How to Fix / Troubleshooting
Safety first: Do not attempt to cut or open refrigerant lines yourself.
Steps to evaluate partial frost pattern:
- Observe frost: After 10–20 minutes of run time, inspect the evaporator. If only a small section frosts while the rest remains bare, a sealed system issue is likely.
- Check fans and defrost: Confirm the evaporator fan runs and defrost system is not stuck on. If these are normal, the problem is within the sealed system.
- Professional service: Contact a licensed refrigeration technician to check for leaks, measure pressures, and repair or recharge the system.
Note: Sealed system repairs can be costly; consider the age and value of the freezer before proceeding.
