Possible Causes

Failed defrost control component on PCB, Shorted defrost heater drawing excessive current, Wiring short in defrost circuit

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator. The defrost circuit is at mains voltage.

Step 1 – Inspect defrost heater and wiring:

  • Access the evaporator and defrost heater as described for E4.
  • Look for melted insulation or signs of arcing.

Step 2 – Measure heater resistance:

  • Disconnect the heater and check resistance; compare to specifications.
  • A very low resistance (near short) may indicate a partially shorted heater.

Step 3 – Replace suspect components:

  • If the heater or wiring is damaged, replace or repair before addressing the control board.
  • If the heater circuit is normal but E15 persists, the defrost control element on the main PCB is likely faulty.
  • Replace the main control board following standard safety and labeling procedures.
