Safety first: Disconnect power before testing sensors or removing panels.

Steps to resolve LO:

Identify which zone: On dual-zone Hoover wine coolers, LO may apply to upper or lower zone. Check which display is affected.
Access the relevant sensor: For the affected zone, locate the cabinet NTC sensor (see E1). Remove any cover or grille if necessary.
Inspect for moisture: Condensation or a water leak can cause the sensor to short. Dry the area thoroughly and ensure the drain is not blocked.
Test sensor resistance: Disconnect the sensor and measure resistance at room temperature. A very low resistance (near 0 Ω) indicates a shorted sensor.
Check wiring: Look for points where the two sensor wires may be touching due to damaged insulation.
Replace sensor: Install a new Hoover-compatible NTC sensor if the old one is shorted or water-damaged. Route the cable to avoid future moisture exposure.
Re-test: Restore power and verify that the temperature reading is realistic and that LO has cleared.

Display shows LO or a very low temperature reading that does not change, even when the interior is warm.
