Trane xv90 furnace heat exchanger
There are other dealers out there that would probably honor the 10 year parts warranty, do you have the labor warranty too? Hi I've posted here before just in another catagory. Love the site. I've got a Trane XV90 furnace, it was new in '04. I got a complete system: furnace, 14i cooling system, humidifier and air cleaner. The problem I'm having is I have water leaking out of what I was told is the heat exchanger. All lines coming out of the system are clear. There is rust all across the bottom of the exchanger, but still feels solid, not rusted through. I want to know the severity of this and if a do it yourselfer can do the repairs. I know it's under warranty but the dealer I got it from is total jerk. Thanks in advance for any input! Dan No, That's why I'm looking to do it myself. My neighbor does heating and air but he's pretty busy but would help if he could. Thanks, I will recheck the lines and I think I know the trap your talking about. I pulled a elbow and looked back into what i believe is the exchanger, there is alittle water in the tube that comes out but the water is below that and doesn't seem to be able to drain from there. You have a 90% efficient gas furnace, which means the furnace cools down the combustion gasses and condenses the water vapor produced by burning gas into water to increase efficiency. That also means that the furnace has a plumbing system to deal with the water that's produced, which can be 2-4 quarts per hour if the burners are operated continuously. If the drainage system of the furnace gets plugged up, you start getting water coming out of varying places in the furnace. Before long, the furnace will quit running because the furnace is plugged up. You need to check all the water lines coming from the furnace carefully to identify any that are plugged up, often with mold. In particular, there is usually a plastic trap in the furnace which commonly gets plugged up and needs to be cleaned. The problem is unlikely to be in the heat exchanger itself. The heat exchanger is just where the water accumulates when it can't drain out of the furnace. I take it from your comment that you have checked the drain lines out of the furnace carefully. If that's the case, I'd look for that plastic trap, which may well be what the plastic hose connects to. If you have a hose with a nozzle on it, that can be an effective way to clean the trap, but use any method that works including blowing through it to get rid of the mold and such. Probably a fairly easy job, I would guess. If you have a heat exchanger failure it can not be done under any type of warranty by a homeowner. It should also NEVER be replaced by DIY. You are dealing with the item that separates the fire and flue gases from the air that circulates through the home. I have seen 2 (only 2) of those trane 90% heat exchangers fail in a way in which you describe. The water and corrosion you see at the bottom of the heat exchanger face plate may be caused by a leak in the cold end header of the heat exchanger. What I see fail a lot more than heat exchanger that can produce a similar concern is the inducer receptacle cracks and leaks condensate. If you post the model number of your furnace I can give you this part number. THank you. I'm pretty good at working on things, but I know this could be something not to mess with. Your information was just what I looking for!! Model #TUY080R9VW1 (3423WU67G) Ser.#3423WU67G. Not sure if ones in brackets are necessary but put in anyway. You guys on this Forum are great thanks. you missed a character in the model number. According to your serial number your model # is TUY080R9V3W1. The receptacle: Part Item Number RCT00084 Description RECEPTACLE; TRANSITION INCLUDING FOUR MOUNTING SCREWS Hi You are correct I missed the (3) some how. Must be my high speed one finger typing. The information will be very helpful. Thanks Alot! Have I missed something? Have you and HVAC Tech figured out the problem? I don't know if we figured out the problem, but it gives me a possibility that others haven't come up with. I just have get it checked out. HVAC Tech suggested that in no way should a DIYer do this work. Thanks all Hi everyone, I apologize for not giving an update after recieving all the help, but I've been kinda busy. The problem with my furnace was the secondary heat exchanger and also the part that hvactechfw told me about. They were both cracked, the secondary had large spider web cracks. It was pretty bad, you see light through the cracks. it's fixed and all is well. It difinitely wasn't a job for a do it yourselfer. Thanks for all the help. Dan I have condensate leaking problem on Trane XV90, I replaced the Receptacle Transition (RCT00084) which indeed did have cracks. After reassembly problem still persists. I again removed inducer and poured water in rectangular opening and found leaking. Two hours later I have the tray removed which sits behind the front panel of burner tubes. I found that it also has cracks I leak tested the assembly out of furnace. I can not find a part number for this, the only number on part is 21D340235 P0 I need that part and a new fiberglass gasket for front panel. Where can I get parts, and part list
