Mach 15 A/C Fans Intermittent - Fixed
#1

Number 1 & 3 rooftop A/C unit fans would start-stop-start-stop-start & run.  Both units started doing that on the same day.  I checked the fan capacitors, they were out of tolerance.  Then I found an intermittent start capacitor and a run capacitor out of tolerance.  I ended up replacing all four A/C units fan (7.5uf) and run (40uf) capacitors and replaced the 4 start capacitors & PTCR's with Supco SPP6 .  Then I cleaned the evaporator coils and condenser coils.  I checked the compressor terminals, they were good, it's not uncommon to find an overheated terminal on the compressor.  I move the terminal back & forth to ensure a good connection.  I spent wo days on that project, hopefully it cured the intermittent fan problem.
