york y cal
looking at a york and its been a while
system 1 is alarming sensor failure
system 2 runs for about a minute ,shuts down then goes on to ar timer
is there a problem on sysem two or is that normal?
is the sensor failure a sensor fault or could it be because system has problems with refrigerant? (suspect short as there is oil around sightglass but still liquid in liquid line)
