Question about York Yankees Bedding MLB Comforter
I have a York high efficiency furnace that is not firing all the the time. The unit is about 4 to 5 years old & has been doing this for a few months now and getting progressively worse. (model # GM9S08B12DH11G) The trouble code light inside is blinking a rapid red, indicating a Twinning Error, Incorrect 24V Phasing.
Has anyone worked on this furnace because the error would indicate that the positive 120 volt and the neg 120 volt is swapped , these units will also do this when the ground wire to the furnace or gas valve or furnace or @ the panel is lose , corroded , or missing , the gnd must be present to open valve , I am aware that ac is is not usually polarity sensitive but in this case it most certainly is ...have seen many time and know it to be true
