Move any food or containers pressing against the light cover at the top of the fresh food section. If it comes back, it needs a visit. ### Could something in my fridge cause Sub-Zero 35 R 33? It can. On Classic units the fresh food evaporator fan sits behind the light cover at the top, and food pressed against that cover can slow it. Move anything touching the cover before trying a breaker reset. ### What if 35 R 33 returns after I cleared the light cover? Then the fan is still running slower than the board expects for some other reason, and a service visit is next. Note that this is the refrigerator fan; the freezer fan has its own code, 35 F 33. --- **[Read on the site: Sub-Zero refrigerator showing 35 R 33](https://refrigeratorrepair.center/error-codes/sub-zero-35-r-33/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
