The problem could be the capacitor for the fan motor or the fan motor itself. Turn off the power and use a long screwdriver to see if the fan will turn freely. If it doesn't it needs to be replaced. If it spins freely then check the capacitor. You can do that with a multimeter with the capacitor check function or take it to a heating and air supply and they can check it for you. If the capacitor looks swollen then it is bad. Some units use a three terminal capacitor that is connected to the fan and compressor. Make sure you check the fan side but it wouldn't hurt to check both while you're at it. If the capacitor is good then use an ohmmeter to make sure the fan motor windings a not open or shorted. The increasing noise probably comes from the head pressure building on the compressor because the fan isn't running.

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Auto/On set to ON. Fan runs.


Sounds like the thermostat, the way to verify is to unplug indoor unit, remove thermostat, take pic of wiring with phone or label the wires as to the terminals. Carefully twist the yellow,(Y) Red (R) and the green (G) together. Plug the furnace back in, if the unit operates normally, replace the thermostat. I am basing this on the fact that the blower speed is changing. This could also be an anomaly within the circuit board in the furnace section, not likely though as the outside unit (condenser) is not controlled n by the indoor board unless this is a heat pump. hope this helps.

I have a goodman gsc13 ac unit about 4 year old. When the temp gets around 90 or above outside the fan on the unit starts but the compressor does not. I had service check it out but that day they were...


It sounds like the unit may be over charged. Make sure the outside coils are clean and you have plenty of airflow coming out of the top of the outside unit. What could be happening is, when the temps get higher outside, so do the pressures in the system. The compressor has a thermal overload protection that will kick the compressor off if it gets to hot, which if the compressor is over charged, it will work twice as hard, over heat and shut off. You would need a technician to come out and get the refrigerant charge back to normal. Another thing that could be happening is a weak or faulty capacitor, which is a small round or oval metal object, found in the electrical compartment on the unit. This are fairly simple to change out if your comfortable with electric. I've also had to put what's called a hard start kit on compressors with the same problem, new and old. The hard start basically gives it that extra boost of power to get it up and going. I would start with the refrigerant charge and go from there. The electrical "humming" sound that you hear unless you turn the breaker to the furnace off, is the contactor on the outside unit having a call for cooling. The 24 volts come from the furnace, to the outside unit, and pulls the contactor in to power the unit with the 220 volts supplied. It is normal and you don't have to worry about that at all. I hope some of this helps and good luck!

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.


The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Goodman package- no heat below 30 degrees outside


I believe the unit you are describing is a heat pump. Heat pump are great when the temperature isn't below 30 With low ambient temps. outside it is much more efficient and comfortable to run aux. electric heat from the heat pump.

Fan running constantly in the house


Check t-stat and make sure fan is set to "Auto", that might be why fan is running all the time, or it could be a fan relay that is stuck closed. It sounds like you A/C is over charged or you have a bad high pressure switch, this was a common problem with this manufacture especially in the heat mode.

Goodman Model CK60-1C with White Rogers mercury tube thermostat


The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.

I have a carrier infinity system. On the thermostat it reads "sens error" where the outdoor temp is normally displayed. The inside unit is running but the outside unit is not. Any suggestions?


A burned or pitted contactor will/can cause a unit to not run. Outside fan. Just thinking out loud. Start with low voltage check at t.stat then check outside low volt. Set t.stat to on. If fan engages at least your transformer is good. Next set calling for cool. Drop t.stat 68-70. If nothing happens go outside and with a screwdriver depress the contactor in. If fan and compressor kicks in change the contactor. If contactor is pulled in check outside fan. Remove the wires from the compressor and see if the fan will run . If it does you have eliminated start components as good. The compressor has to be check. It needs to be ohmed out. Turn off power at disconnect. Pull the cover on the compressor. Check between pins; then pins to ground. Open or infinite is good.Have you checked fuses. Like small 3-5 amp fuses
