Frost buildup on the evaporator coils or back wall of your freezer usually indicates a problem with the defrost system. When this system fails, airflow becomes restricted, causing uneven cooling and forcing the compressor to run continuously.
If left untreated, this issue can increase energy consumption and shorten the lifespan of your appliance.
What Causes Freezer Coil Frost Buildup?
The most common causes include:
- Faulty defrost heater
- Malfunctioning defrost thermostat
- Broken defrost timer
- Poor door sealing allowing moisture inside
These components regulate temperature and prevent ice accumulation. When one fails, frost forms rapidly and cooling performance drops.
Can I Fix Freezer Frost Myself?
In some cases, manually defrosting the freezer may provide temporary relief. However, if frost returns quickly, the issue likely requires professional diagnosis.
Homeowners in Baltimore often rely on expert refrigerator repair services to properly test electrical components and restore safe operation.
When Should I Call for Professional Repair?
