Goodman mini-split or inverter condenser shows E3 and outdoor fan or compressor will not run

Safety first: Turn off power at the outdoor disconnect and breaker. Wait several minutes for capacitors to discharge before touching components.

Steps to check:

• 1. Inspect fan blade: Remove the top grille of the Goodman condenser. Check for debris (sticks, leaves, plastic) blocking the fan. Spin the blade by hand; it should rotate freely without grinding.
• 2. Check wiring to fan motor: Locate the fan motor harness where it plugs into the outdoor PCB. Ensure the connector is fully seated and wires are not damaged or pinched.
• 3. Look for burnt components: Inspect the outdoor PCB for burnt spots, swollen components, or discoloration around the fan drive section.
• 4. Test fan motor (if equipped with capacitor): On non-inverter models, check the fan capacitor (often shared with compressor). If the top is bulged or leaking oil, replace the capacitor with the same µF and voltage rating.
• 5. Attempt restart: Reassemble, restore power, and call for cooling. If the fan still does not start and E3 returns, the motor or board is likely defective.

When to call a professional: Replacement of a DC inverter fan motor or outdoor PCB requires proper part matching and electrical safety; have an HVAC technician perform this repair.
