Compressor fan motor runs backwards

Trane XE1000: Fan on outside compressor unit runs backwards, even with thermostat switch set to 'off'. Doesn't stop until circuit breaker is switched off. IF A/C is turned on, fan will reverse to proper direction but runs at reduced speed. Just started a few days ago. Any ideas??

    Thanks for the help, folks! I just installed new capacitor, but no change. Motor still runs backward even if heat is selected on thermostat. No apparent wire problems and compressor relay at condenser unit moves freely. WHat next??

  • danhark May 12, 2009

    Fan motor is completely sealed, so can't see anything. It's a GE D14407P01, if that helps. Spins freely, has about 1/4" play along thrust axis.

  • danhark May 12, 2009

    Latest update: replaced thermostat - now fan runs backward if heat is selected, doesn't run otherwise. If A/C is selected, compressor runs, but no fan.

  • danhark May 13, 2009

    Rechecked t-stat wiring, OK. turned furnace circuit breaker off, then on, and all was well inheat mode, went through a normal heat cycle ok. Switched to cooling, fan came on at proper time but at reduced speed. when cooling shut down, fan runs in reverse again and can only be stopped by tripping A/C circuit breaker. Resetting furnace CB didn't help this time. Is this a problem with the control board at the furnace??

  • danhark May 13, 2009

    Nobody has worked on the system for several years, which was when I changed the start/run cap because the fan wouldn't run, and all was fine until 5 days ago. We've had lots of stormy weather for the last month, but I can't confirm lightning or surge damage as no other equipment in house seems affected. Just a thought....

  • danhark May 13, 2009

    Finally broke down and called A/C tech. Turned out to be the fan motor, as originally surmised. I'd still like to know why there's power out to the unit with everything turned off.

    Thanks for the help!!!

    I, too, would like to know how that motor was running "on its own". Maybe you should keep the old one -- it might reveal a secret source of free energy.

  • Samuel Charles Spriggs May 11, 2010

    It sounds like the tstat is properly connected since you didn't replace it until this symptom appeared -- the old tstat worked properly at one time -- correct?

    Given that, I would suspect the controller. Sounds like a crossed wire since the controller is just a bunch of connections among the tstat, a 24VAC transformer, and relays. Has anyone worked on the controller lately?

  • Samuel Charles Spriggs May 11, 2010

    If I understand correctly, the A/C compressor fan outside runs when the thermostat is set to heat? This should not be happening -- there should be no current going to that motor unless the thermostat is in cool mode. Am I getting this right?

    I checked for the motor on the internet to get specs -- couldn't find it.


  • Samuel Charles Spriggs May 11, 2010

    Does this motor have a centrifugal start switch? Do you see a little gizmo inside the motor on the shaft -- like some electrical contacts with springs on them?

  • Samuel Charles Spriggs May 11, 2010

    Probably a bad start/run capacitor.

    Do you want to troubleshoot and try to fix?

Outside Air Conditioner Unit: Fan Spinning in Reverse

Recently I replaced the contact relay and the capacitor (dual capacitor) on my 2.5 ton Payne outside unit. I thought that I wired everything on to the new capacitor correctly by following the wiring on the old capacitor. However, when turning on the unit, the fan on the outside unit spun counterclockwise. The unit was Sucking In Air rather than blowing it out, which is bad for the unit.

Solution: Originally on my unit the Brown Fan wire went to the Fan position on the old capacitor. The other Light Colored Yellow Fan wire went to the Common position on the old capacitor. However, wiring it the same way on the new capacitor reversed the rotation of the fan, thereby causing the unit to **** In Air. By reversing the Fan Wires on the new capacitor, the fan spun clockwise and the air was blowing out of the unit. On the new capacitor the Light Colored Yellow Fan wire was this time connected to the Fan position of the new capacitor and the Brown Fan wire was connected to the Common position of the new capacitor.

Note: If your compressor has a delay in starting, you may want to consider adding a hard start capacitor. This has two Black wires that are wired to the Compressor position of the capacitor and the Common position of the capacitor. Wiring order does not matter.

My Gibson seemed to have that 'free energy' aspect too. Except it always spun counter-clock-wise (how it should), but did not increase in speed when the AC turned on. Turns out there was a short from the lines leading from the capacitor to the fan. The cables were not threaded properly under the lid and fan, so the lid sawed one of the cables, cut all except for one strand and dug it into another wire. Turns out the 'free energy' was just the circuit being completed by the peeled wire. My short was easy to spot, but if the circuit is completed somewhere inside the fan motor it will take a lot more work finding.

Most likely a bad motor or bad capacitor. I would check the capacitor first as this is probably a $20 fix. The fact that it runs in the correct direction but at a reduced speed really leans hard to the capacitor.

Good Luck and hope this resolves things for you. Let me know.

    It now seems that the t'stat is wired wrong. Please get back to me and I will do my best to get it going for you.


  • Dennis Boxerman May 14, 2009

    Even with everything turned off, power still exsists at the outdoor unit as most are wired in such a way that 1 leg of power goes through the unit to keep compressor warm. This prevents freon from being drawn out side during cold seasons but a/c is still being used as structure is still somewhat warm.

    Sorry I could not be of more help.

My Trane XB1000 is doing the same thing, it spins conterclockwise when the a/c is on and clockwise when it is off. It also does not seems to be going at full speed, it seems fast but not real fast if that makes any sense.

How much did your repair (replace the fan motor)cost if you don't mind me asking?

2002 4 ton Bryant air conditioner shuts off, fan still runs but not cooling is problem in the controls in the attic or in the AC unit or both?

With a non heat pump it is a simple 24 volt AC control circuit. In the attic there is a relay that is actuated via the fan control wire directly from the thermostat. On the thermostat there is an auto/man switch that controls the fan. Manual the fan runs all the time. Auto fan turns on and off with the outside compressor.

If the system is not calling for cool and the fan continues to run the fan relay is sticking. common problem. Sometimes after running for several days the relay will stop sticking if not, replace relay.

If the system is calling for cool and the compressor stops I would still expect the fan to run until thermostat tells the A/C to off. Some compressor units include a safety switch or high-pressure cut-out switch A blocked internal valve bad control board or external fan in outside unit defective no air flow in outside unit.
High pressure cut out not good,

Suggest turning temp max cool and observe. If acceptable cool and the compressor runs without interruption all is good, except for the blower in the attic. Safely check relay in attic blower circuit.

Hope this helps.

Cannot get ANY of the fans to work.

one half of the breaker you moved is not making contact in the panel or moving the breaker caused the fan relay to be on the same 115 volt leg as the power leg. If the breaker is connected to two points in the panel and you have 115 volts on each side of the breaker (230 volts) You can move the breaker one notch higher or lower or switch wires on the breaker to correct the circuit.

a contacter can be bad even if it is open, power still could pass through it bacause it is stuck down, breakers are the same way thay could be in off position but power pass through them always check with meter first, this happens because of heat that fuses the switch together . , parts go bad for many reason fatigue is just one of many.

Had 16 xi Trane heat pump installed 3 years ago. It ran well for the first couple of years. It began to stop heating and would blow cold air only. Have tried both aux heat and reg. heat to run and neither...

That's a complicated system that needs a qualified technician to service it. Lots of people can install them and they run fine, for a few years. Your indoor unit, operating on 2 heat elements, will feel like its blowing cold air even though its heating, just not so well. And not like you are accustomed to. Each element (5kw)=22.7amps, on average. So 3 elements operating should trip a breaker. Its probably been operating on 2 heat element plus the heat pump. And now you have trouble with the heat pump. If you can't TRUST the guys working on your equipment, try someone else. A second opinion. Normally a 3 or 4 ton unit will have 15kw heat installed, heatpump or not. 5 ton, 20kw. If yours is a 3-4ton, cooling, the 100amp(or normally two 60 amp) breaker should have been installed upon equipment change out. If yours is blowing cold all the time, something is wrong with your heatpump. The electric heat inside operates only when the heatpump can't keep up(real cold outside), the heatpump is in defrost(then it's actually in cooling mode), or if you have the tstat in aux/em. heat. Try a local trane dealer? Of a technician with 15-20 yrs under their belt. A trane dealer should have trane tech support also. BIG HELP!!!

Problem with Air Conditioner

there will be an access panel where the motor is located. 1st thing to check is fuse or circuit breaker feeding the air handler. this is on seperate power from compressor unit outside and usually has a fused or breakered disconnect on the side of the unit. if fuses are good or breaker is not tripped then switch fan mode to on. if blower runs in on but not in auto then it is a thermostat problem. if still no go then turn off power, remove access panel and find the squirrel cage fan blade. make sure it turns freely. it is very common for these motors to go bad. it can usually be removed easily and taken to a motor shop. I use Roy's Electric in Richmond, Va. They can test the motor on the bench and replace it if it is faulty.

Thermostat inside went up to 78 degrees which was set for 73 degrees. I checked filter filter was clogged. I cleaned filter. However could not get outside unit fan to go on even after turning off for 20...

Did the circuit breaker trip or did you turn it off and back on? If you had to remove the blower door to get
to the filter make sure the door is secured because
the door has a rocker switch that powers the entire unit.

Upgrade Baystat 239 to a Honeywell RTH7600D controller

For Trane sytems, B is your "Common" wire. O is your reversing valve relay, G is your fan, Y is your compressor contactor, R is Hot, Brown will not be used on your electronic tstat. X2 is your backup electric heaters. Without knowing what terminals are on your new tstat, I cannot offer more information than this. The installation manual may indicate what each terminal is controlling. I strongly suggest to write down ALL of the terminals and colors from your old t-stat and be sure to turn off the power to your air handler. Put the fan switch on your tstat to ON before turning off the power. Make sure the fan is running. Then turn the power off to your Air Handler. If your fan stops running, you have turned the power off to your tstat and are ready to start replacing it with your new tstat. I hope you find this helpful. Good Luck!!!

AC wont kick on....

The first thing to check is your breaker box. There should be one double breaker for the air handler unit, that's the inside unit, and one double breaker for the compressor, that's the outside unit. Check both breakers. If you're not sure if they've be thrown, click them toward the outside of the breaker box (off position) and then click them toward the inside of the breaker box (on position). If the breakers are on and you still are not getting any A/C take a look at your compressor, (outside unit). If the fan is running at least you're getting power. However, your compressor down inside the unit may not be getting power or it may need to be replaced. The compressor has a start-up cap. If this cap goes bad or the wires from this cap fry or corrode away, this will also keep the compressor from starting but the fan will still run. If the fan is not running it could be caused by a faulty relay inside the compressor cabinet. This relay is supposed to open and close based on a low voltage signal from the thermostat. I believe it's roughly 24 volts. This relay switches on and off the 240 volts for the compressor and the compressor fan. Often this relay goes bad or the wires leading up to it fry. If you?re going to work on the unit yourself make sure all power is shut off. There should be a shutoff switch on the outside wall near the compressor. I?d also shut the breakers off.
