Run capacitor had a burnt off terminal. replaced with same capacitor and the same thing happened. wondering what to test to keep this from happening. it is running off a dedicated 230 volt outlet


All electrical comnections must be clean and tight.
It seems that the capacitor terminal was loose amd/or dirty. With a loose or dirty connection there is resistance and resistance consumes power, power dissipated as heat.
Replace the capacitor wire leads connectors with vlean tight ones.
To check for other possible problems, if possible, read the capacitor voltage while the motor is running, should not exceed the cap rated voltage

Is a 45/5uf run capacitor the same as 5/45uf


Yes, the terminals are still marked the same and your compressor (COMP) will always have the larger microfarad rating. What can change though is the voltage rating. It will either be a 370v or 440v. You can use a 440v on a system that originally had the 370v, but not visa versa. Basically, you can go up, but you cant go down. Hope this helps!

On a bryant air conditioner I am trying to hook up the capacitor (60uf/5uf/440vac) that is a replacement.I have two yellow wires,one brown wire and one blue wire.Which goes to herv,fan and c


On the top of the Capacitor if you look closely H(Compressor) C(Common) & F(Fan) will
be stamped on top of capacitor. You will have to follow the wires back, my guess is blue
could be the compressor, yellow probably the fan and brown the common. the to yellow
wires are probably hooked to each other and can be changed if the motor starts up the wrong
way. Follow the wires back to each component to double check

I need to know how to wire up a 4 wire motor to two capacitors. Also, i have a 45 MFD 440 VAC and a 5x370 i need to which one is for the compressor and which one is for the fan?


Each motor, compressor have there own capacitor, The 45uf is for the compressor and the 5uf is for the fan motor. If the motor has two brown wires and a black wire, white/or yellow wire the brown wires go to the capacitor and the other two go to the contactor for power. Black to common side of contactor (black)and the other to the red/or yellow side of contactor.

Does a gemtech 40 + 5 mfd work with a comfortair


Hi, as long as the 40uf x 440 volts and 5uf x 440 volt capacitor are the same is what you are replacing, yes it will work. Don't replace this 40 uf x 440 volt with a 40 uf x 370 volt cap. Voltage and microfarads must be the same, brand name makes no difference or these numbers, only the uf and voltage. Must be a 40 uf x5 uf, 440 volt dual run cap. It will work if the unit you want to put it on calls for that cap. The comfortair is a 3 ton unit, just be sure it takes a 40x5x440 volt and it will be fine.

My comfortmaker a/c fan does not work. compressor sounds as though it is trying to cycle on or off


sounds like a bad capacitor. if you can spin the fan blade and it starts turning on its own and every 30 45 sec the compressor sounds like the compressor is trying to start you will need to replace the capacitor. if you remove the panel to expose the electrical controls. the capacitor is the large round canistor looking device. its rating will be stamped on the side, its probably a dual cap if both the fan and compressor arent starting in which case it will have three posts on top and the value will be listed like this 45-5-370or440 that would be 45uf for the compressor 5uf for the fan and 370 or 440 volt. on the top of the cap you will see C,FAN, and HERM, you must make sure the wires go back on the new just like on the old you also must make sure you capacitor rating of the new cap is the same rating as the old. post with more info or other observations and i will continue to help you if you need

I HAVE A GOODMAN CK-36-1A AC AND THE FAN IS NOT WORKING. WAS TOLD TO REPLACE THE CONDENSER CAPACITOR AND IF THAT DID NOT WORK REPLACE THE THE CODENSER FAN MOTOR. THE COMPRESSOR COMES ON BUT SHUT DOWN WHEN...


Goodman unit you can use a 1/4 hp or 1/3 hp cond. fan motor but it does sound like a cap. Replace cap first. Its very easy to do just open up panel and replace the silver bullet with terminals out the top. It will say on the side what size it is like 40uf 5uf or something like that. Thats most likely your problem. Russ
