So possibilities: The fan is in bad shape and somehow blew the new capacitor; The fan was damaged by the previous bad capacitor, ran for a bit, but now won''t even start with a good capacitor
Customer ServiceThe capacitor gives the initial jolt of energy, and when it fails, the AC unit struggles to start. A common workaround, albeit sometimes dangerous is to give the fan blade a jump start with a stick. This can be dangerous and cause damage to the unit, so should only be done in the case of an emergency.
If the capacitor goes bad, then the condenser fan won’t spin. You might also hear a humming noise come from the condenser fan—that’s another sign that the capacitor is bad. But a bad capacitor isn’t the only thing that causes a condenser fan to not spin.
Examine the capacitor: Wear gloves and safety goggles, then do a visual inspection. A faulty capacitor often appears swollen, bulged, or might even show signs of leakage. If you notice any of these signs, it’s a clear indication the capacitor needs replacing. Check the fan motor: Manually spin the fan blades.
Regardless of the exact lifespan, the capacitor is likely to be the first part to fail on an AC unit. Once the capacitor fails, the fan can no longer start spinning. ACLAB Note: As I stated, capacitors hold an electrical charge even after the unit has been shutdown.
The most common symptom of a bad capacitor is humming from the condenser fan motor on the outside unit, or the motor will not start. In the home, you will notice that cold air is not coming from the vents. When this happens, the capacitor is not functioning and cannot deliver enough stored energy to run the fan motor or compressor.
When the system is trying to do something that needs more energy, a bad capacitor can cause issues. This symptom might also show up as the unit taking a long time to start working after you turn it on. The capacitor gives the initial jolt of energy, and when it fails, the AC unit struggles to start.
