AIR CONDITIONER NOT COOLING

The fan on the inside is on and blowing but the one on the outside isn't. There is no leak and the breakers is fine. I changed the filter on the inside of the house yesterday morning. and i also cut the unit off since 5pm yesterday just in case it is frozen on the outside. Could this be the problem that its not cooling. I was going to try to cut it on again today when I get off work to see if it will cool

Ok, there should also be a service disconnect near the condensing unit usually a 6'x8-10" or so grey box, you need to check this and make insure that your 220v line voltage is getting thru. Sometimes this disconnect is a breaker sometimes fuses and sometimes just a bar type plug ( if the disconnect is tripped the problem is likely a clogged condenser coil, proper cleaning will be needed to prevent it from tripping again) If this is not tripped and you are getting 220v to your condenser then you need to confirm that you are getting the 24v control voltage to the compressor relay from the transformer in the indoor section. If the indoor fan can be controlled at the thermostat it proves that your transformer is good and you have 24v available, you should be able to hear and see (if your looking at it) the compressor relay engage when the thermostat is set to call for cool and the compressor delay on circuit has expired (usually 5 min). If the relay is not engaging then look for a wiring problem between the condenser and the furnace. Do you have dogs that run near the condenser? I often find Improperly secured t-stat wires getting pulled loose or chewed up by the family pet. You should have found the explanation for the fault at this point GL!

Ac outside..copper tubes freeze up,not cooling well inside


No! Check the condenser isn't clogged up first. Then check all internal filters and fans. Check for leaks with an electronic detector and repair any leaks before vacuuming the system and maybe then replacing the refrigerant.

The outside unit has power going to it but isn't


maybe it has tripped off on high pressure, as you have have said the fan is not turning so will cause high pressure. now assuming the problem is the fan is not running than check the condition of the condensator /capacitor for the fan motor. if the motors winding is still good replace the capacitor and try it ON.

Rudd air conditioner isn't cooling,blowing ,but isn't cooling my house because air is not cold


Hello, first check if the outside unit is running, if it is then check filter to make sure it is clean and that the blower wheel is clean and not dirty. If the unit is clean then most likely you have a low refrigerant charge due to a leak and will need a hvac tech to come out and fix the leak.

Air conditioner comes on but is not cooling the house....new house, new unit


Try going outside and locate your outdoor unit. If the thermostat is on, and the fan is running inside, the outdoor unit should be on as well. If it isn't, locate the circuit breakers in your breaker box. There will be two. Trip them back and all the way forward.

If the unit is running outside, sometimes the air cond contractor forgets to come back and charge the unit with refrigerant. In this case be sure to contact the air cond contractor that installed the unit.

The air conditioner was working today i have a RUUD UAKA018JAZ, the fan is running however it is not blowing cold air out the vents


Hi, your problem is in the unit outside. Check to see if the fan is on, make sure the compressor is running also. If nothing is on, check the breaker to see if it tripped. Also, the box at the unit has 2- fuses inside behind the plastic cover you can't see unless you remove it. If the unit is off and the breaker was ok, remove the cover and replace BOTH fuses. Do all of this and let me know. If the breaker keeps tripping or blowing fuses if the unit was off, you have a componant shorted. It may be off or on and not cooling well due to a loss of freon. If it is on, hold your hand above the fan to feel the air. It should be nice and warm almost hot if its hot outside. Let me know what you find please. We can find the problem.
Sincerely,
Shastalaker7

Outside makes loud noise


I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

AC breaker trips after 10 minutes


Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.(koolbreezes74401@yahoo.com)

Not Cooling


Yes, the compressor might not be running. Possibly a bad run capacitor or maybe burnt wires on the contactor or compressor flags.
