Adding a Capacitor

When I bought my second 1950 Frigidaire model DM-90P it didn't work. The seller said it was "dead", wouldn't do anything. I bypassed the compressor relay and got it running. After a couple hours the evaporator was fully frosted. So I replaced the relay. It ran fine but every once in a while I'd hear a loud start and sometimes the overload would trip. So, I kept an eye on it. This went on for quite a while. I found no rhyme or reason to it. There was no pattern. Then one morning the compressor kept repeatedly trying to start, loudly, and the overload kept tripping. I unplugged the fridge and went to work. Nine hours later, when I got back home I plugged the Frigidaire back in and got the same result. So I knew it was an electrical problem. I had been thinking about the, original, wiring going from the relay to the compressor. Maybe there was an intermittent bad connection. So I replaced that wiring. I found a black, flat, three wire extension cord on Amazon that is a perfect match to the original "Rip-Cord", as Frigidaire called it. I cut it to the correct length, crimped connectors on both ends, and installed it exactly as the original wiring was. Once again the Frigidaire ran fine for a while but it started acting up again! Same thing, occasional loud starts with occasional overload trips. Now I began thinking it must be a hard starting compressor. I remembered reading in my 1950 Frigidaire Parts Catalog about an "optional" capacitor "if needed". I didn't want to use a modern hard start kit, or anything modern, on the Frigidaire. I wanted to fix it like a repairman from that period would have. The Catalog gave a part number, but more importantly, the specific capacitance that would be needed. Amazon came to the rescue again. They had the correct start capacitor and, what looked to me, the correct style for the period as well. I installed the capacitor in series between the start (S) terminal on the relay and the start wire for the compressor. It's been working like a charm! Nothing but smooth quiet starts for the past month! I bought a clamp and mounted the new capacitor behind the chrome kick panel. I used one of the screws that was already there holding the bracket for the kick panel. I believe this was a decades old problem with this refrigerator since the relay I replaced had a 1962 date code on it (62 002) and the cold control was replaced at some point as well, the knob is a later 50s style. This has been a saga but hopefully it will help someone else who may be having the same problem.
