Coleman DGAA070bdta 3 flashes & 4 flashes.
What would make my furnace flash 3 green lights until the Upper limit switch is toggled, then flash 4 green lights until Upper limit switch is toggled again. Blower does come on. Does not attempt to start the ignitor.
Replaced the following this year:
025-35358-000 Upper Limit Switch (3 flashes indicated this needed to be replaced)
s1-025-35358-1000 Limit Switch (4 flashes indicated this needed to be replaced)
s1-024-27666-001 combustion air booster (pressure switch)
3 amp fuse (previous one was not broken or arced, replaced just in case)
Replaced Ignitor last year:
1474-052P Ignitor
I am not sure what to try next. I am proficient in DIY and mechanically inclined, so changing parts out is not a problem at all.
