By Marcus Reed · Lead Sub-Zero Technician · 20+ yrs · Oakland & East Bay A noisy Sub-Zero in Oakland is usually a failing evaporator or condenser fan motor, ice buildup hitting a fan, or a dirty condenser making the compressor work harder. Persistent loud running can also signal a sealed-system strain. We locate the source and quote before any work.
Fan and ice noise
Buzzing/whirring often traces to a fan motor or frost contacting a fan blade. A clean condenser and a fan check resolve most noise complaints.
Constant loud running
If it runs loudly all the time, see code 50 (excessive run time) — often a dirty condenser, gasket or defrost issue.
