What happens if AC capacitor goes bad?
A bad capacitor prevents the exterior unit from properly functioning, which hinders the cooling process as a whole. Second, improper voltage delivery to exterior unit components forces the system to work harder as it attempts to perform its job. Additional components often sustain damage due to a faulty capacitor.
Will AC fan run if capacitor is bad?
The simple answer is “No.” There are two types of capacitors–the start capacitor that signals the AC motors to start up, and the run capacitor that keeps those motors running through each cooling cycle.
