Title: Roof A/C
Post by: Roy Boles on August 03, 2022, 01:52:20 AM

Hi everyone. The rear A/C compressor is not coming on when the unit comes on. All the capacitors were replaced two to three years ago. I did a visual inspection. Watch one starts the compressor? The large or the small one.     
      I know, it’s probably time for a new ones. I would love to get one more year out this one.

As I recall, the small one is usually the Start Cap.

a run capacitor only has one UF number like 40 or 50  stamped on its case the start cap has two like it has A range and are much higher numbers .
