Question about Heating & Cooling

1 Answer

Central air seems to be working fine except for the outside unit fan stays on all the time. The line to the outside compressor also drips condensation from the furnace all along the basement to the outside wall.

    Yes the line has insulation, and yes the outside coil is clean

  • r54ick May 10, 2009

    Yes , the outside unit never shuts off.

  • r54ick May 10, 2009

    Yes the inside unit shuts off when the proper temperature is reached.

  • r54ick May 10, 2009

    When I turn off the air at the thermostat,the outside fan stays on. To get it to shut off I have to shut off the main a/c power at the box.

    Where exactly would the contactor be located??

    The contactor is in the electrical control box located inside the outdoor unit. Becareful as this has 220V. a safer test would be to remove the thermostat and expose the wiring, then remove the wire going to the (Y) terminal and see if the unit stops.

    You may have a thermostat problem. Does the inside unit shut off when temperature is reached ?

    How is the inside coil ?

  • Robert Moller
    Robert Moller May 11, 2010

    That line should have a rubber tex insulation around it. Also is the coil clean ?

Why won't outside fan turn off

the contactor is probably stuck shut you can check to see if it is its the big black thing that has all your power coming in and going out to unit to run fan and compressor. If it doesn't shut off and your inside unit does then it will freeze the lines and coil and water will drip when it starts to thaw out.

Central air conditoner outside unit

Well, the answer is yes. I have seen a bad capacitor cause a fan motor to run backwards. BUT..... After replacing the capacitor and WIRING it up the right way, everything should be fine. A lot of aftermarket condenser fan motors are reversible, so it can run counter-clockwise (CCW) or clock-wise (CW). However, most factory fan motors come one directional and on your specific unit, the air should always push out of the top. Running the unit with the fan going backwards will actually some-what do it's job, but damage other components like the compressor because it runs at higher operating pressures than what it is designed for.

Have someone else look at it! That's going to be the best advice I can give you. If they can prove that a capacitor caused the motor to permanently run backwards..... I want to know! Hope this helps and good luck with your unit.

Water dripping from unit need to access drip tray and drain pipe on indoor unit

It sounds like you have a central a/c that has part of the system, the compressor, condenser coil and fan outside on the ground, and the rest inside. The inside part, the evap coil, normally uses the same circulating fan as the heater. If this is the case, then locate your heater access and you should find the evap coil and its drip pan in the duct work.

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!

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

My a/c system is blowing hot air; outside fan is not engaging

First check for line voltage 240v...if thats good .check for burnt wiring at fan capacitor.if you hear the compressor humming but still no fan you may need a fan motor.. when buying your new motor make sure to match horsepower and r.p.m

My colmen central air unit is not working properly. The Outside unit is not working. The problem initally arouse in June, but it "self corrected" after having the A/C unit turned off. Since that...

If nothing is running outside at times you probably have a weak contactor coil that is not pulling the contactor in all the time. If the outside fan comes on but not the compressor, the compressor is over heating and shutting off on overload protection. This could be a dirty condenser coil, low on refrigerant, the compressor it's self. The compressor comes with a 5 yr. warranty.
