Coleman gas furnace model#DGAA077BDTA having multiple trouble codes flash, but here's what its doing; system works fine self ignitor switches on the gas switch clicks on the gas ignites stays on for about 40-60 seconds then gas switch clicks off flame goes out fan stays on code flashes 4 then 6 flashes then stays on solid.
Still running the furnace then turns on ignitor 10 seconds then gas switch clicks on gas ignites stays burning 40-60 seconds then gas switch clicks off flame goes out code flashed 5 (sometimes 1) but this is always the same pattern.
