Goodman Heat Pump Error Code 06

Error code 06 on a Goodman heat pump indicates an open start circuit in the compressor. This means the control board cannot detect proper continuity through the compressor's start winding. The cause may be a failed run capacitor, a wiring fault, or an internally open compressor winding. A technician should test the capacitor and wiring before concluding the compressor itself has failed.

Resetting the unit by cycling power may temporarily clear the fault and allow a restart attempt, but if the underlying cause is not corrected, the code will return quickly. An open start winding or failed capacitor will continue to prevent proper compressor operation, and repeated failed start attempts can cause additional damage. Diagnose and repair the root cause before relying on a reset.

Repair costs vary significantly depending on the root cause. Replacing a failed run capacitor is generally the least expensive fix, typically ranging from around $75 to $250 including labor. Wiring repairs fall in a similar range depending on the extent of the damage. If the compressor itself has an open start winding and requires replacement, costs can range from $1,000 to $2,500 or more depending on compressor size and local labor rates.

Some causes of error code 06, such as a loose wire at the compressor terminal block, can be addressed by a knowledgeable DIYer who is comfortable working around high-voltage electrical components. However, testing and replacing a run capacitor or diagnosing a failed compressor involves stored electrical charge and refrigerant system components that are safer to handle with professional training and tools. If you are not experienced with HVAC electrical work, a licensed technician is strongly recommended.

No. Error code 06 indicates the compressor cannot start properly, and the system locks out for this reason. Attempting to force the unit to operate without addressing the fault can cause the compressor motor to draw excessive current, which may damage the compressor, the capacitor, or associated wiring. The unit should remain off until the fault is diagnosed and repaired.
