Ice maker stops shortly after startup and displays E1 on the control panel.

Safety first: Unplug the Pro Breeze ice maker from the wall outlet before opening any panels. Never work on the unit while it is connected to power.

• Step 1 – Power reset: Unplug the unit for 10 minutes, then plug it back in and restart. If E1 returns, continue.
• Step 2 – Check installation environment: Ensure the ice maker is in a room between 10–32°C (50–90°F). Extreme temperatures can trigger sensor errors.
• Step 3 – Access the sensor: Remove the rear or side service panel (typically held by Phillips screws). Locate the small NTC sensor clipped near the air intake or condenser area, connected by two thin wires to the main PCB.
• Step 4 – Inspect wiring and connector: Check for loose plugs, corrosion, or damaged insulation. Reseat the connector firmly on the main control board.
• Step 5 – Test the sensor (if you have a multimeter): Disconnect the sensor and measure resistance. At room temperature (around 25°C / 77°F), most NTC sensors should read between 5–20 kΩ. If it reads open (OL) or 0 Ω, the sensor is defective.
• Step 6 – Replace the sensor: If faulty, order a compatible Pro Breeze ambient temperature sensor (NTC). Clip the new sensor in the same location, route the wires away from hot or moving parts, and reconnect to the PCB.
• Step 7 – Reassemble and test: Refit the panel, plug in the unit, and run a full ice cycle to confirm the E1 code is cleared.

If E1 persists with a known-good sensor, the main control board may be defective and should be replaced by a qualified technician.
