I ordered a new start relay (PTC) for a refrigerator and when I tested it with the ohmmeter between terminals 2 and 5 I got no sound or reading, just OL. but got a good reading between the common on front and the L blade on back (less than 1). On autorange M ohm setting, the next highest on my multimeter after sound setting, it climbed to 40 and then OL. It is the enclosed type with interior coil and I have read a number of places that a good one shows less than 100 ohms between 2 and 5 and usually just a few ohms. I tried the relay on the compressor anyway and it did not work....surprise. I ordered another one from a different place - exactly the same - and when I got it it tested the same - so I did not use it. As far as I know it is the right part according to the look up tables for the model (Embraco 51306008/CLS30820101)- a replacement for the original part that was discontinued (Embraco 513604039). Correct hookup was verified also. And, I used another meter and got the same readings and tested another new one that is not for my refrigerator and it tested sound positive and showed 6 ohms or less.I did shake them lightly but no rattling although there is a very light sound of movement but not like loose pieces more like a springy sound and is the same for the good one. One thing I did notice though is that with the good one, which was considerably smaller, I got a reading much closer to the openings while the bad ones were a bit deeper - I do not know if this is a size-related thing or has any significance. This start relay is too expensive (around $100 or more especially with fast shipping) even if it did work and looks really cheaply made, but it still seems unlikely I would get two bad brand new relays from different vendors unless both were from a bad lot -but it seems to be the case or am I misunderstanding or missing something in my assessment? Any thoughts and / or guidance would be appreciated.
