After a hour of rest the unit will try to restart. It will lockout after 5 tries and wait a hr and start over. Icing up is VERY bad and hard on the inducer/exhaust fan also as it sucks VERY hard and overworks it and will shorten it's life and unfortunately Trane parts are NOT cheap if you get my drift. Well built but expensive.
The reason I ask...
I bought a 6 year old house. The previous owners had the heat on all winter, but never came out. AFAIK they never had a problem with the furnace.
It iced over on me the first time we reached 0F.
HVAC guy is being reasonably cooperative (he installed the pipes too close together, too close to a side wall, too close to a deck, and the pipes are too close together) but has noted that the water heater vents near by, they didn't use it in the winter (they drained the pipes) and just maybe it is the problem.
I don't think so; they would have to be running at the same time to matter, and that won't happen much; but I can't say it isn't a factor, and would explain why the previous owner had a problem.
But if the inducer tries forever, then the first weather over freezing, the ice would melt and all would be back to normal. The previous owner would never know they had a problem. (as I said, they drained the pipes and kept a 2000 heater next to the water meter just in case)
I am working with the installer, and he has brought in the Trane rep; so we will get this fixed, it is just a matter of who is responsible. Speaking of which, the plumber put the WH vent too close to the furnace inlet and a side wall. The general contractor won't answer my phone calls. Would he be responsible for the plumbers failings, especially if he refuses to tell me who the plumber is? Thats a side issue, but maybe you know about it.
Sad thing is, there is another, closer wall that they could have used with no problems. Well, we may still be using it.
