Hi! there,
well we have to do something about that,if you mention of fan spin and it pushes air but no cold enough on it,this refer to blower on compressor, there is fan on outside the condenser,so we are on blower w/c does not blow enough cold air,there are factors we can check,first thermostat try to adjust thermostat to the coldest point,
observed if cold was increasing if not, 2nd have clean the filter from evaporator it may have a clogged, check evaporator if there freezing ice on bottom portion of evaporator w/c cold was coming out,have it clean,cleaning this is done by certified a/c technician,there is problem if have an insufficient cold,this is the symptom of your system was under charge lack of freon,this can check by technician w/ clamp ammeter device.the operating current should be equal to rated current on manual,inform service center about this,have a nice day don't forget to rate me.thanks's

You say the fan spins and it is pushing air, but not cold enough. Which fan is spinning, the one in the attic? If the fan is not spinning in the compressor unit outside, that is why the air is not cold....the compressor is not running. I had that problem recently and the problem was bugs. They got into the relay in the compressor unit, where one got between the relay contact points so that the points failed to make a connection. If your compressor is not running and you are competent to check the relay, take off the cover to that part of the unit and use a non-conductive probe, like a wooden rod, and push on the contact points. The air conditioner unit in the attic has to be running for this to work, if the relay is the problem. I was lucky, and that was it. After a couple of months the bugs returned, so this time I sprinkled some powered insecticide inside the relay compartment. Weird, huh? There will be a switch box beside the compressor unit so that you can turn off the power if you need to. It affects the compressor only, so the attic fan will continue running. It has to be on to do the procedure I described. If your attic unit fan is working, but not the compressor, you could try hitting the compressor box with a rubber hammer. Sometimes that jars bad relay points so that they make contact. You will be very lucky if any of this works, but for me it saved the expense and delay of a service call.

I have a Rheem 10 SEER/4 ton AC unit that just had the compressor replaced. As soon as that was fixed my Rheem water heater began to run hot, another words the temperature pressure release valve keeps releasing hot water every 24-48 hours out the drain pipe, the water heater thermostats were cahnged but a day later their is hot water still coming out the TPR drain pipe? Is the AC pushing too much hot air into the water heater and what is the fix? If the plumber changes out the TPR valve I'm afraid it will continue to release hot water if there is a hot water pressure buildup, what is causing this, the plumber says it is not connected to the new AC compressor??

Rheem air conditioner fan not working outside


with the unit off: use a stick or something safe to try to move the fan blades to be sure the motor is not seized. If it spins freely :turn the unit on and use stick to give the fan motor a "boost". if it takes off and runs you have a bad fan capacitor which is the most common cause of your problem

Rheem RAKA 037 JAZ


When power is applied to the motor try spinning the fan blade with a small object such as a stick, if this gets the motor going than the capacitor is faulty and must be replaced. The capacitor is located in the outdoor unit.

You need to replace the fan capacitor. Your compressor is probably in thermal overload you can cure this by turning off the disconnect your ac voltage and taking a cool water hose and running over the top of the compressor for a while. Then turn your disconnect back on and listen and feel of the big copper line to see if it gets cold and also listen to see if the compressor kicks on.

Compressor comes on, some cold air, no fan?


Try spinning fan by hand. If it spins freely, change capacitor. If fan is tight, change fan motor.

Just replaced inside fan motor on 5 ton Rheem heat pump. Fan will not spin freely. What to do?


1) remove power from the unit
2) remove panels enough to see where the squirrel cage fan is binding
3) these units are normally adjustable by loosening the bracket which holds the fan motor and simply moving it one way or another just a bit. (which is why understanding which end of the fan is binding is a GREAT second step, right after step 1, remove power from the unit, that includes shutting the emergency heat coils breakers OFF.
Don't worry, you're close to the solution!
