Controls don't work properly — buttons, switches, or displays may not respond.
-
Circuit breaker keeps tripping — could indicate a short circuit or failed component inside the box.
-
Burning smell or visible discoloration — overheated wiring, relays, or circuit-board components may be damaged.

Buzzing, clicking, or unusual electrical noises — a relay or contactor may be failing.

Loose, corroded, or burned wiring/connectors inside the box.
