Furnace burner cycling on & off
Brought home our new TT last week to prep for a combination maiden voyage and anniversary trip.
Turned furnace on, blower started, ran for a period of time then the burner lit. Placed hand over floor register and felt just a slight draft of warm air coming out. All three registers felt the same. I did the same thing when we picked it up, commented on low air flow, but guy at the dealer said that was normal they all felt that way. So OK, I thought, we bought our last trailer nine years ago so maybe something changed in furnace technology.
Well, guess I was wrong on that count.
What warm air was coming out, maybe two-three minutes worth, starts to turn cool, the blower is still running, then after a period of maybe a minute or so, I hear the burner light off a second time. The air starts getting slightly warm, stays warm for maybe 2-3 minutes, then starts to get cool again. Blower is still running, then again after abut a minute or two, I hear the burner light off again. Never had a furnace that the burner would light, go out then relight.
Something new maybe? Some new technology in furnaces to keep temperatures lower.
Two hours later, same cycle still repeating itself trailer has warmed up about 10 degrees. It was about 35 outside. No way would it keep up in colder temperatures.
Yes it's a larger trailer than what we had, but our other would warm up in 15-20 minutes, furnace running constantly and the burner would never go out.
Put thermometer in floor register and air temperature right at point of duct connection would peak out at about 120, but then would drop off.
Pulled off cold air return to check for blockage and did not see any.
Put same thermometer into duct right at furnace discharge and air temperature there reached 140 before dropping back off.
It would appear that there be a gremlin with either the burner or air flow thru furnace.
Thoughts or ideas on what else should I (we, it's going back to dealer Saturday) be looking at?
Thank you
