Goodman Air Conditioner Error Code br

The br code on a Goodman air conditioner stands for Brown Out Protection. It means the unit detected that incoming electrical voltage dropped below the safe operating threshold and shut itself down to prevent damage to the compressor and other components. The unit will remain in this protected state until supply voltage returns to an acceptable level.

Resetting the unit may temporarily clear the br code, but it will return if the underlying voltage problem is not resolved. If supply voltage has returned to normal, the unit should restart on its own or after a reset. A recurring br code points to an intermittent or ongoing low-voltage condition that requires investigation.

Cost depends heavily on the root cause. If the issue is a utility problem or a simple loose connection, the fix may cost little to nothing. Breaker replacement typically runs in the range of $150 to $300 including labor. If wiring needs to be upgraded or a control board needs replacement, costs can range from $200 to over $600 depending on the scope of work and local labor rates.

Some causes are DIY-friendly, such as checking and tightening loose connections at the disconnect box or identifying an overloaded circuit. However, if the issue involves utility voltage problems, damaged wiring inside the panel, or a failing breaker, a licensed electrician should handle the repair. Always shut off power to the unit before inspecting any electrical connections.

No, you should not attempt to force the unit to operate when the br code is active. The brown out protection exists specifically to prevent compressor and motor damage that can result from low-voltage operation. Running a compressor under low voltage causes excessive current draw and heat, which can lead to premature compressor failure.
