Heavy ice usually means moisture, airflow, defrost, drainage, control, or refrigeration performance is out of balance. Review practical checks. Published and updated August 26, 2026 Fort Worth Cold Care prepared this operator guide for commercial refrigeration decisions in the Fort Worth service area. Heavy ice usually means moisture, airflow, defrost, drainage, control, or refrigeration performance is out of balance. The frost pattern should be documented before controlled thawing because it helps separate the causes. This guide is written for Fort Worth commercial operators. It does not replace the equipment manufacturer, a licensed contractor, the person in charge, or current regulatory requirements. Preserve safety and product records before troubleshooting. ## Door infiltration adds moisture A torn gasket, failed closer, propped door, damaged threshold, or heavy traffic admits warm moist air that freezes on cold surfaces. ## Airflow problems change coil temperature Failed fans, blocked grilles, ice, dirty surfaces, or product stacked into the air path can reduce heat transfer and deepen icing. ## Defrost and drainage act together Timers, controllers, heaters, termination devices, fan delays, drains, and drain heat may need sequence testing. A thaw alone does not prove which part failed. ## Avoid damaging the evaporator Do not chip ice or use uncontrolled heat. Fins and tubing are fragile, electrical components may be exposed, and meltwater creates slip hazards. ## What to record before requesting service Photograph the data plate and visible condition without removing guarded panels or entering unsafe areas. Record current and target temperature or output, alarm text, the time the condition began, product exposure, recent loading or cleaning, actions already taken, and whether fans or the condensing unit appear to run. Add the business ZIP code, access instructions, service deadline, and authorized decision-maker. ## When the issue is urgent Escalate promptly when people may be unsafe, cold-held product is warming, a critical system has no redundancy, water is near electrical equipment, or a suspected refrigerant or electrical condition is present. Urgency does not authorize unsafe staff work. The responding provider must confirm coverage and timing. ## Bottom line Heavy ice usually means moisture, airflow, defrost, drainage, control, or refrigeration performance is out of balance. The frost pattern should be documented before controlled thawing because it helps separate the causes. Use the related service page to understand the first-visit scope, then send a complete service request through the contact page. ## Sources and basis Relevant official references include Texas DSHS food-establishment guidance , Texas ACR licensing information , EPA Section 608 refrigerant-management updates , and Fort Worth food-establishment plan review .

The frost pattern should be documented before controlled thawing because it helps separate the causes. Record equipment identity, temperature or output, alarm or symptom, timeline, operating conditions, actions taken, and access details. Request qualified help when temperature, product, safety, refrigerant, electrical work, controls, or system diagnosis is involved, or when safe staff checks do not resolve the condition. ## Continue the decision ### How Long Is Food Safe When a Cooler Fails?
