sears compressor conversion

daleosinski

I have a dual voltage compressor and it is currently 220. What wires do I change to make it 110?

SwiftyMcV

Well

1) give us the amperage or wattage rating for it @ 240V and 120V

2) Then tell us what GUAGE the wire feeding it is.

then I will be able to tell you exactly what you need

Dale the diagram to do this should be on the motor nameplate or in the wiring compartment of the motor under the enclosure lid. If you have no wiring diagram this is a risky procedure and if done incorrectly can burn up your motor. Can you post a picture of the motor name plate and diagram if you can find it? Can you give us the model # and maybe we can get the diagram for you from an internet source.

Dont forget man going from 240V to 120V will mean a higher Amperage and if he plans on using an existing circuit he may not be able to without running a new, bigger feed. Thats why I am asking that.

There is no diagram that i can find but the model no. is 919.152920. It is dual voltage and it says a kit kk5056 has the info but I can't seem to find any diagram.

Stubbie

Why would I repeat what you already asked?

Care to point it out?

Stubbie

Dale I can't find the wiring conversion diagram and that kit may be necessary to do so... you can order it here......put in the model number you gave me then look at the parts list as asked.

There are two types of single phase dual voltage motors listed by NEMA.

1) Dual Voltage (main winding only)
2) Dual Voltage (main & auxiliary winding)

I will provide you with both at low voltage (120 VAC)

Wire number and color conversion as follows:
1) Blue
2) White
3) Orange
4) Yellow
5) Black
6) No color assigned
7) No color assigned
8) Red
PI) Brown (OL)
P2) Brown (OL)

1) Dual Voltage (main winding only)
(ccw) (L1) - 1,3,8 (L2) - 2,4,5


2) Dual Voltage (main & auxiliary winding)
(ccw) (L1) - 1,3,6,8 (L2) - 2,4,5,7


To change rotation on either one interchange #5 and #8.

If the capacitor leads are exposed you will need a diagram. This information is directly from the NEMA Hand book.
"Terminal Markings and Connections". Single Phase Motors-Capacitor Start.

You may be able to figure this out by the difference in the amount of wires for each motor!
If you are not comfortable, check out a local motor shop. They can show you how.
