A vent that is covered by a griddle or a cutting board
What separates it Something stored on the range top blocks the slots
How to confirm Remove it and run a short bake
- 4
A dying motor
What separates it A grinding or squealing note
How to confirm The fan is replaced

Before you touch a setting
Record this first — changing settings destroys the evidence
- That the glass control shows the words Cooling Fan Speed
- Whether a convection fan or a warming drawer was in use
- What the fan sounded like
- The model number from the frame behind the oven door

Reversiblelet the control cool and lift anything stored on the range top.
Correct only the documented fault domain
ReversibleCycle the breaker, bake at a moderate setting and listen near the control; book service for a fan that is slow, noisy or silent. A power reset is the whole of what JennAir publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Switch the range off for an hour
ReversibleLet the glass control and the cabinet cool, and leave the door ajar.
Clear anything stored on the range
ReversibleRemove cutting boards, griddles and trays from the top and look at the slots near the control.
Bake and listen
ReversibleBake at a moderate temperature and listen for the control cooling fan about ten minutes in. It is separate from the convection fan, which has a different sound and its own codes.
Reset the power
ReversibleSwitch off at the breaker for a minute and on again.
Describe the sound
ReversibleA steady whoosh, a rattle, a squeal or silence each point to a different fault.
Call JennAir service
ReversibleIf the message returns, a technician measures the fan speed and replaces the fan or its sensor.
Model-specific
What is true of this model and not of its siblings
- A pro-style range runs hotter
- JennAir pro-style ranges have heavy-duty burners and a large oven, which put more heat into the cabinet than a basic range. The cooling fan has more work to do, and a fan that was adequate when new can struggle once dust and grease have coated it.
- Keep the range top clear
- Large griddles and pans left on the range top block the vents that feed the cooling fan. Using the warming drawer and the oven together for a dinner party is when the message tends to appear, so lift the boards and trays before a long cook.
Stop boundary
When this stops being a self-service repair
- !Ask JennAir service to bring the cooling fan and its sensor, since a premium range deserves a proper repair
- !Do not self-clean until it has been checked
- !Switch the range off at its breaker before the back is opened

Common questions
What does Cooling Fan Speed mean on a JennAir range?+
the cooling fan for the glass control is not holding its expected speed
Is it the convection fan?+
No, the convection fan moves hot air in the cavity, and this fan cools the control.
Is a premium range worth repairing?+
Usually yes, since a fan is a modest part on an expensive appliance.
Can I use the cooktop?+
Yes, for a short while, though the same fan cools the control.
Why does it only appear after a long bake?+
The fan is checked when the cabinet is hot.
