wire, removing a retaining screw, removing the old sensor, and then the reverse for the new sensor.

The rod itself is 1-1/2" while the ceramic part under the flange (that gets inserted and is connected to the rod) is 21/21/minute current. These operate at very low current so rust stains likely short out that minute current.

Best designed Flame Sensor: LUXRILIX old Furnace Flame Sensor

Buy on Amazon

This after-market replacement part is made from high quality material and well-tested by manufacturer. The flame sensor makes use of the fact that the ionized flame in the furnace is a conductor, and when the current loop between the sensor and the burner is closed by the presence of a flame, a very small current ( micro amps) can flow. When rain or snow or condensation is sucked into the combustion chamber, it speeds up the corrosion process on the sensor, and this does not only affect the metal rod, but also the other end with the connector.

The sensor does not detect the flame gas valve is closed to prevent gas from flowing into the home. The dimension is 5.1inch x 3.1inch, convenient to assemble, and save your time and money. The controller will shut off the flow of gas right away if it does not detect the flame.
