How to Fix Refrigerator Error

1. Verify household electrical power is restored. Check circuit breaker panel to ensure refrigerator’s dedicated 15-20A breaker is fully ON.
2. Measure voltage at refrigerator outlet with multimeter during operation—must maintain 110-120V AC.
3. Inspect power cord and terminal block connections inside refrigerator for looseness, corrosion, or arcing damage.
4. Tighten terminal block screws to 8 in-lbs torque if accessible and loose.
5. Ensure refrigerator is on dedicated circuit with no other high-draw appliances sharing the line.
6. For recurring voltage issues: install whole-house voltage regulator or dedicated UPS for refrigerator circuit.
7. After verifying stable power, restore refrigerator operation.
8. Run temperature monitoring for 24 hours to confirm normal cooling performance.
9. If error recurs with stable voltage, suspect main control board fault requiring professional diagnosis.
10. Document voltage readings during multiple compressor cycles if problem persists for technician reference.
