What to do if my GE Concord 4 says 'AC POWER FAILURE'?
- GgsmithAug 19, 2025
If your GE Security System displays an 'AC POWER FAILURE' message, it indicates that the panel power transformer might be unplugged or there could be a power outage. If the transformer is plugged in, check the circuit breaker or fuse that controls the outlet.
