If the fan motors was replaced, most of them these days are reversible... if there is a shorter set of wires at the fan motor, then they need to be swapped / switched to run in opposite direction.. make sure breaker or disconnect is off..

Swap the c and f wires on the capacitor. Use caution 300+ volts. Turn power off and discharge cap with insulated screw driver, AND wait 5 minutes to touch.

SOURCE: 2 problems.. AC Comp cuts out. And Fan will not stop.

Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!

SOURCE: outside makes loud noise

I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

SOURCE: Cooling fan on Philips DVDR3576 runs on when the unit off?

I noticed the same thing on mine. I determined that the unit turns on the fan AND Hard Drive during the period of 11:59 to 12:00 BOTH AM and PM and continues to run until the unit is cycled on and off either with remote or by a program. I used a stethoscope to listen to the Hard Drive humming inside; when the unit is cycled off I could hear the Hard Drive shut down, and a second or 2 later, the fan shuts off. I had purchased several other new units thinking I would return the "defective" one. Testing them, (by setting the clock to 11:57 and wait) both other 2 units did the exact same thing. So I assume that's a software "oops" on probably all units.
My "solution" is to set up "dummy programs" to record for 1 minute after those time periods: like 12:03 to 12:04 AM and PM on a daily schedule, and I pick a channel I usually don't record. The 00:01:00 recording time and "special" channel number make it easy to quickly identify the unwanted "dummy programs" and I use the "multiple title delete" feature to periodically delete them.
So I accumulate 2 titles per day, but I prefer that to having the hard drive run all the time.
Incidentally, I talked to a sevice rep at Philips, and the only thing they could offer is to set up a return for refund. The Philips 3576H is, in my opinion, a fantastic unit and I think the little glitch is well worth the benefits of the features it provides. How did I ever live without it???

SOURCE: Blowing hot air, compressor not kicking on, just fan ? ?

are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.

SOURCE: Amana Cooling Condensing Unit fan won't kick on

be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck

Testimonial: "Yes, it's dual run capacitor problem. I used a stick to spin the fan blades and it starts to slowly spin and up to normal speed, so motor is good."

Do you know what could be the problem?

All the motors including the compressor on the outside unit have start/run capacitors. These can fail and when they do, the motors wont start

My unit blows out cool air for maybe 3mins. Then warm air

Normal ACs (non inverter) work in the following way
  • The AC compressor runs continuously till set temperature is reached in the room
  • The compressor then switches off, but the blower fan in the wall mounter unit keeps running. Durint this time the AC fan blows air out at Room temperature (which feels warmer)
  • When temperature of room rises then compressor starts running again. During theis period the air coming out from the inner uny is cooled by the condenser coils
  • And the process is repeated.... as long as you keep AC running
Ac works this way throught the operation period.
Now if you feel that your AC keeps switching off and on very frequently check the following
  • Your AC may be over powered for room *for example a 1.5 ton AC installed in a scenario where 1 ton is enough)
  • If there is voltage fluctuation in your area then the compressor may keep shutting don on large voltage swings
    • Solution: Get a Stabilizer
  • You have set the temperature setting too high. Max temp suggested for ACs is 25 degree Celsius, any higher will mean the compressor shuts down often. Remember every compressor shutdown and startup draws a high starting current
    • Set AC temperatures between 22 and 24 degrees Celsius
  • The thermostat/ Temperature sensor is faulty
    • Get unit inspected by Authorized technician
  • There is dust buildup on the outer unit / compressor unit. The dust buildup may cause overheating by preventing efficient heat exchange, This may lead to overheating of compressor and it shuts down to, prevent damage to itself
    • Get unit serviced by Authorized technician
  • The fan motor of the outer unit is not working properly
    • Get unit inspected by Authorized technician
Remember to get the AC serviced at least thrice a year to ensure smooth operation

Nordyne E1EB 012HA, outside unit would only come on at times when kicked if it didn't run normally. The Honeywell Programmable thermostat has Cool On I have tried to reset it also but it stays on.

First of all, fan on the tstat (on or auto) is referring to the blower fan not the outdoor fan. For the outdoor fan to run system must be set on cool and the setpoint temp must then be lower than the room temp. So what you are saying is the unit begins to work when you kick it??? Possibly you have a lose wire somewhere, check all connections outside. What type of checks have you performed on the capacitor?

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.

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Clockwise, counterclockwise which is the summer setting?

Ceiling Fan Direction These recommendations depend actually on the height and size of the room; the season; and the activity taking place in the room.

The basic fact of nature is that warm air rises to the top and cold air settles on the bottom. Air settles in layers from warm at the top to cold at the bottom, if left alone at equilibrium.

Ceiling fan recommendations:

In the winter
Set the fan to run counterclockwise (reverse; this looks clockwise as you are looking up). This will redirect the warm air from the ceiling and down the walls and into the living space where the people actually are. In a house, you would run the fan at a low speed so that you don't actually cool the warm air that you are moving downward. If you have a high ceiling, or are trying to heat a hall or a church, you may want to increase the fan speed so that the warm air will reach the living space as long as the fan speed does not create an unwanted downdraft at the people below. In the summer
In a room of normal height (8 - 10 ft), you should operate your fan so that it turns clockwise (this looks counterclockwise as you are looking up), causing a more directed downdraft, especially with the fan running slightly faster. This causes a wind-chill effect because the skin evaporates slight amounts of water from the sweat glands and thereby provides cooling through the skin's surface. However, the air is only moved but not cooled! You may find that you can turn your thermostat down a degree or two and save more money on energy costs. The air blowing down won't actually cool the room though, so you should turn the fan off when there are no people (or animals) in the room. In a high hall or church
It may be best NOT to run the fans at all in summer. This lowers the demand for cooling since the hot layer on top is an excellent insulation between the cool air near the floor (and the people) and the hot roof and outside.

A large, tall manufacturing hall would typically have different goals. There one would have a floor full of heat producing machinery plus the people operating it, working hard and welcoming a bit of a breeze. Then it would make sense to run the fans at fairly high speed to create a certain and directed downdraft. And with the shifts going throughout the days of the week, the fans should be running all the time and maybe in all seasons.

Finally, fans typically use 80-100 watts. When used properly, ceiling fans can really help to optimize the comfort level of the people and save energy and money.

Outside unit come on for ac but inside won't come on for ac or heat

Turn Tsat to fan to see if inside unit will come on. If it does Tstat needs replaced. If not it is fan motor or fan relay. Possible cap. Do you here the fan relay come in. If it is a Good man unit it is time delay and you wont here it. Need to know your make of unit. Rusty

A/C quit running

This question is really to broad to answer. There are several things that could cause it to stop running. I think I would turn everything off, let it cool down for several hours and try it again. When you kick it back on, take note of what is running and what's not running. Inside fan, outside fan, compressor. If the outside unit will not run at all it could be as simple as a grasshopper caught in the contacts. If you hear the compressor running outside but no outside fan, The fan motor probably needs replaced. Please make sure that all power to the unit is TURNED OFF before removing cover plates on outside unit and before trying to remove insects from contact points. Check all wiring inside outside unit while it is open. Also check capacitors for swelling or leaking. If you don't know how to turn all the power off or open the outside unit, you need to call a professional AC technician. Hope this helps. kstfas
