A/C runs but Compressor Does not Kick-In

A/C was working fine earlier in the day but now when the thermostat calls for the A/C the unit makes a low hum or groan but never kicks-in.

    There is pbobably a small, blade type fuse inside the unit on the control board. It safeguards the control board. If it's blown, look for other damage before you replace it. Use only the identical size fuse.

Sounds to me like the contacts that are humming. Check your fuses or breaker.

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 own a coleman EB15B cental heat and air unit, it stopped working two days ago, I replaced the fan and a new motor but the unit still will not blow cold or hot air when I set the temperature. The unit has...


You need to make sure the compressor is running. If the compressor is NOT running , the fan will turn but there will be no cold air. If the compressor is not running, check all the wiring to make sure a wire is not burnt off. Pull the fuses before inspecting.
If the compressor IS running, you may be low on refrigerant. If you have a set of guages to check the pressure you can find out if it is low on refrigerant or not. If it is an older refig 22 system the low pressure side will read about 65 lbs on a 80 degree day. If you have no experience in this, you may need to call a service tech to check it for you.

Hello

Sounds like the compressor is shuting down on high heat.There could be a couple reasons for this.
1 Check that proper voltage is being supplied to compressor.
2 Freon level may be low.This would be a service call.
3 Bad or intermitent connection at thermostat.
4 Main contacts to compressor sticking,usually burnt or pitted.

Heatpump r-22 rudd system,unit runs starts out heating then compressor stops in middle of heating ,this unit has a out side air temp. sensor just wondering if possible bad board or not


If compressor stops in middle, check the following.
1.Thermostat setting must be minimum +3 degree than your room temp
2. Check it's in heat "mode"
3. Check indoor and outdoor coils are clean.
4. Check fan motor is working alright.
5. Outside sensor and room air sensor is placed correctly.
6. Gas pressure is o.k
7.Check compressor is overheated, even all the above is o.k.

Unit shuts off on hot days


It may be low on refrigerant. On hotter days, the compressor has to run longer to reach the temperature you have on your thermostat. Have it checked for the proper refrigerant charge and have them test how many amps that the compressor is pulluig as well. With the proper breaker installed, the unit should not be tripping out. Make sure that the breaker that is in there now is actually the proper one for your unit.

My compressor on my coleman tsr will not kick on I can turn the thermostat all the way down and then ease it up the compressor never will come on it worked fine the day before


Check that the thermostat is OK. You can do this with an Ohmmeter or a Volt Meter. If it is cool only, there are two terminals on the rear. Cut power to the AC and remove these wires and with an ohmmeter, check the two terminals for continuity. If there is none, then turn the dial all the way to the coldest setting and see if it changes. If not, you have a bad thermostat. If you have continuity and the compressor still does not come on, check the Start Capacitor in the upstairs unit.

New Goodman condenser unit run almost contiously using too much e


I'm not sure of the kilowatts. The 10 min on and 5 off is telling me there is to much heat by the thermostat or you house needs more insulation. The new compressor is designed for more efficient run time. The other thing is the unit to big for your house? It should run 10 -15 min when low humidity is in the house. Otherwise longer if its pretty warm inside.

Will not cool properly.


You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

I have a coleman/evcon heat pump. When the thermostat kicks on the contacts kick in and hum but the compressor nor the fan run. Is this probably my capacitor has gone bad?


I would check the hig voltage power supply to the unit. Check the main breaker and make sure it is on. Check the disconnect and make sure there is power at that point to the condensing unit. The contactor will kick in from the low voltage in the control circuit.
