Display shows Lo and the cooler will not allow setting a lower temperature or appears locked.

Safety: This is typically a control setting, not an electrical hazard. No need to unplug unless removing panels.

Steps:

• 1. Check user manual: Many Kalamera models use a key combination (such as holding the up and down arrows together for several seconds) to toggle child lock or temperature lock. Try the documented sequence.
• 2. Attempt unlock: Press and hold the lock icon or both temperature buttons simultaneously for 3–5 seconds until the lock indicator turns off or the display changes.
• 3. Power reset: If the panel does not respond, unplug the unit for 5 minutes, then plug it back in and try the unlock sequence again.
• 4. Inspect keypad: If certain buttons appear stuck or unresponsive, the keypad may be faulty. Remove the control panel and inspect for physical damage or moisture.
• 5. Replace control panel if needed: Install a new front control panel assembly if the lock cannot be cleared due to keypad failure.
