Concord 90 plus high efficiency furnace
For past few days home temperature drops down approx 6-7C degrees at night so I checked the furnace which gives me sometimes (6) LED signals other times (3) LED signals. I followed the back panel instructions also drain out water from tube connecting to motor and restart, however each time it lasts for an hour or so and dies out again for next cycle. Please advise.. Thx

This worked, we drained the tube and the furnace came back on. Although, the tube keeps filling up and then it shuts off again, we have to figure out a way to make it keep draining.
