Problem: Flash code 7: Power supply fault (non-display models); voltage instability or temporary outage

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.

Problem: Alternate representation of heater circuit fault; identical failure mode to HE code

How to Fix Dryer Error

• UNPLUG dryer from electrical power and allow 45 minutes for components to cool completely.
• Remove rear access panel to access heating chamber assembly.
• Disconnect electrical wires from heater terminals. Label connections before removal.
• Measure heater element resistance with multimeter: expected reading 10-30Ω. Infinite resistance confirms open element.
• Inspect all wiring connections for signs of arcing, melted insulation, or loose terminals. Tighten connections to 8 in-lbs torque.
• Replace faulty heater assembly using OEM part DC97-15010A: remove mounting hardware, extract old unit, clean chamber thoroughly, install new assembly with new gasket, secure mounting screws evenly.
• Test thermal cutoff fuse mounted on heater housing for continuity. Replace if open circuit.
• Reconnect wiring harness. Reassemble panels. Restore power and run diagnostic heat cycle while verifying exhaust temperature stabilizes within normal range (135-155°F).

Problem: Alternate representation of exhaust thermistor fault; identical failure mode to tE code

How to Fix Dryer Error

• UNPLUG dryer from electrical power source.
• Remove rear service panel to expose blower assembly and sensor locations.
• Identify exhaust thermistor mounted on blower housing adjacent to exhaust duct. Disconnect electrical connector.
• Using multimeter in resistance mode, measure thermistor value at room temperature. Reference service manual specifications (typically ~10kΩ at 77°F).
• If measurement shows open circuit, short circuit, or significant deviation from specifications, proceed with replacement.
