Check: Turn off refrigerator main switch, then attempt to re-close breaker
What to do: Turn off refrigerator main switch, then attempt to re-close breaker → If it immediately trips again, inspect for short/ground fault → Re-verify breaker capacity → If ELCB/RCD, investigate ground fault cause
ELCB/RCD operated due to ground fault

The circuit breaker is off or tripped. Before re-closing, always identify why it tripped. Repeatedly re-closing a tripped breaker without finding the cause poses a fire risk.
