After staying half the night reading and watching videos I guess the red light is normal. I always thought that a red light meant something was wrong. I turn on my heater hear it kick on and see the flames come on when it's dark. I do see the red light blinking much faster when it's on since it's calling for heat. When the system is off the red light keeps blinking but at a slower pace.
Just got scared I screw something out when I cleaned out the filter to this heater. Plus I'm a new homeowner with this big system I need to learn.

it’s a diagnostic light. Slow steady is normal. Fast steady is a call for heat. If there is a problem it will flash a code. For example 4 flashes pause 4 flashes is telling you what the problem is. Codes will be on the board the light is on. “4 flashes= pressure switch problem “. I made that up, I don’t know what 4 flashes means for your furnace

Thank you for letting me know. I even today after I felt better figuring it out I still took out the paperwork that was left and notice the error codes. didn't say the red light would always be blinking. I did count to make sure it keep blinking without a pause. I did see other videos on how it should show when there is any issue.

Thanks once again, and happy holidays.

If it does ever quit on you come back with the fault code. Lots of great folks here to help
