The Universal Flame Sensor can be bent and or cut to replace over 120 part numbers for a variety of applications including furnaces, water heaters, boilers, and cooking.
Unfortunately no as the tip is where the temperature sensor is. If you cut it, it will no longer work.
Using steel wool or fine-grit sandpaper, gently scrub the metal rod of the flame sensor to remove any soot or residue. Be careful not to apply too much pressure or scratch the sensor, as this could damage it.
Question:How to adjust the flame sensor sensitivity? Answer: It can be done by adjusting the potentiometer on the board.
Adjusting Sensitivity: Locate the dial or switch that controls the sensor's sensitivity to motion and heat. Gently turn the sensitivity dial or adjust the switch. Typically, turning it clockwise increases sensitivity, and counterclockwise decreases it.
You should read a few ohms of resistance max, the lower the ohm reading the better grounded it is.
Since these sensors are designed to have a low tolerance for reading variations, they might misread from the slightest carbon coating. As most furnaces are located in dusty areas, such as basements or laundry rooms, the airborne particles can easily stick to the flame sensor, burn and cause carbon buildup.
Flame Sensor Lifespan
Flame sensors have an average lifespan of about five years. Therefore, you can expect to need to replace it at least twice before replacing your entire heating system.
Do not touch the flame sensor with your fingers. The oils on your hands can get on the sensor and make it more prone to get dirty later.
The Flame-Monitor system, being microprocessor based, requires a ground system that provides a zero-voltage ref- erence.
Most flame sensors have a coating on them to keep them clean; with this in mind, you should avoid using anything too abrasive, like heavy grit sand paper. This will wear down the coating and cause the sensor to get dirty at a more rapid rate in the future.
1. Will a furnace run without a flame sensor? No, a furnace will not operate without a flame sensor.
As the heating cycle begins, the furnace control board emits a low current voltage to the flame sensor. This is usually between 40-80 volts AC. Yes, that is correct … a flame sensor has line voltage on it during furnace operation.
This is one of the simplest furnace repairs; Oftentimes, a simple cleaning of the flame sensor will get you up and running again, however, there's much more to flame sensors than that, and while a cleaning will get you through for a while, it is a part that does have to be replaced every so often through a furnaces ...
Can you have more than one anode rod for extra protection? Yes! You can buy a longer warranty, which means the anode rod is going to be longer. And you can add a shorter rod as a secondary preventative measure.
They're often identifiable by their indentation and six-sided shape. To remove almost all anode rods, you'll need a 1 and 1/16 inch deep socket, and a strong ratchet, maybe even using a additional breaker bar to give your more leverage, although there is an easier way. Use an impact driver with the deep socket.
The anode rod attracts corrosive elements, such as oxygen and hydrogen sulfide, which would otherwise corrode the walls of your hot water tank.
Turning the power off for approximately 20 seconds and turning it back on again will reset most modern gas furnaces. Some furnace models can power on again after leaving the lockout for 1-2 hours. The cleanliness of the flame sensor of a furnace is very important.
The flame sensor rod may be malfunctioning due to the accumulation of dirt and debris making the furnace inefficient and leading to the shutdown. Ensure keeping your flame sensor clean by avoiding the accumulation of dirt and debris.
The Universal Flame Sensor can be bent and or cut to replace over 120 part numbers for a variety of applications including furnaces, water heaters, boilers, and cooking.
Having a working flame sensor is critical for a functioning furnace. While most furnaces last for 10 to 20 years, flame sensors have a much shorter lifespan of about five years. Usually, when a flame sensor goes bad, the best route is to replace it outright.
