Many years ago, I rewired the 110/220v motor (GE) of my Craftsman air compressor to run on 220v power. Worked fine until just recently: It wouldn't turn on (although I can easily rotate the motor shaft manually). So, one by one, I replaced the check valve, both capacitors, & the pressure switch. Still won't start. Using a multimeter, I confirmed 110v power in each of the 2 power legs to & through the On/Off switch & even at the connection terminals on the motor itself. So I concluded the motorcitself is shot & that all I can do is replace the motor or just buy a new compressor. Either will cost more than I'd like to have to spend.
Then it occurred to me that I had read somewhere that these motors are dual voltage because they have 2 sets of internal wirings, rather than just one set.
So now I'm wondering if the motor might work if I just change the motor's wiring back to work with 110v current instead of 220v current?
It's not much trouble to rewire it ( I still have those directions), but I'd also have to buy & install a new 110v cord & plug.
Of course, I don't want to waste either my time or money if there's no way this might work. So I'd appreciate others' thoughts.
So, if I'm right about the motor having 2 sets of internal wirings, then I'm guessing both are required for 220v & only one is required for 110v, so maybe only one wiring set is at fault & preventing it from starting under 220v power. If that's right & if just one of the 2 sets of wirings is damaged, then it seems like I'd have a 50% chance that the other set is still good & might allow the motor to run using 110v power. On the other hand, I'm no electrician or electrical engineer, so my assumptions about all this easily may be wrong.
So I wanted to see if someone might be able to tell me whether there's any actual chance that returning it to run under 110v power might bring this motor back to life?
Thanks
