I know that disconnect P!ssed me off! This particular unit was a no cool call! Found the return fire damper shut! Pressures and temp about normal if it was 76° inside the conditioned space! But, it was 88°! Found a big hole also in the return past the damper allowing a little bit of hot airflow threw! But, not enough!
I got to admit! Carrier has built a good unit before! This relic appeared to be all original! Dual shaft condensor/blower motor finally gave up the ghost after what?42 yrs or so? Owner said to fix it! So i did!
