cap size
One of my cooler compressors is down...
I want to replace caps before calling the HVAC guy. I found the run cap is 35 MFD The start cap print was dim and dirty so I tried to rub the label. It came apart  The cap is 2 1/2" diameter, 4 1/4" high on a 2hp refrigeration compressor. Very partial label: ???? TRAL AB ???? 4576BC8 What size cap should I try? Karl |

Find the compressor model number, Tecumseh and Copeland both publish their cap sizes IIRC |

At least you got it working. What size cap should I try? Karl -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |

It's a little late now, if it was too much or too little something expensive will have broken by now - But... Reading the old capacitor nameplate is irrelevant. The compressor nameplate is usually stamped steel or something else equally indestructible, and most likely still legible - you can look up a data sheet on the compressor and it'll show the capacitor needed. |
