Question about Heating & Cooling

1 Answer

Trane 4TTX6036B1000AA outdoor condenser, contractor doesn't engage, and when physically pressed only the compressor comes on.

4TTX6036B1000AA is matched to a XV80 furnace / air handler. I tested the thermostat via bypass and that checked out. The system is equipped with a low pressure switch but that doesn't seem like the issue. The system does have a float switch, but the pan is bone dry. The replacement motor for this unit is extremely expensive, $600-$800, I am trying to figure out what is wrong exactly, but the contractor is throwing me off.

Hi, Sounds like you have a short in the control circuit to me. Turn off all power going to the unit. Write down or otherwise mark the wires leaving the control board going to the thermostat. Remove them from the control board. Replace the fuse. Turn power back on and see if the fan still runs. If it does, check and or replace the heat limit switch that brings the fan on during the heat cycle. It may just need adjusted. If the fuse blows, I would think that the control board is probably bad. If it doesn't blow, Remove the thermostat. Leaving all thermostat wires open check them with an Ohm meter. There should be no continuity between them. Twist all the wires together at one end and ohm them again at the other end. You should have complete continuity on all wires. If the wiring checks out, down power the unit. Double check your wire colors and rewire the control board. With all wires open at the thermostat, turn the power back on. Touch the RED wire to the YELLOW wire. The Condensing unit should come on. Touch the RED wire to the GREEN wire. The fan should come on. Touch the RED wire to the WHITE wire. The heat should come on. Down power the unit. Replace the thermostat. Test unit. If the fuse has lasted ok but blows now it is either wired wrong at the Thermostat or the thermostat is bad. I hope I have helped. NOTE: If you can not understand these instructions. Call a licensed Heating / Air conditioning company. kstfas

SOURCE: Float Switch on primary condensate drain.

I think...yes. Stopping the machine before the water fills the secondary pan couldn't hurt, but don't take the secondary switch out. (Wire it in series with the primary switch.) Air conditioners get plugged up in places besides the primary drain pipe and the secondary switch wii catch anything the first one misses.

SOURCE: I have a Trane Xe-60 furnace about 19 years old.

THIS IS A COMMON PROBLEM WITH THE DOOR SWITCHES, MY FIRST ANSWER WOULD BE REPLACE THE SWITCH SECOND WOULD BE OPEN THE DOOR AND PUSH THE BUTTON IN AND SEE IF THE FURNACE WILL WORK. THIS SWITCH IS JUST A DOOR SAFTEY IF THIS WORKS. I HAVE TAPED A PIECE ON THE INSIDE OF THE DOOR WHERE THE SWITCH WILL HIT THE DOOR ABOUT A 1/4 INCH THICK AND SEE IF THIS WILL GET YOU RUNNING UNTILL YOU CAN GET A SWITCH

Trane XR12 Heat doesnt work after 15minutes of operation


Sounds to me like the outdoor unit is malfunctioning. Could be a control board going crazy, could be the reversing valve leaking. A trouble call to the local contractor is the best idea, preferably a firm that deals with your brand.

A/C compressor doesn't engage


Have you checked the thermal protector switch on the compressor? If you probe the wire with a test light and the compressor comes on replace the switch.

Ruud ubhc-17j11sfd the outside unit wont come on for AC. I checked the breakers in the main breaker panel for the house. The fan inside works.


Hi!!
Did you check if the outside fan is working?? On the summer time the failure of condenser fan motors increases due to hi temps.
Have somebody turn unit on as usual while outside you check if condenser fan is turning and if the compressor kicks in. If the fan motor do not work, the compressor will shut of to prevent damage..
If either one of them tries to start but can't take off, replace starting capacitor, some units have separate capacitors and some have combo capacitors, they work the same.
If after replacing the capacitor the fan motor still don't want to start up, replace motor. If Compressor do not want to start, call a HVAC Technician to perform further testing.
Good Day!! Don't forget to rate this post!!

I am trying to get some information on Intertherm unit on the inside of a Manufactured Home, With the new Hud requirements they are saying the out door unit must be installed by the manufactures...


Hi, since you live in a Manufactured home and not a R.V., I see no reason why you cannot go with what ever type of condensing unit you want to install on a slab outdoors. The installation instructions for the Intertherm unit for installing the outdoor unit should apply to any brand unit you want to use as long as the size of the indoor coil is the same capacity of the outdoor unit. For example, if the indoor unit is a 2 ton, 2.5 ton, 3 ton and so on, the outdoor unit would have to be the same is all. Same freon type, most are R-22, but they are using the new R-410a freon, so make sure of the freon type of the indoor coil is and get a unit of the same size and freon type. The installation instructions for the Intertherm should almost be the exact way to install any other condenser. Look for things like the distance from the outside wall, if it needs to be anchored, how far away the electrical disconnect box has to be from the unit, example 4' to 6'. Things like this you need to look for in the installation instructions is all. The new condenser unit holds enough freon for up to 25' of copper line set also. Try to stay with in that range to the indoor unit. If not, no big deal, they may need to add or remove a little freon is all. I hope this has been helpful to you on this. Trane, Carrier, Rheem, Ruud, Bryant, are all top of the line, better made then Tntertherm in my opinion. They should all be hud approved, I don't know where you are from, but here in Ca, they are.
I wish you the best, and please don't forget to rate me. I know you will be kind.
Sincerely,

Outdoor fan does not come on


most likely it the the cap that is bad. Is this in heating or cooling mode?

Compressor for air will not cycle on.


Check and see if you have a common wire on the thermostat. If you do not, then you will need to replace batteries if applicable.

If you do have a common wire, then batteries are not necessary for thermostat operation.

Even though the thermostat wires are secured properly and the thermostat worked fine in the heat mode, it doesn't mean it will work for the AC mode.

If you want to check the thermostat in an easy manner, you will need to jump out the Red and Yellow terminals at the thermostat. Be sure to turn off power first to the furnace. After jumping out, restore power to furnace. If the unit comes on, then your thermostat is bad. If the unit fails to come on, you have another issue. You can repeat this process at the outdoor unit with the low voltage lines if you feel capable. If unit comes on, your problem lies between thermostat and outdoor unit. If your unit fails to start, your problem lies within the outdoor unit.

Be sure to check any drain pans, float switches, or cut-out safeties installed that may cause this. Many contractors will wire in drain safeties to the outdoor unit to shut down the compressor in the event a drain line has clogged and backed up into the emergency pan. Of a condensate pump has failed.


If you do not feel you are capable of this, you may need to contact a local professional to come diagnose the situation. But those are a few simple tasks that you can complete yourself to narrow down a problem.

Recently installed indoor unit and outdoor unit. Outdoor unit has not been wired yet. Installer said I could use indoor unit on em heat until it gets wired. Installed one week ago, now does not work. ...


Hi, wow I can't believe they left you with E-Heat only, running the blower with the heat strips on!! Like it says, for an emergency in the event you loose you're compressor. You say that know you have nothing.I would have to be on site to wire the condensing unit, High and Low voltage as this is a heat-pump and they all have different wiring schematics. Look at the indoor unit and find the power source.Being a heat-pump you should be at 220volts. Find the box it may be right there to see if a breaker has tripped. If so, turn it off and snap it back on.If this is not the problem, you need to get on the phone and have them back on site today, and if they are Licensed a/c Contractors and refuse to come out because its a week-end, don't take no for an answer, just bring up the State Contractors License Board. They should have a tech on call 24/7 as I was one on call until I became a contractor. Again, don't take no!! Best of Luck to you,
