Description
The Emerson 790-820A1 is a flame sensor for gas-powered furnaces and HVAC systems. Because it can identify flames, it is essential to safe operation. When the sensor comes into contact with the heat of the flame, it produces a tiny electrical current. The furnace control board receives this current signal and confirms that a flame is present before approving the furnace’s safe operation. Operating within a standard ambient temperature range of 40°F to 90°F, the Emerson 790-820A1 is compatible with a wide range of furnaces and can tolerate temperatures as high as 2200°F. It uses 120/240VAC as standard voltage to function. All things considered, this flame sensor guarantees the effective and safe operation of your gas furnace.
