Safety first: Turn OFF power at the outdoor disconnect and verify with a non-contact tester. Capacitors can retain charge.

Inspection steps:

1. Check for obstructions: Look through the top grille of the Tempstar condenser. Remove any sticks, plastic, or debris blocking the fan blade (with power off).
2. Spin test: Gently spin the fan blade by hand. It should move freely. If it is stiff or grinding, the motor bearings may be seized.
3. Inspect wiring: Remove the electrical panel and verify the fan motor wires are securely connected to the contactor and capacitor. Look for burned or broken wires.
4. Observe startup: Restore power and call for cooling. If the compressor runs but the fan does not start, shut power off again to avoid high pressure.
5. Likely repair: A failed fan motor or capacitor will need replacement. This involves disconnecting and rewiring the motor and should be done by a qualified technician.
