What this usually means
Without evaporator airflow, cold stays on the coil and the box warms; frost builds on the coil quickly.. Several causes can produce the same symptom, which is why diagnosis matters more than guessing.
Likely causes
- Failed fan motor. Bearings or windings fail.
- Blade damage. Blades crack or loosen.
- Electrical fault. A relay or wiring fault stops the fan.
- Frost jam. Ice jams the blade.
- Control or defrost logic fault. The fan may be held off.
Safe checks you can do first
- Listen for fan noise
- Look for a frosted coil
- Check for ice jamming the blade
What not to do
- Do not reach into the fan housing
- Do not run the system for long without the fan
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
A silent evaporator fan should be repaired promptly. 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.
