Hello,

I recently purchased a Westinghouse WD12 Coca-Cola cooler.  It was in pretty good shape and was complete, even including the original compressor tag still attached.  It was not working when I purchased the cooler.  I replaced the power cord and the compressor runs, the condenser fan runs, and the coils of the evaporator get cold.  The evaporator fan does not run.  I read the post on replacing the evaporator fan and the directions are great.  I do have a few questions though.  There is a part wing nutted to the top of the compressor that I have no idea what it is.  The red wire from the evaporator fan runs to this part.  And a black wire also runs to it from the terminal block.  The bottom of the part is stamped 220VAC doubler?'<img'>?(that is all that I can make out through the rust).  According to the "Electrical Connection Chart" that is on the compressor tag this part is a "3 Mfd. Capacitor".  My questions are:  What is a 3 Mfd. Capacitor  and will I still need it if I install a new evaporator fan?  Could the 3Mfd Capacitor be bad or is it more likely to be the fan motor?  I have attached a picture of the refrigeration unit and the part in question is visible on top of the compressor.  I would greatly appreciate and help and info.

THANKS,
David

That would be your old evap. motor's start-capacitor, it will not be needed when you replace your old unit with a new motor as it is a two-wire (as opposed to three/split-phase) motor. here's a picture to help explain.

Hello,

Thanks for the fast reply.  With my questions answered, and better understanding of "whats what" I am going to try to get the cooler working this weekend.  I will post back with my results.

THANKS AGAIN,
David

Hello,

Thanks again for the information.  I replaced the evaporator motor with a similar 1550RPM CCW rotationmotor and re-installed everything into the cooler.  After running for about 15 minutes the temp. inside the cooler had dropped to 22 F and compressor was still running.  I have not installed the baffles inside the cooler yet.  Im hoping that I can make some adjustments on the thermostat to regulate the temp.  

Any suggestions????

THANKS,
David
