Why Isn''t My Outside AC Unit Turning On? 6 Causes and Fixes
This should include a full inspection of the blower, fan, compressor, drain line, and capacitor. If the outside AC unit is working properly, the compressor and capacitor will help to power and control the operation of the blower and fan, which should then work in tandem to remove heat, while the drain line handles any excess condensate.
How Long Do AC Capacitors Last? (And Reasons Why They Fail)
5 Reasons Why AC Capacitors Go Bad. Short Cycling; Too Much Heat; Wrong Voltage Or Rating; Old Age; Storms and Power Surges; Reason 1: Short Cycling. An air conditioner that short cycles, cycles on and off too quickly, is a major reason for capacitors to fail prematurely.. Short cycling is bad for all A/C components, but the strain …
