How do I know if my flame sensor is bad?
A flame sensor is used to detect the presence of flames within the combustion chamber of a gas burner. It consists of two contacts that are connected to a circuit board. One contact is connected to ground while the other is connected to the positive terminal of the power supply. When the flame is present, the current flows from the positive terminal to the negative terminal. A flame detector measures the voltage difference between the two terminals and turns the gas on or off accordingly.
