• What does the 'PF' code mean on my Foster display?

  The 'PF' code stands for Power Failure. It indicates that the mains power to the appliance was interrupted and has now been restored. On many models, you can typically cancel this alarm by pressing button 1 on the controller.

• How do I manually defrost my Foster freezer?

  Most Foster units defrost automatically. However, to initiate a manual defrost, press and hold the appropriate button (often button 1) for 5 seconds. The display will briefly show 'dEF' to indicate the cycle has commenced.

• What should I do if the 'hi' or 'Lo' alarm appears?

  'hi' indicates the internal temperature is higher than the set limit, while 'Lo' means it is too low. Check for door obstructions, airflow blockages, or incorrect loading. If the issue persists, contact Foster service.

• How do I lock the keypad on my Foster controller?

  To prevent unauthorized adjustments, you can lock the keypad. On standard controllers, press and hold button 2 for 3 seconds until 'SP' appears, release, and press button 2 again until 'Loc' shows. Use the arrow keys to select 'Yes' and press button 1 to save.
