Trouble with LG Compressor

[Kompulsa]

Hello.

I got a working 120 volt LG LX67LAQG refrigerator compressor that has a power consumption of 177 watts, but in LG's compressor spreadsheet, the required start/run capacitor field is blank.

I called them today and they kept transferring me back and fourth and failed to tell me what size start/run capacitor the compressor requires. My 35 uF air conditioner start capacitor worked, but I fear it is too big for this compressor.

I used this calculation suggested by someone in another closed thread to try and determine it:

(2650 x Full load amps ) divided by supply Voltage = MFD

177 watts / 118 volts = 1.5 amps. 2650 * 1.5 amps = 3795. 3795 / 118 volts = 33.6 uF.

Does anyone know if I can safely use that?

That is the same PDF they sent me. It isn't there.

Thank you for trying, though.

With the useful information IM gave you, you should be able to tell it's a RSIR motor, so doesn't have any type of capacitor!


Maybe learn about motors a bit before using formulas, maybe look at this http://www.embraco.com/DesktopModule...vos/MP01EG.pdf

Thank you install_monkey and paul_h. You have saved me a lot of trouble.

I just plugged in the LG directly and it worked with no capacitor.

Now I need to get the other details about evaporator temperature and so on, but can't get a datasheet.

Btw, the capacity is rated at 217 watts. Does that mean it is 1/4 HP or 1/3?

Also, it says it is a temperature of -23.3. I guess that is celsius?
