The Black Hammer

Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.

1) Call an emergency refrigeration technician immediately. 2) Take and document temperature readings. 3) Move the most temperature-sensitive items (proteins, dairy) to alternate refrigeration first. 4) Contact your health department if temperatures approach 40°F+ — they can advise on food safety decisions. 5) Document all food temps for insurance claims. 6) Consider dry ice or portable refrigeration units for critical inventory. 7) Alert your supplier you may need emergency replacement products.

Consider replacement when: repair costs exceed 50% of replacement cost, the equipment is over 75% of its expected lifespan, parts are no longer available, the equipment frequently breaks down, or energy costs are significantly higher than modern alternatives. Repair when: the equipment is relatively new, the repair is straightforward, and the total repair cost is well below replacement value. A qualified technician can help evaluate your specific situation.
