SOURCE: Rheem Classic X Humming

does the indoor fan come on if fan comes on then the problem is out side if the fan is not coming on and the breaker blows this will turn off the out door unit also due to the 24v transformer is located in the indoor unit your system has two breakers one for out door and one for indoor units as far as your contactor goes with power off look at the contacts if pitted bad replace it most need replaced after 5yrs also check for voltage drop on the load side look at the capacitor to make sure it is not swelled up on top if so then bad unplug the fan motor and bump the contactor with an insulated object to make sure the compressor is running if not with power off remove the cap on the side of the compressor and look to see if wires are connected good they some times get lose and ends burn off also on the contactor they some times buzz when bad hope this helps with your problem

SOURCE: Can a Carrier 38CKB030300 be replaced with a Trane

the tons is the power of the unit, so sure. if you were happy with the power of your old unit, get the same. if you felt it was never strong enough to cool your house, get the next size up. newer units have the same power, but use less energy.

SOURCE: blowing hot air fan not turning outside making a humming noise

Replace the run capacitor. It is a silver cylindrical object located in the electical compartment of you outside unit. There is most likely three places on the top where different color wires are attached. One is marked F,or Fan. The center should be marked C, or Common, and the last should be marked Herm, with wiring to the compressor. Make sure you write down or label each wire you remove and it's correct location. They must be installed on the new part just like they were on the defective part. For you to know which dual run capacitor you need, the old one will have printed on the side either 370, or 440 v,as in volts. You must also need to know the microfarad rating and it is also printed on the side with the voltage rating. Since this is most likely a dual(runs fan and compressor) you should see two ratings abbreviated as mfd. Something like a 5mfd for the fan motor and perhaps a 35 mfd for the compressor. CAUTION !!! This device has line voltage and you must insure the power is off at the disconnect/ breaker BEFORE you begin the repair. Sounds complicated but really only takes a few minutes. The main thing is getting the right mfd and voltage ratings for the new part and keeping a record of where the wires were mounted on the old one, and putting them back the same place on the new part.

Brown and grrey brown strip go to seperate capacitor. but you can tale off the gray/brown and use it by putting it on the capacitor where the other wire come off. Russ

How do i stop my ac from make a loud humming noise when it is time to cold


It depends on what is humming. If it's on the outdoor unit it may be the CONTACTOR. If its on the inside unit, it may be a relay or the tranformer. Can't give a good answer unless we know what is humming. On the o.d. unit is the contactor and its usually what hums only when its cooling. In the electrical panel it is the component that the main voltage wires connect power to the unit. You can change that part and it should go away BUT! I would suggest calling a service tech. Or wait until you need service and have it changed then. A miswire at the contactor can damage the compressor. Work safe!

a contacter can be bad even if it is open, power still could pass through it bacause it is stuck down, breakers are the same way thay could be in off position but power pass through them always check with meter first, this happens because of heat that fuses the switch together . , parts go bad for many reason fatigue is just one of many.

Its possible that the contactor that closes to start the outdoor unit is not pulling in and passing power. You are hearing the coil humming since it is getting control power. Also first check that breaker for outdoor unit is not tripped

Upgrade Baystat 239 to a Honeywell RTH7600D controller


For Trane sytems, B is your "Common" wire. O is your reversing valve relay, G is your fan, Y is your compressor contactor, R is Hot, Brown will not be used on your electronic tstat. X2 is your backup electric heaters. Without knowing what terminals are on your new tstat, I cannot offer more information than this. The installation manual may indicate what each terminal is controlling. I strongly suggest to write down ALL of the terminals and colors from your old t-stat and be sure to turn off the power to your air handler. Put the fan switch on your tstat to ON before turning off the power. Make sure the fan is running. Then turn the power off to your Air Handler. If your fan stops running, you have turned the power off to your tstat and are ready to start replacing it with your new tstat. I hope you find this helpful. Good Luck!!!

Not blowing cold air. Checked outside unit and looks clean but fan not turning


You may have a bad capacitor, fan relay/contactor, or motor. Check the capacitor for the fan, if the capacitor is ok, then check the fan relay/contactor. If this is ok, then the fan motor is bad.

You need to check if you have full 220 voltage to unit sounds like one leg of your power is out. You have slow blow fuses on this so turn off the breaker that goes to unit and then pull fuses out and check each one. You can check at the place where the main power comes into unit if you don't mind checking electricity but take your volt ohm meter and check the two power leads on the contactor that is the first thing that the power is connected to. Let me know if that checks out Okay. ken
