Flame rod readings
WebFeb 21, 2024 · On Lennox furnaces with 7 segment display, you can only check flame signal from board by means of button by display. If you try and check with meter in series you're reading will be scrambled and bounce around and not be accurate. You're reading will most likely be anywhere from 10-20 uA when taken from board. Reply. WebThe cad cell in darkness has a very high resistance to the flow of electrical current. Yet, in the presence of visible light, it has a very low resistance. For a properly adjusted burner, during operation, the cad cell resistance should be approximately 300-1000 ohms, but not more than 1600 ohms.
