Yes it is the blower motor,

it is stopping due to mechanical problem.
it may need a simple re-oiling of the bushings or bearing replacement or conversion from bushings to bearings.

tnx 4 using fixya.

Yes the blower motor is trying to go out. you can probably take it out of the casing and spin it with your hand to get it going again but it will only last a few min. i would suggest to by a new a/c

What causes my AC to sometimes stop cooling & can hear a buzzing from the motor?


The blower motor probably needs very badly to be cleaned, lubricated, or replaced, Michael.

more than likely could be the capacitor or a bad condenser fan motor. Can you hear the compressor running? If you can then its the cap if not check to see if you have voltage to the contactor. Does the fan hum if it does give the blade a spin with a screw driver if it runs its the cap you can feel of the motor if its hot you need to change it/

Rheem classic 80 fan motor on furnace hums will not turn on


Have you checked the capacitor? Try spinning the blower wheel by hand, if this gets the motor going you have a bad capacitor. If not, the motor will need to be replaced.

Blower fan does not operate


I assume you are referring to the indoor blower motor. can you here a "hum" from the blower motor as if it is trying to come on and sounds "stuck"? If so, while its humming safely give it a spin (WATCH YOUR HANDS BLOWER WHEEL IS SHARP) . If it takes off and runs you need a capacitor

Hi' I have a coleman roof top AC unit on a 1991 Tioga i just purchused a couple of months ago! When i turn on the AC it makes a humming sound...no fans spin or no air comes out! If i let it hum for...


Hi,
The blower motor is seized up...you will need to get up top and remove the cover...then remove the fan blades and the motor and replace the motor....sometimes a temp. fix will be to get WD-40 and then oil worked into the bearings...but that is usually a very short lived fix...
Replacing the motor can be frustrating and time consuming, so you may want to hire someone to do it for you...you may also find that a replacement unit is more cost effective..

I replaced the fuses with the proper ones thinking that that was why fan on ac unit was not on. I did the 24 hour off on electrical panel, and replaced fuses, now i hear a click then a humming sound coming...


The humm you hear is the compressor. Turn your unit on and let it run for a couple minutes and grab the large pipe at the outdoor unit. If it's cold, your compressor is running. If your fan didn't turn on, there is a good chance your motor is fried. It could be your contactor, but I doubt it. The compressor and fan are wired through the same contactor, so when one comes on, so does the other. DO NOT run your unit for more than a minute or two with the outdoor fan not running. If you continue to run it, it's going to go out on high pressure and turn back on, and so on, and so on, until it fries the compressor.

Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from...


Hi!!

This means that the condenser fan motor (outside unit) failed, this caused to build hi pressure and either activated a safety valve to release the extra pressure or blew a line and R22 Refrigerant escaped from system.

The fix is to replace motor fan and capacitor find the leak and refill system with R22 Refrigerant Gas. It is safe to turn on the Fan Only mode on the Thermostat until a HVAC Tech arrives.
To perform this job parts and labor included will cost: about $300 -.$400. Look on the Yellow Pages for a Tech in your neighborhood.

Samsung Ac compressor stops after 20 minutes and fan keep running. Again after 10-15 minutes if ac is restarted the cooling happens for 20 minutes and compressor stops.


eventually,cycling process is doing done if the thermostat sense the configure temperayure set up it will trigger to stop your compressor motor as well as the blower fan,blower fan independenly to you compressor.if your thingking that your compressor is tripping off,check your operating current on one line using clamp ammeter and compare to the rated current that tag on
motor compressor body,if the current flow is higher than the rated current specified on compressor motor,well problem occured it will trip your compressor,because overload protector is becoming your thermostat.but if you got same current result it was cycling process.If tripping off maybe air is present in your system call qualified ac tech, to purge out air in system.

Furnace Blower stops working after 15 minutes


Replace the blower motor. Cleaning of the blower and motor will help in the moving of more air but will NOT eliminate the real problem in the motor bearings. Over time the lubrication will dry out and bearing wear results.
