I'm again having the problem of my roof A/C compressor running 3 or 4
seconds and cutting out. The RUN capacitor was replaced with a used one.
It worked fine for a few days. I can remove the wire which we "THINK" is
from the compressor overload switch and the unit works fine. The
compressor actually gets quite cold in operation. Is this normal?
Do I have a second bad Capacitor?
Could the compressor overload switch be bad?
could the relay be bad?
I don't have the time delay so many have mentioned. Where can I get the
"Mars" or equivalent relay?
Thanks Again, Tim
