The Bryant outdoor unit fan runs, but the compressor does not; no cooling is produced.

Safety first: Turn off power at the outdoor disconnect. Compressors operate at high voltage and can be dangerous.

Steps:

• 1. Listen for compressor: With power on and a call for cooling, listen for a humming or clicking from the compressor. A loud hum followed by a click suggests it is trying to start but failing.
• 2. Inspect capacitor and contactor: With power off, check the dual run capacitor for bulging and the contactor for burnt contacts. Replace as needed (see capacitor entry).
• 3. Check wiring to compressor: Inspect compressor terminals and wires for burns or loose connections. Do not touch terminals directly.
• 4. Professional diagnosis: If the compressor still does not start after capacitor/contactor checks, a technician must test the windings and possibly install a hard-start kit or replace the compressor.
