How to handle HACCP if the F410SS temperature is too high?

Handle this as a food safety event first, then a refrigeration issue:

Start an incident record immediately: note date/time discovered, the highest observed temperature, and whether the controller showed alarms or dEF.

Verify with a calibrated probe: record independent product temperature (not just air temperature). If you can, check the warmest point in the load.

Protect product: keep the door closed as much as possible. If you have alternative frozen storage, move at-risk product quickly (minimise time out of temperature control during transfers).

Assess and segregate: identify any high-risk items (e.g., ready-to-eat, high value, allergen-sensitive batches). Quarantine anything you are unsure about until a responsible manager reviews.

Document corrective actions: what you did (reduced loading, moved stock, cleaned condenser, called support), and what you will do to prevent recurrence (maintenance schedule, loading SOP, siting improvements).

If the freezer has been above your site’s safe limits for an unknown period, escalate to your HACCP lead and follow your company discard policy. Support can help troubleshoot the equipment, but do not wait for an engineer before making food safety decisions.
