I Have read a couple of threads that seem to present a problem similar to the one on my sidebyside unit. That is my unit cools upon first connecting the unit to a live outlet upon startup but then never again seems to force itself into cooling again but you do hear the click, click, click of the unit attempting to place the compressor back into cooling again. Deduction and process of elemination places this problem for me as one caused by relay activating the compressor or at the compressor damage. One of the messages stated that the relay on the unit was white however the Tech sheets corrected this information for the particular model I have. The relay (labeled on the sheet as a PTC relay is black; it has blue and white wires connected to the unit and this is where I conducted the continuity test as described in resolving the problem in one of those threads above. At the 200ohm scale the test shows as an open. I conclude the relay is damaged as it also rattles; the second tech sheet is a drawing which shows a variable resistor running in between the test points for continuity on the outside of the PTC relay; this would be the connectors used for the blue and white wires. Is my conclusion correct, that is, the relay is likely the damaged part?
As for what is white next to the relay that would be the overload I am not sure on how to test this part but will assume is good for the time being my question here would be
Is it standard to replace this part in conjunction with the PTC relay?
Can I safely assume that the compressor is in good shape being that the unit cools upon startup (twices started and it reacted similarly) or do I have to test the compressor --somehow force it to start to verify it works before repairs?
The Embraco web site is not very specific as to describing the particular compressor so if anyone can provide more detailed info so as to attempt to force the compressor to start it would be appreciated if you post/reply. In particular I wanted to find out the horse power rating so as to determine if it was possible to purchase a 3 in 1 starting unit to test the compressor's operation. Markings on the unit (EGS, HLP) when used in a web search only return web sites with no technical info only sales related so far..
One further question if I may, is there a local to Houston or close to downtown area where I can purchase this part or for that matter any refrigerator parts for this unit, I also need the door gaskets for another unit my backup.
Any help appreciated thanks .....
