Look close at igniter and see if maybe there is a burned spot or crack, It should be ohming between 50 and 90.
You are correct.That is what the manual says. That sure seems low for an igniter, but looks like according to Lennox specs, it is within range.Silly question, but this new board is the recommended replacement right?
I am wondering if maybe you have to replace Lennox' low ohm igniter when using this board.I did find this in the installation manual for the board
That appears to be the silicone igniter, Perhaps doa board.I am going to open this to other experts who may have other suggestions.
Hello, those transformers are rated at 24 volts AC... 28 volts ac well in range, it varies with the primary voltage, 208 to 240 volts and voltage fluctuations on the utility grid.
That variable will not affect your situation, the incorrect board or igniter will of course.. stay in touch as needed.
I will be here, good luck with it.
