I have an XL80 Furnace and a XL20i A/C. My Comfort Link II Control started to flash a red light and display an error code of 26. I just want to know what the error code means. My owner's guide states you have to go to document 18-HD32D2-1/69-2009 to get the answer.
Can anyone help? I will contact the dealer on Monday but it is 20Ί outside and would like to know where I stand for the rest of the holiday weekend.
