Central Air Conditioner Parts

OEM Central Air Conditioner Parts

When your central air conditioner stops cooling or won't start, the culprit is usually one of five parts. Run capacitors fail silently—your compressor hums but won't turn over. Condenser fan motors burn out from heat stress, leaving the outdoor unit unable to shed warmth. Compressors themselves occasionally fail after years of cycling. Starter solenoids click but don't engage. Thermal fuses blow to protect the system from overheating.

Repair Clinic stocks genuine OEM replacements for, and the entire family (, ) plus ecosystem brands. Find your model number on the unit's nameplate—it's usually on the condenser cabinet or indoor coil housing.

• Capacitors (run/start) – Unit hums but won't start or cycles off randomly
• Condenser fan motors – Outdoor unit running but not cooling; loud grinding
• Compressors – No cooling output; warm air from vents
• Starter solenoids – Clicking sound; compressor won't engage
• Thermal fuses & breakers – Unit won't power on after shutting down

Central Air Conditioner Repairs: Your Questions Answered

Why won't my or air conditioner start?

The run capacitor is the most common culprit. It stores electrical energy to jump-start the compressor and condenser fan motor. When it fails—often silently with no warning—the compressor hums but the shaft won't turn. You may hear a buzzing sound or smell a burnt odor near the outdoor unit. Replacement capacitors are inexpensive and solve the problem 80% of the time.

My or AC is running but not cooling. What's wrong?

Check whether the condenser fan (the large fan in the outdoor unit) is spinning. If it's not rotating or grinding, the fan motor has likely burned out. The compressor can run, but without airflow across the condenser coils, heat cannot escape and the system shuts down on a pressure switch. Condenser fan motors are wear items and a straightforward replacement.

How do I find my central AC model number?

Look for the nameplate on the outdoor condenser unit, usually mounted on the side or back panel. The model number is printed clearly—write it down exactly. If you have an indoor air handler, check its nameplate too; some systems use both model numbers. Enter the complete model into Repair Clinic's parts finder to see all compatible parts, then confirm OEM part numbers match your brand.

Are family parts interchangeable between, and?

Many capacitors, motors, and solenoids are shared within the ecosystem, but not all. Always verify the part number on your existing part and match it exactly when ordering. A slight variation in voltage or microfarad rating can cause failure or safety issues. Repair Clinic's parts lookup automatically cross-references brands and shows you the correct OEM match.

Narrow Central Air Conditioner Parts to Your Exact Model

The fastest way to the right central air conditioner parts is to start with its model number. Check the exterior nameplate on the outdoor condenser cabinet, especially the side or back panel.

This model number applies to the entire unit, not just one part, so you can narrow everything from electrical parts to cabinet hardware. A precise match helps you avoid compatibility guesswork and move through the repair with confidence.
