Hi,
New here so I'll try to be quick.
I installed a compressor that I bought from coldparts.com in an old True freezer unit that I carted off when I sold the guy a new one. The compressor was advertised as a Tecumseh AEA2424Z with 2800 BTU @ -10 deg. When I installed it did not cool below about +30 and I noticed that it had very high head pressure. I assumed plugged cap tube but when I took if out it seemed fine. Looking further into the compressor side I noticed that what I received was a CAE2424Z so I called Tecumseh and they said it's a European style and the numbers don't mean the same as in the states. In the end he said it was about 1900btu @ 10 deg. Also when I went to replace the capillary tube, Supco says 29", but the existing tube is about 70" though.
My question is could this long cap tube combined with an undersized compressor be source of the high head pressure and poor cooling? Or if the cap is clear would it work okay and just not have the cooling power of the bigger unit? One more thing, the compressor was smaller than the original but I wieghed in the factory charge so it may have been slighty overcharged as well.
Thanks for any insight!
