The answer up front
4d41 on an oven of this generation means the speed feedback from the cooling fan came back above its window. There is no protective shutdown behind this one, so the practical cost is noise and a code on the display. The first thing worth eliminating is a feedback signal the control misread rather than a fan that is genuinely racing.
The code table for this reading
Reference| Code | Documented meaning |
|---|---|
| 4d41 | Cooling fan speed too high. |
What is happening apart from the display
- The fan runs on long after the oven is cool — Running when it should have stopped is the same disagreement seen from the other end.
- The code appears with no change in how the oven cooks — Unlike its opposite, this one often has no cooking symptom at all.
- NEAR MISS - the fan is loud and the cavity is also too hot — Two symptoms at once points at the temperature side rather than the fan, and that is a different page.
What triggers this code, most likely first
- A misread speed signal rather than a fast fan — Ranked first because it is the commonest and the cheapest: the tacho feedback is noisy, the fan is fine, and a power-down clears the latched reading.
- The fan running unregulated at full speed — Second: a drive that has lost control of the motor leaves it at maximum, which is audible from the next room.
The cheapest checks first
- Listen for whether the fan is genuinely at full speed — If it sounds normal, the fault is the reading and not the fan.
- Note whether it runs on after the oven is cold — A fan that never stops is a drive fault; one that stops on time is a feedback fault.
The safe checks, step by step
- Power the appliance down at the breaker and bring it back — The documented first action, and it clears a latched misread.
About 5 min
- Run a short bake and listen to the fan through the cycle — Normal-sounding with no code is finished; loud with a code is a service call.
About 25 min
- STOP HERE - the fan and its wiring sit behind the appliance — Reaching them means pulling a built-in unit out of its opening.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off. Everything in the procedure above stays outside the cabinet for that reason. Leave the door switch and the other interlocks exactly as they were fitted - they exist to stop the appliance running when it should not.
When a reset is not the answer
Call if the code returns after a power-down or the fan will not stop when the oven is cold: an unregulated fan is a drive or a motor fault and both are service parts. There is no emergency in this code by itself. Call sooner if it arrives alongside an oven that will not hold temperature, because then the fan is not the subject.

How far this page applies
Applies to: the built-in model lines whose control monitors fan speed in both directions. Does not apply to: a specific model's wiring, its part numbers, or its service procedures, all of which vary and none of which are invented here. This page is the general reading of one code; where a more specific page exists for your family or model it is linked from the index below and it is the one to read first.
