Evaporator does not frost at all while compressor is running

Warning: Sealed system and compressor electrical work should be performed by qualified technicians.

• Basic checks: Confirm the condenser fan runs and that the compressor is warm to the touch after running.
• Listen for compressor: A loud click followed by silence may indicate a failed start relay or overload protector.
• Inspect start components: With power disconnected, remove the compressor start relay/overload and check for burnt odor or rattling pieces. Replace if defective.
• Call a technician: If the compressor runs but no frost forms, or if it will not start even with new start components, a sealed system diagnosis and repair is required.
