The 11 Best oil Furnace sensors (2023 reviews)

The seneca river trading oil furnace sensor's material feels more premium than its price would suggest. The Rheem furnace is super touchy and eats one per season. It will fit all the Rheem rgra classic 90 plus models. It has a thin plating on it, the bi-metallic portion of a thermocouple. It is coated with impurities from the gas over time and stops "sensing" the heat properly. The tip has a coating of some sort to make it last longer.

This is just a “clean” unit able to sense the heat from the flame and give proper feedback to the furnace electronics safety system. It is the correct flame sensor for your unit. It will be simple to install.

Best For A Furnace: Part oil Furnace Sensor

Buy on Amazon

If your furnace starts up when the flame begins and the furnace shuts down, it’s the flame sensor. It fits perfectly and installs 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 ceramic part on this is a bit longer than the original, but the insertion depth is an exact match 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/. It measures 2 1/8" from mounting base to flame sensor tip. These operate at very low current so rust stains likely short out that minute current.

Best designed Flame Sensor: LUXRILIX oil Furnace Sensor

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate sensor. The luxrilix oil furnace sensor is exactly that - it's a simple sensor that hits all the right notes. 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 controller will shut off the flow of gas right away if it does not detect the flame.

The dimension is 5.1inch x 3.1inch, convenient to assemble, save your time and money.

Best Feature: Easy To Install: Stanbroil oil Furnace Sensor

Buy on Amazon

Stanbroil is known for creating pragmatic and minimalist sensor for people on the go, and its line of stanbroil oil furnace sensor definitely falls in line with that reputation. The Flame Sensor is a safety component of a furnace located on the interior of the burner assembly. It is a short length of thin metallic rod that creates a small current of electricity in order to confirm there is fire burning within the furnace. It monitors and verifies whether a flame is burning inside the unit.

The Flame Sensor is made from durable high quality wear-resist metal and ceramics. It is great as the gas valve opens to begin the combustion process, and the current is sent out from the sensor in order to detect the presence of heat from a flame. The flame sensors ensure the burners are operating properly and have ignited the gas. It is one of the most important safety features of your furnace.
