the power button light is on but nothing happens, no noise, no ice, just sits there

Diagnosis

The hOmeLabs HME010019N is designed with a specific logic sequence that prevents the compressor from engaging immediately upon plugging the unit in. When the power light is illuminated but the machine remains silent, the unit is in a "Ready/Standby" state. In this mode, the internal control board has power, but the cooling cycle is dormant because the user has not yet specified the desired ice volume. This behavior is often mistaken for a dead compressor or a blown fuse, but it is actually a safety and preference feature. The machine will not initiate the refrigeration process—which involves the fan starting and the compressor kicking in—until a specific cube size (Small or Large) is selected. You can confirm this is the issue if the power light is steady and there are no flashing "Add Water" or "Ice Full" indicators on the LED panel.

How to Fix It

To move the unit from standby mode into an active ice-making cycle, follow these exact steps:

1. Ensure the water reservoir is filled to at least the halfway mark; if the water level is too low, the sensor may block the cycle from starting even after selection.
2. Locate the 'Select' button on the top control panel.
3. Press the 'Select' button once. Observe the LED indicator lights. You should see the light shift to either the 'Small' or 'Large' cube icon.
4. Wait approximately 5 to 15 seconds. You should first hear the internal cooling fan spin up, followed by a distinct "click" and a low hum as the compressor engages.
5. If the lights change but you hear no mechanical movement, press the 'Select' button again to toggle to the opposite size. This forces the control board to re-send the start signal to the compressor relay.

If That Didn't Work

• Perform a Hard Power Cycle: Unplug the power cord from the wall outlet entirely. While unplugged, press and hold the power button for 10 seconds to discharge any remaining electricity in the capacitors. Leave the unit unplugged for a full 5 minutes to allow the refrigerant pressures to equalize. Plug it back in and attempt the 'Select' sequence again.
• Check the Ice Basket Sensor: The HME010019N has infrared sensors that detect when the ice basket is full. If the basket is slightly misaligned or if there is a piece of stray ice blocking the sensor lens, the machine will think it is full and refuse to start the motor. Remove the basket completely, wipe the sensor lenses (small clear windows) with a dry microfiber cloth, and re-seat the basket firmly.
• Verify Ambient Temperature: If the machine is in a room that is too cold (below 60°F / 15°C) or too hot (above 90°F / 32°C), the internal thermal protector may prevent the compressor from starting to avoid overheating or freezing the lines. Move the unit to a room with a stable temperature of 70°F and try again.
• Inspect for Air Locks: If the unit has been tilted during transport, an air bubble may be trapped in the pump line. Gently tilt the machine 15 degrees in various directions while it is powered on to help the pump prime itself, then press the 'Select' button again.

Heads Up

• Clearance Requirements: Always maintain at least 6 inches of open space on all sides of the unit. If the vents are blocked, the machine will overheat and the compressor will shut down automatically without turning off the power light.
• Water Quality: Use filtered water whenever possible. Mineral buildup from hard water can clog the internal spray nozzles, causing the machine to run but fail to produce ice, or trigger a sensor error.
• First-Run Patience: The first batch of ice often takes longer than subsequent batches. Allow the internal evaporator plate to reach the target temperature for 10-15 minutes before assuming the unit is malfunctioning.
• Avoid Frequent Toggling: Do not press the 'Select' button rapidly. The compressor requires a "dwell time" to protect the motor from pressure spikes; rapid switching can trigger a temporary lockout.
