I have a Trane XE 800 Air Conditioner (approx 15 years old.) About 10 days ago it stopped running. The copper tubing leading into the house is not cool or forming condensation. It appears that the unit does not have power. The circuit breaker in the house breaker box was not tripped but I reset it anyway. The Air Conditioner is paired with a Trane XE 800 Heat Pump (separate unit) that handles the first floor and is working well. I checked the upstairs thermonstat which controls the AC unit and the furnace - the furnace comes on when the thermostat is in "heat" mode.
All work to be done by licensed professional. WE KEEP GOING UNTIL YOU HAVE THE INFORMATION YOU NEED, I come and go. This is step ONE.Hello. welcome to Just answer ! Tell me how many units sit outside the house.. and if you have cooling in either of the upstairs or down stairs units.Tell me if the fan on top of the outside unit runs when you set any of the thermostats in heating mode. or cooling mode.We can go from there.
Two units are outside the house. The heat pump which handles the first floor is operating normally, (ie cooling first flr.) The AC unit handles the upstairs and will not come on - no fan, no noise. Also the fan does not more when I switch the thermostat to heating mode.
Hello again, thanks for the data.The upstairs unit is off on one of its internal safety devices, or has blown one of its tiny fuses inside the unit on one of its computer control cards...its not something a home owner can fix or diagnose as a rule.You can try turning the the thermostat off, waiting 10 minutes and then turning the thermostat back on again. Thats called a 'soft reset'... that has about a 10% chance of working.Let me know how that goes. If you can tell me which direction you are in from the center of the nearest city i can locate some local Trane service people for you..
I'll try the soft reset. Would this condition occur if the system ran out of the R-22?
I'll contact a local technician in the morning. I had a bad experience with the local Trane rep a couple of years ago. Any idea how expensive this will be?
Thanks for your assistance.
Hello again, yes the condition would occur if it ran out of R 22 refrigerant, or if the fan failed it tripped the high pressure cut out, or if a fuse blew in one of the control cards..or if one of the control cards failed or the compressor failed. There are 6 or 8 common reasons and a few more less common reasons.The service call will generally run $150 or so, that should include a written estimate for repairs and a 60 day warranty on the repairs... **be sure you have the technician physically show you the defective part... write down the name of it in detail... tell him you need that data in detail for the technical people who advise you. Get as much data as you can, including anything amiss in what he says. Get back to me, and we can discuss it, the price and the warranty etc.If you wish you can rate my service to you so far, that way you can stay with me on this on the same dime so to speak, for days or weeks as the project unfolds, all on the same dime so to speak.
