Hi, I have one of these furnaces and it stopped working yesterday. I have tried everything to reset it and they didn't work. Today I went up in the attic and checked the LED lights and they were flashing to indicate;
1.Improper main ground
2.Broken ignitor; OR: Open ignitor circuit
3.Line voltage below 75 volts
It has been working fine for quite a while...
I did let the filter get pretty dirty and a friend said it is likely one of the sensors got dirty as a result. My question is which one and where do I find it?
(I have replaced the filter and need to get it turned back on ASAP)
