COOL FAN appears when the apparency switch, a small switch that confirms the cooling fan is actually moving air, reports that the fan is not working. Wolf lists two causes: the fan itself, or the switch that watches it. Wolf range display What to do when COOL FAN shows on the range ### Kind of code Fans The convection fan behind the oven's back wall, or the cooling fan that keeps heat away from the controls, did not spin as fast as the control expected. Grease on the blade and a loose plug are checked first; a tired motor, and on the cooling side a thermal fuse, come after. ### Usually leads to Convection fan repair A convection oven on a range that bakes unevenly, rattles, squeals or never starts its fan, traced to the motor, the blade or the convection element. ### Shows up as Range Oven Not Heating The burners or elements on top work, but the oven below stays cold, heats only a little, or never finishes preheating. ### Make Wolf The cooking brand of the Wisconsin-based Sub-Zero Group, known for red-knobbed gas, dual-fuel and induction ranges. ### Source Wolf answer: legacy dual-fuel range, COOL FAN Legacy Wolf dual-fuel ranges. ## Before you book, in this order. Each step comes from Wolf's own guidance for COOL FAN on its ranges. Follow it to the end: the last card says whether this is a visit. 01 Turn the breaker off for about 30 seconds, then back on, and run the oven again. 02 If COOL FAN returns, stop using the oven, since the cooling fan protects the controls from oven heat, and book a visit. ### Still there?

Turn the breaker off for about 30 seconds, then back on, and run the oven again. If it comes back, it needs a visit. ### My Wolf range shows COOL FAN but I can hear a fan. What is going on? Wolf allows for that case: the message can come from the switch that watches the fan as well as from the fan. A running fan with a bad apparency switch still sets COOL FAN, and a technician can tell which of the two is to blame. ### Is COOL FAN on a Wolf the same as the convection fan not working? No. COOL FAN is about the fan that keeps the range's electronics cool. A convection fan problem shows up as uneven baking rather than as this message. --- **[Read on the site: Wolf legacy dual-fuel range showing COOL FAN](https://rangerepair.center/error-codes/wolf-df-cool-fan/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
