Hello All,

Looking for advice from someone who has actually worked on this model A/C unit. Symptoms are Fan runs, but compressor either strains or starts for a few seconds, and cycles on/off at regular intervals. I downloaded a manual from this forum (the odd/even page manual) but it shows a separate start and run capacitor. I found one large capacitor on the left rear side, just behind the compressor. It is oval and about 10 inches by 4 inches by about an inch wide. It has 4 terminals, and looks like 3 caps in one. The side of the cap calls out the 4 terminals as com, fan, fan, and Herm. 7.5, 7.5 and 30 uf. I assume that the Fans are for the condenser and squirrel cage fan motors, and the Herm is for the compressor.

The manual (wrong model) shows a start cap, but I cannot find it on the outside of the unit. I have not removed the inside shroud yet, or opened up all the sheet metal up outside yet, but cannot imaging why the cap would be anywhere else than near the compressor.

I have a neat cap checker at work, that will run rated voltage through each terminal, and report actual capacitance, so I'm taking the cap I found in and see if the three internal caps are O.K.

I need the advice of someone who has worked on this model before. Should I be looking for a start cap, or does this unit have a combined start/run cap, labeled herm?

Any other advise would be appreciated.

Thanks!! It sure is getting hot out. If it is a cap. relay, or something easy, I'll try to save it. If it is the compressor, I'm gonna roll the whole unit right off the top, and replace it.

Overall, the oher parts look O.K. for being 39 years old.

Thanks again for the help!!!
