What this usually means
Ice building on the evaporator, floor or door of a freezer means the defrost is not keeping up or moisture is entering the box.. Several causes can produce the same symptom, which is why diagnosis matters more than guessing.
Likely causes
- Defrost heater failure. A dead heater lets frost accumulate every cycle.
- Defrost termination or timer fault. The cycle may end early or never start.
- Door gasket leaks. Moisture freezes on the first cold surface it meets.
- Frozen drain line. Melt water refreezes on the floor.
- Heavy door traffic. Frequent openings add humidity faster than the system can remove it.
Safe checks you can do first
- Look at the door gasket along its full length
- Check the floor for ice near the evaporator
- Note when ice appears relative to deliveries
What not to do
- Do not hammer ice off the coil
- Do not prop the door open during unloading
How a technician finds the cause
We start with airflow and the condenser, move to the electrical components, and only then gauge the sealed system. That order finds the real fault faster and keeps the repair proportionate. A service call is $135 for a new customer's first visit and $185 for a standard visit. Repair labor, parts, refrigerant and materials are quoted after diagnosis, and you approve the price before any work begins.
When to call
Persistent ice despite good door habits points to a defrost fault that needs testing. Availability varies by location, equipment, brand and technician schedule; listing a city does not guarantee same-day arrival. Call to confirm service for your address.
