Blower fan keeps shutting on/off,

I have a central air unit (goodman, 4years old) the blower fan keeps shutting off and on, however the condensor unit outside stays on? Could it be the thermostat, if so why is the outside unit still running? Or bad blower fan? or something sending the signal to shut on and off? The house is cooling, the outside pipe is cold too? Please any help???!!!
Thank you

    having the same problem, but when I put the fan in the on switch, it is still turning on & off.

    My air conditioning unit runs, however, the fan in the furnace is not blowing the air through the ducts. It doesn't seem to be running when I test it by turning the heat on either. Advice?



    I have never conducted any preventative maintenance on my air conditioner. Oops.

Try putting your fan in the on not auto position and see if your outdoor condensing unit cycles on and off. If it does you might have a defective time delay relay to blower. If not your contactor might be stuck or your thermostat could be defective.

Your blower fan turning on and off shows your thermostat is working. I am willing to bet you have the fan in the automatic condition. Check for a sticking contactor at the outside unit.

I have a goodman ar24-1 blower motor that will not start. I have changed the capacitor, checked the thermostat, spun the blower motor but still will not start. Outside unit runs but no blower. Any ideas?...


Check the relay or sequencer that controls the blower if it has one of those. If the fan is controlled by a circuit board then you problem may be there. If it is controlled by a circuit board then you can check for power at the fan connection when the fan is supposed to be on. Then there is always the possibility that you blower motor is burned out. You can use and ohmmeter to check the motor windings. You said you checked the thermostat, how did you do that? If you install a jumper between the R and G connections the fan should run if everything else is OK.

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

71122 ac model starts but the fan does not blow any air .shuts off within seconds.


which fan shuts down? Outside condensor fan? Or blower inside? If its the outside condensor fan motor you probably have a bad run capacitor or a bad condensor fan motor

Central air conditioner won't stay running


Sounds like it cycles on either head pressure or low pressure. If you have a Carrier unit it has both controls. Is your outside fan running. Is your condensor dirty. A unit that old needs to checked bby a service tech. Remember freon does just go away. If he puts gas in your unit there is leak. HINT Ask for free estimate on repair before it is fixed. That way you know the cost up front. Rus

Bryant central air unit fan doesn't stop.


This is a condenser fan and as long as the A/c unit is in cool mode, this fan will run. The only time it should shut off is when temperature setting is satified and the unit shuts off.

Goodman split unit that heats instead of cools


Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution. Thanks, kstfas
