EdgeStar ice maker displays E13; the unit may not defrost properly, and ice may stick to the evaporator.

Safety first: Unplug the unit before accessing the compressor compartment. Sealed system repairs must be performed by a certified technician.

• Observe harvest cycle: During harvest, the unit should briefly warm the evaporator to release ice. If ice remains firmly stuck and E13 appears, the hot gas valve may not be opening.
• Check valve wiring: Locate the hot gas solenoid valve near the compressor. Verify that the electrical connector is secure and the wires are not damaged.
• Test coil resistance: With power disconnected, measure resistance across the valve coil. An open circuit indicates a failed coil.
• Replace the hot gas valve (coil only if possible): If the coil is removable, replace only the coil with an OEM EdgeStar part. If the entire valve body is defective or the line is blocked, a sealed system repair is required.
• Call a technician for sealed system work: If replacing the coil does not restore harvest function, contact a professional for hot gas valve or line replacement and system evacuation/recharge.
