Could be a bad fan control board or the motor. Need to see if you have power to the motor from the board

SOURCE: GE Central A/C Unit about 30 yrs old; condenser fan stops after a short time.

I gather that it is the outdoor fan motor that runs a bit then stops.

Fan motors that stop by themselves are overheating and going into self-protect. The fact that you replaced the motor and capacitor opens up a whole world of "which wire is in the wrong place". I could do this if I could see it, but I can't see it. You're probably going to wind up calling a service man to sort out the wiring.

SOURCE: Carrier Synergy 2000 Condenser fan does not turn on

the mfd is stamped on the side of the capacitor.Be careful to kill the power and to NOT touch the terminals.The capacitor is capable of holding a charge even after power is disconnected.

The control board seems to be detecting reverse polarity, and my first thought is that the relay contactors are oxidized, but you could also have a bad startup capacitor, and/or control board.
The only reason I say control board is because the LEDs are blinking- never a good sign, but sometimes unplugging and reconnecting the power resets the board.
The following web page lists the steps to check for this problem, and is a good troubleshooting guide, and hopefully will help you solve this:

Good luck, and hope this helps.

I have a carrier Day & Night a/c - heater unit. the model # 591ANX0480000ACAA, 208/230 volts. my blower fan stays on continuously, even after turning the thermostat off. the condenser fan does not come on...


If the blower fan in the furnace won't turn off, there is a tripped/blown limit. It's a safety. As for your condenser fan it could be a run cap or motor. Do yourself a favor and have a licensed HVAC contractor take a look. Find a NATE certified or ACCA member. You will find a much better more qualified contractor.

Our house is hot! The ac unit outside comes on and freezes up, and the blower is not coming on. We have had the inside thermostat changed and freon added and now a new capasitor but no luck.....HLEp


Man, it sounds like you have a heat pump with a bad defrost board or reversing valve. I assume your description of the unit outside freezing up is the condenser and the blower you refer to is the condenser fan motor. Or, is it the big copper line to the compressor that is freezing up? If so, have someone stand by the inside blower and listen for a click as you move the thermostat fan switch from auto to on a couple of times., Make sure at the time you are testing that the thermostat is in the off position. Those 2 switches operate separately. If you hear those clicks during the test you probably have a bad blower motor if there are are no clicks you may have a bad blower relay or board. Hope this helps good luck.

Condenser fan replaced one year ago, fan not turning but can hear motor


the answer to your problem is most likely the motor start capacitor. A AC motor can run in both directions. The start capacitor is used to cause the current to lag behined the voltage which determines the direction the motor will turn. Its posible the start and run capacitors are in one can. so changing one will change the other. However look for a wiring diagram. Do not asume that both capacitors are wired in properly. They may be fighting one another causeing premature failure.

I have an old Intertherm gas-fired furnace, Model MGH-055AB which ceased operating last night. It was quite warm when I arrived home, and when I set the heat up a little, began to hum, but the fan would...


Tom P's answer is generally correct: The motor start capacitor is usually not the problem. However, in some cases, particularly on older furnaces, where there were capacitors of certain make and production run will prematurely fail. This happened in March on a mobile home HVAC unit where both the blower fan and condenser fan motor capacitors failed open circuit. Both caps were of the same Mfg, and production lot.
Here is a suggestion (for you or an electrically inclined friend): Locate a substitute motor capacitor having similar Mfd (or MF) and Voltage ratings. Remove power from the unit. Reach into the blower squirrel cage and spin it to verify that the shaft is not frozen. Pull the wires from the existing capacitor noting color and location. Connect the wires to the substitute capacitor and secure it place. Apply power and turn on the blower. A no start? Motor replacement time.

I don't know what part of the country you are in, but here in Okla. a condenser motor can be bought by the home owner for around $100. You should be able to go to any appliance supply house and purchase your own motor. Take the model and serial number with you, it may help. If you have a local carrier distributor, they should give you a users manual. Try your best to get a motor close the the same as what you have. Note the horsepower, rpm, voltage and take the fan blade with you in case you need a new one. Hope this helps. Mark

Hi!!

Replace motor fan and capacitor, it is a very simple task. Turn breaker OFF. Then all you have to do is remove about four screws from the top grill, about four more that fasten the motor fan assembly, unplugg electrical connectors and label them and install the new one and switch fan blades.

No special knowledge is required to perform this job. Cost: about $140 +-.

On the other hand, you call a HVAC technician, they supply the motor and capacitor, otherwise they won't give you warranty. Cost $300+. Look on the Yellow Pages for one in your neighborhood.

Good Luck!! Rate this post!!

HVAC Blower Motor Replacement


Ain't nothing to it. Slide out the blower and take it outside. Use some rust buster to get the blower out. Don't beat on the shaft. Spread that shaft and the wheel won't come off. Use a rubber mallet. Most generic blowers have white as a common wire and the speeds are black-hi blue med and red, for low. 2 brown wires will go to the capacitor. other wires will reverse direction. Wash the housing and blower wheel good. any wire unused will be taped off to themselves. Nothing to it.

Evap. fan motor stays on


Sounds like the control board is bad. Does the fan try to run when the tstat is off. Did you check the tstat. What kind of voltage are you getting at the fan motor. Did you check the capacitor. If you are getting voltage to the motor with no call for fan then the control board is bad. Let me know if you need any more.
