Hi! I have a problem reinstalled a capacitor fan motor from my air conditioner,the brand is Intertherm I brought new capacitor (35+5 MFD)370 VAC but I confused about the wire conection do you have some web page where I can see the wire conection Thanks .

Re: reinstall capacitor 370 vac from a/c
Here is the standard connection of dual capacitor. Actually you can see the diagram on the unit but Im not familiar with the Intertherm model. What can I give to you is only the standard connection of dual capacitor.

the three post capacitor has c for line voltage in, the f or fan is for the outdoor motor,and com or comp goes to start winding compressor.youll have to follow wires from indoor motor to find capacitor. to find wires to outdoor motor to capacitor you have line voltage and capacitor wires .look for schematic it would help or send colors of wires from both motors and compressor common,start .run.
I tried to cross the model number you passed without success. Capacitors are not model specific. They are specification specific. On the side of the capacitor there is data printed on it like 370 V
35 / 4 Mfd That is the data you need to get a replacement. If you do a net search for example of
Capacitor 370 V 35/4 Uf You will get many results and sources. Find that data on your capacitor or please let me know what geographic location to search for your air-conditioner parts. This model number does not appear to be a US model. If you respond with the model number even if it is the same I will find it. Just tell me what geographic region to search.
You need to check the Amp draw at start up of the compressor. Also if you have a meter that can check the compressor capacitor, it needs to be checked. If the capacitor is ok and the compressor starts at a higher Amp draw than the rating on the capacitor, you will need a start capacitor.
That system uses a 40+5/370 capacitor. The Intertherm part # is 620888. You can also use a 40+5/440 cap. You can pick one up at a local dealer or distributor, or order online. Look at spending about $15 for the capacitor.
