"soft start" for fridge?

[Ronnie]

I saw on a post about a/c that there is a device to "soft start" the compressor so start up load is less amps. Has anyone done this with their fridge?

My fridge is a 4.7 cu ft mini fridge. It draws 40 watts or so running,or about 4 amps. Start up is 50 amps 12 volt DC,( not 50 amps 110 AC) at the inverter. I would like to get the start up load down a bit if possible.

Yes it is opens big in a separate screen when clicked.

I'm thinking it works the same way that is used on the "soft start" A/Cs. It reduces power draw, on the compressor, at 1st "grunt."

Thanks typed it in and got it.

How will this work with a fridge? Basically the idea should be just fine, however I assume it(soft start) has capacitors to start the load, so would one for a/c be sized good for a fridge? Seems that it would not?

I have a three phase starter for my milling machine and lathes and it is sized for the motor hp and works great for the correct size motor. For my small mill the motor is too small for the size of the starter so I put a larger motor on the floor to use to balance the load and help create the third phase. I know the phase converter uses capacitors and sizing is important. So with this thinking in mind I am wondering if the same rules apply to the fridge?

a hard start capacitor for a small window unit or a PTAC might very well work..

Maybe research/try a 3 in 1 capacitor's that are made for fridges.

Looked up hard start capacitors, and it seems that should work, so will order one and try it out. Might just try it on a small window a/c unit just in case I goof and fry something. Have an old one laying around, better that then my fridge. Then put it on the fridge once I am sure of what I am doing.

Thanks fellows
