Possibly two or more problems. drain may be plugged and therefore no water dripping from it. attach a good wet dry shop vac and **** it out. listen for good suction at in door coil when vac is attached outside . feel large insulated line outside . it should be ice cold to touch but not frozen . if it is kinda cool then your low on gas. if its froze you are low on gas or dirty filter ,coil , or blower wheel. .you can measure temp drop between return air in and supply air out at the in door blower . it is usually 18 to 20 dgrees , in at 80, out at 60 so to speak. greater than 2o and you have a restriction like dirty or filter or froze up. less than 15 you are low on gas or inefficient compressor. be sure your fan is in the auto mode , not the on mode or indoor fan will run 24-7.

Rheem Heat Pump outside fan seems to be running 24 hours per day. Outside temp 23 degrees. Is this normal? Model #RPKA-018JAZ


no this is not normal. the fan should stop running when the thermostat is satisfied or when the heat pump goes into defrost mode. if it is running nonstop, there is a contactor that operates the fan and compressor that if it sticks will get line voltage to it. you would have to take the cover off of the outside unit and turn the thermostat to off. If the fan continues to run, you need a new contactor.

No A/C.


It maybe the blower motor. Determine if the blower motor is getting ac, if not getting ac to the blower motor then there might be a breaker, which would probably be located somewere near the motor, or the motor has an internal breaker or fuse.

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

Central air conditioner won't stay running


Sounds like it cycles on either head pressure or low pressure. If you have a Carrier unit it has both controls. Is your outside fan running. Is your condensor dirty. A unit that old needs to checked bby a service tech. Remember freon does just go away. If he puts gas in your unit there is leak. HINT Ask for free estimate on repair before it is fixed. That way you know the cost up front. Rus

AC WILL NOT SHUT OFF


SOUNDS LIKE THE T-STAT TEMPERATURE SENSING BULB IS OUT OF "AIR-FLOW" (SOME CAN COME LOOSE FROM THEIR MOUNTING CLIPS) OR IT IS BAD ALL TOGETHER ... MOST MANUFACTURERS HAVE A ONE-YEAR WARRANTY ON SMALL PARTS AND 5 YEARS ON THE COMPRESSOR .., HOPE IT HELPED.
