What is a Cad Cell?

A cad cell is a device found in oil burners that plays an essential role in the safe and efficient operation of these heating systems. It works by using light-sensitive cells to detect the presence or absence of a flame, allowing it to monitor whether there is a steady and controlled source of heat to power the burner.

Without a functioning cad cell, an oil burner could potentially ignite fuel vapors outside the combustion chamber, creating a dangerous situation for anyone nearby. On top of safety concerns, having dirty or damaged cad cells can also cause erratic burner behavior, leading to increased fuel consumption and decreased system efficiency.

In short, while it may seem like just another small component in your home heating system’s complex machinery, ensuring that your cad cell is clean and working correctly is crucial for both your comfort and safety during colder months.

Why You Need to Clean the Cad Cell

Cleaning the cad cell is an essential task that homeowners should undertake to ensure that their oil burner operates smoothly. The function of a cad cell is to detect if there’s any flame present in the oil burner combustion chamber, and if it fails to do so, then your heating system will not work. Various factors could prevent a cad cell from functioning effectively, including dirt, grime buildup, or damage.

Apart from preventing malfunctions in your furnace, cleaning the cad cell has other benefits worth considering. For instance, it helps prolong the lifespan of both the electronic controls and ignition systems by reducing wear and tear associated with clogged cells and also increases fuel efficiency.

With these benefits in mind, every homeowner should develop a regular maintenance schedule for their oil burner’s components. Cleaning your Cad Cell may seem like just another mundane routine chore but can ultimately make all difference when it comes to ensuring heat comfort during those chilly winter months.

How To Clean the Cad Cell

Cleaning the cad cell on your oil burner is an important maintenance task that you shouldn’t overlook. Neglecting to clean it regularly can reduce the efficiency of your oil burner and even cause it to shut down entirely. Fortunately, cleaning the cad cell isn’t difficult, and with a few simple steps, you can have it working like new again.

Firstly, turn off the power supply to your oil burner before starting any maintenance work. Then locate the cad cell assembly which is usually found near or on top of the burner unit. Ensure that all wire connections are secure before removing them from their terminals.

Next, use a soft brush or cloth to wipe away any dust or debris that may have accumulated around the optical lens and sensor area of your cad cell assembly. Be sure not to touch this small component directly as fingerprints could interfere with its function.
