Question about Weather King 10AJA2501AH Air Conditioner

Central Air Compressor Runs Constantly

My Central Air unit will not stop running. The blower inside will kick off when the temperature gets down to the specified limit, which happens fairly quickly. The air coming out is very cold and appears to be working properly, but the Compress will only stop when I flip the breaker.

Sounds like the contactor is stuck in the outside unit. Turn off the breaker or safety switch, remove the cover, and tap on the body of the contactor with a hammer handle or similar tool. If a click is heard you may have dislodged it and it may work for either a short time or indefinitely. (yeah ,I know that's kinda vague) Test it. If that doesn't clear it up, disconnect the thermostat wires just to make sure and re-test. If the compressor starts without the thermostat connected, you will need to replace the contactor. If you feel real handy, you could perhaps remove the cover, seperate the contacts with a screwdriver, dress the contacts with an emery board until smooth and shiny, and try again.

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool


My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

My central air conditioner is making a whistling noise in the inside unit when the compressor is running. It's not the blower because the noise stops after the outdoor unit shuts off. It's also not blowing...


Hello,
If there is no cooling (meaning no cold pipes and not blowing cold air) then check the outdoor A/C for any visible/obvious issues; breakers not tripped, no debris blocking the outside unit from passing air through it, etc. If all looks ok, you can start checking some things inside of the unit if you feel comfortable doing so. Also, most indoor heaters have a higher speed/rpm for the fan when the cooling kicks on, and the heat runs on a lower speed/rpm.

Hope this helps James

My outside fan will not run and the inside unit runs constantly. can't push the reset button on unit outside


Your out door unit fan motor not runs due to pressure not build up at Heat mode. If its cool mode only fan runs with compressor when thermostat calls for it.

Without having technical knowledge, don't press any reset button. Hope it's helpful?

Goodman central air conditioner not blowing normally


It sounds like the compressor is not coming on in the outside unit. If it worked fine and was cooling before, then your compressor probably over-heated and tripped the internal overload switch which causes it to stay off while everything else is working. The most common cause of your compressor over heating is an incorrect refrigerant charge, though it could be a few other things like a restriction in the copper line set. You will be able to hear the fan motor and the compressor kick on if you listen close while the system first turns on. If the compressor is over-heated, then after it cools to a save temperature, it will come on again, but only till it over-heats again. I would have the charge checked on the system, but remember that if the compressor is over-heated when the technician gets there, there is nothing he can do until it cools down and time is money! It's best to not run it until the problem gets figured out. Hope this helps and points you in the right direction. Good luck!

Why does my fan runs continus. and the condenser won't run out side.


The fan runs continously because your condensor is not kicking on and removing the heat. The thermostat needs to come under the set temp. to kick off the fan. If your compressor doesn't run and the fan on the outside unit does run, your compressor has an issue. If nothing runs outside, then your transformer on the inside unit(air handler) has an issue. This could also be a control relay on the condenser or the air handler.

I have an old RUUD central AC unit that started blowing hot air. I set the thermostat to off and set the temp gage higher than air temp to turn the unit off and save money, but inside blower unit runs...


Hello

Okay did you check your thermostat to see if you have the fan switch on auto? The switch must be on auto or the fan will continue to run. If the thermostat fan switch is on auto then there is a malfunction in the thermostat probably. You can go to your forced air unit and on unplug the unit. That way it will not turn on at all, because the forced air unit is controlled by the thermostat. Hope this helps.

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.

Ruud 12 seer heat pump not heating


It sounds like the unit is tripping off from high pressure. Check you filter and indoor coil. You may have low air flow inside that is causing the refrigerant pressure to be to high.

Carrier central ac model 38EN036300


If you have an electronic thermostat, they can short out, leaving the compressor running. Also, the big relay that runs the compressor can get its contacts welded together. See if the contacts are stuck closed.
