Electrical mysteries can be real head-scratchers, but our Keep Smiling detectives love a good challenge! When this family's HVAC system started acting like it was on a power diet (fluctuating between 246 and 100 volts), we rolled up our sleeves for some serious investigating. After load testing the entire system and ruling out recent work, we discovered the culprit hiding in plain sight - a burned-out 50-amp breaker connection that was literally getting toasty with the bus assembly. Lucky for this family, we caught it before any major damage occurred. One clean-up job and new breaker later, their AC is back to steady, reliable power!
