Easy to reach, fast response
I called about a warming Sub-Zero and got a clear plan, not a sales pitch. He measured the fresh-food side, found the fan, and documented the fix.

Urgency
What to do if temperatures are rising now
Food safety comes first.
- Move perishable food to backup cooling if temperatures are unsafe.
- Photograph the display and write down temperatures before resetting.
- Mention whether the freezer still holds or both compartments are warm.
- Do not remove panels, cut gaskets or force the unit out.
- Preserve alarm and temperature evidence when it is safe to do so.
Area map
Castro Valley service context
The service-area outline and notes clarify how each neighborhood affects routing and prep.
Central Castro Valley and Green Ridge calls benefit from model-tag photos because many kitchens include older built-ins.
Five Canyons and Palomares Hills appointments often need cabinet and floor-protection planning.
San Leandro, Hayward and San Lorenzo may be grouped when the symptom is stable and parts are confirmed.
