Advice in changing from 120 to 240Volt power supply

I have a Sears Air Compressor model 919-15294 with 120/240V motor. I have been running it on 120V and now have a 240V outlet available. Is there anything I have to do other than change the plug to match the 240V outlet socket?

_________________
I expect, if the motor is wired for 240, that you'll need to alter the wiring, but I'm not sure. And, a wire for a 120 volt power supply would not be the wire I would use to handle a 240 volt supply. I hope an electrical guru can comment for you.

Cheers,

Bill

your compressor should have the instructions for switching the wire connects to their correct spade connectors inside the metal cover that houses the wiring.also,the attached cord is designed to handle 220 volt,so all you have to do is move two or three spade connects.i cant remember which without looking,but it's really no problem to change.then just put a 220 plug on end of cord,if necessary, and you're in business.

Low end air compressors are made by the thousands offshore, using the cheapest parts possible.

It sounds to me like you need to replace the pressure switch, around a $30 part. That might be better than buying a whole new air compressor.

Good luck,

Bill
