Frost & Defrost

Heavy frost or ice building up in your Sub-Zero freezer usually means a failed defrost heater, sensor, or control, often an EC24 code. Same-day Seattle repair.

Loud Noise & Compressor

New humming, buzzing, or rattling from your Sub-Zero is usually a worn fan bearing, but a loud compressor buzz or knock with an EC40 code needs fast attention.
