Haier Loc

Haier error code LOC indicates: Haier Series 4 / 6 Chef@Home & I-Message Connected Oven: Child safety lock active Loc; control panel keypad inputs are locked to prevent accidental burner/oven activation..

The primary root cause for Haier code LOC is: On Haier ovens utilizing Chef@Home multi-zone convection system, high-precision cavity thermal probe, and I-Message electronic controller: Key lock feature engaged by user holding the Keypad Lock or Clear/Off pad for 3 to 5 seconds..

To resolve error code LOC: Press and hold the Key Lock / Padlock icon pad continuously for 3 to 5 seconds until confirmation beep sounds and 'Loc' message disappears. Touch Settings menu on display, select System Reset, hold confirmation checkmark for 5 seconds, or power cycle breaker for 60 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code LOC persists, the physical component causing On Haier ovens utilizing Chef@Home multi-zone convection system, high-precision cavity thermal probe, and I-Message electronic controller: Key lock feature engaged by user holding the Keypad Lock or Clear/Off pad for 3 to 5 seconds. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
