Craftsman / GE Air Compressor - Cannot read the Motor Start Capacitor Info (MFD, microfarads)

hello Builders,

Recently the Starting Capacitor blew on my dear old air compressor.  unfortunately, the Capacitor, Mepco/Electra, used a ‘paper’ specification label, and it has been mostly worn off.

After calling TEMCO, I have been informed that without the nameplate information on the capacitor, they cannot recommend a replacement.  Specifically the MFD information.

Hail Mary - 

if anyone has an air compressor w a 220V GE motor (model C-MO-3003 / 5KCR48SR41W), I would love to know what your 5HP-1Ph starting capacitor says.   This is a $20 part which is stalling me out.

Thanks in advance.

I would imagine the start cap. would be under 200uf at 300v. But there are capacitor formulas available on the web to calculate the exact uf.

good luck


I needed a part for a GE motor a few years ago and was able to make contact with someone at GE who fixed me up.  You could try contacting them:

You would probably get a faster response from a local electric motor repair shop.  It looks like you are in Utah.  A quick google turned up this shop:  There are other electric motor shops listed on the yellowpages website.

Hope you get it fixed.
