Hello,

My air is not working. The thermostat is set to 77 degrees and it is 80 degrees in the house. I have turned the breaker off and back on. The fan on the unit outside the house is running, but cool air is coming out, not warm as I expected.

I turned everything off for 2 hours to see if it had frozen up. When I turned it back on, it clicked and sounded like it was coming on, but didn't blow anything out. The black foam pipe coming out of the air handler is cool and I can hear what sounds like a bit of water whistling as it runs through. The tile in front of the return air vent is very cold. The filter is clean and there is no water back up in the auto shut off floater.

Any ideas of what else I can check??

Thanks so much!

If no air is coming out the vents then the inside blower motor is not running. Open unit up and with a stick or screw driver spin the fan and see if it continues to run. If it does the capicator is bad. If not move the fan back and forth. Is there a lot a play.If so motor is bad. Does the fan move smoothly or is it rough? If rough motor is bad. Also could be the fan relay. Post back with results. Good Luck

I found where the fan was located. I can spin it both ways and there does appear to be a lot of play in it. It moves smoothly, but won't continue to run. How would I tell if it's the relay or if the fan is bad? If it helps, the numbers are BAYHTR1405 AND TWE060C15FD0.
Thanks for your help Doug.

When you were spinning it did you also push in or put some duct tape on door switch? I should be located on side and pushes in when the panel is on? If it's not pushed it you will get no power to the fan.

Doing so with the relay on a circuit board is a pain without a voltage detector.

To do simple checks like this you do need some tools. A test light, a meter, or a voltage detector might be the best place to start with. I came across the niftiest gadget for trouble shooting, a voltage detector. They work through the insulation of wires. There are several brands. I have a GB Instruments GVD-505A, less than $15 at Home Depot. Touch it to a hot wire, and the end glows red. Find the doodad that lights it on one side, and not the other, and you have the culprit. You do not have to open up housings and expose electrical contacts. You are looking at where your hand is, not where the meter is. Most people are capable of doing repairs and will get it going and not get hurt if they use a little sense. The voltage detector makes it even easier.

With the system on and calling for A/C, touch the voltage detector to the bundle of wires going to the motor. If it lights, the relay is sending power to the motor, and the motor is bad. Be careful of false positives if it is a 240 volt motor and a single pole relay. You may need to hold door switch in too while you are making the tests.

Doug,

Thanks for getting back to me. I didn't think of a door switch, but it makes sense. I just looked and don't see one on either side. How can I find it. I have the top, front panel off where the fan is located.

Well some units do not have them. Mine doesn't but I thought most Trane did. If it has one it will be a plunger type that pushes in where the panel would make contact. Do you have and know how to use a meter? If no meter You could make a jumper cord to see if motor wis good or not but you have to be extremely careful as you are dealing with electricity that can hurt you. WORK SAFE!!

I don't see anything of the kind, so I guess it doesn't have one. I don't have a meter or, unfortunately, know how to use one. I have a call in to an A/C company who can come out tomorrow. It's just that it's very hot in FL right now. Tomorrow seems a long way away. I guess the best I can hope for is a relay switch problem. I'm sure replacing the fan would be quite pricey. It's just strange that it stopped all of a sudden this afternoon. The unit is only 7 years old. My last house had a Trane and it was still going strong at 13 1/2 years.

Jana

They work fine one minute and not the next. Unpredictable. If the relay is independent it's not so pricey but if it's in a circuit board another story. Hope they get you going and you're cool soon

Thank you very much for all of your time!! :)

Yeah, I paid $300 OTC for a board when my furnace blower relay died.

If you have a door switch, the outside fan likely won't work with the door open.

Most newer electric furnaces don't have door switches, My guess is it's probably just a capacitor, maybe a fan motor. Just an idea, switch the Auto/on switch on the thermostat to the "ON" position, does the fan come on?

Doug,

I just wanted to let you know that it turned out to be a wire that had come disconnected from the fan. The A/C guy reattached it and all is well. Not bad, $70 service call. Thanks again! Jana

Great. You came out all right then. Glad you're back and cooling again. Come back to this site again when you need help or just to browse.

I'm having a problem I have the air handler hooked up but my out side unit won't cut on an my thermostat is flashin cool on now the air handler comes on but won't kick on the out side unit for air or heat can anybody tell me what the problem is

I'm trying to find out if I'm hooking something up wrong because my thermostat is blinking cool on but my outside unit is not coming on
