What Cooling Fan Speed means

On JennAir electric, gas and dual-fuel ranges, for example the JES1750FS or JDS1750ML, the words Cooling Fan Speed on the display mean the fan is running too low or too high. An airflow restriction, the oven cooling fan or the wiring may be the cause. This text version covers the same ground as the numeric 4d2 and 4d4 codes. It appears on the display in place of the clock.

Common causes of Cooling Fan Speed

  • Airflow restriction around the range
  • The oven cooling fan is out of its normal speed range
  • Loose or damaged fan wiring
✓ One safe check you can try

1. Let the range cool. 2. Check that vents are open and nothing is stacked against the range. 3. Press Cancel. 4. Turn the breaker off for a minute, then on. 5. If the Cooling Fan Speed message returns, stop using the oven and call us. Mention whether the fan sounded slow or loud.

! Why to stop there
  • The message does not say whether the fan is slow or fast, so it needs a measurement.
  • A fan problem can lead to a hot control area.
  • Panel removal is a job for a technician.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Cooling Fan SpeedCooling Fan Speed questions
Does the message mean the fan is broken?

Not always. The fan speed is outside the expected range, which may be caused by airflow, the fan or the wiring. We test each before replacing anything.

Is this the same as 4d21 or 4d41?

It covers both directions in one message: speed too low or too high. The numeric codes tell you which one, and the text version leaves it to the technician.

Can you fix it the same day?

We aim to, depending on the schedule and part availability. You get a written price before we begin, and a 30-day workmanship warranty afterward on the repair.
