The answer first
On a Whirlpool oven, F8 E3 is about airflow. The control did not get the cooling-fan behaviour it expected from the oven cooling fan, and it names the wiring to it in the same line.

| F8 E3 | There may be a problem with the Oven Cooling Fan, or the associated wiring. |
What you observe
- The code appears part-way through a hot cycle and the oven shuts the heat off — The control allows the condition for a while, then stops. That is why the code so often lands in the middle of a roast rather than at switch-on.
- The fan is audibly wrong, or audibly absent — A bearing on the way out drones or rattles, a blade fouling its housing ticks, and a dead motor leaves a silence where the noise used to be.
- NEAR MISS — the fan runs constantly, long after the oven is off — A run-on fan is designed behaviour, not this fault. It carries residual heat away after the cycle.
Ranked causes
- The fan motor or its bearing is failing — Ranked first because it is the part the code names and the part that does mechanical work in the hottest air in the appliance.
- A connector or the harness to the fan is open or intermittent — The feed to a fan sits in the hottest part of the appliance, so insulation hardens and terminals oxidise there faster than anywhere else.
- The control that drives or monitors the fan has failed — Last: it is the least likely and the most expensive, and it is only worth considering once the airway is clear, the motor turns freely and the circuit reads correctly.
What to check first, and why
- Check the airway first, because it is free and it is common — Look at the vent the oven exhausts through, usually above the door or under the control panel, and at the intake beneath or behind the appliance.
- Listen through a full run with the room quiet — Note whether the fan starts, whether it changes speed, and when the noise changes.
- Measure the feed and the feedback at the control connector — This separates a fan that was never told to run from one that was told and could not.
The steps you can do yourself
- Cut power at the breaker for a full minute, then restore it — It clears the stored code so you can see whether the fault returns on the next run, and on airflow codes it also lets an over-temperature condition fall back to normal before you test again.
About 5 min
- Clear the vent and the intake, and check the clearances around the appliance — Vacuum the vent slots and the intake, take anything stored against the back or under the appliance out, and check nothing has been fitted across the vent since the oven went in.
Tools: vacuum, soft brushAbout 30 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is the line between an owner check and a service call on this circuit.
Before any panel comes off
Safety
Unplug the oven or switch off its breaker before any panel comes off. A capacitor can hold a charge after the power is off, and a built-in oven is normally hard-wired, so the breaker is its only disconnect. If your range burns gas and you smell gas: leave the building without switching anything on or off, call the gas utility or emergency services from outside, and do not look for the leak yourself.
Where the owner checks end
Call once the airway is clear and the code still appears, or immediately if the fan makes no sound at all during a run.

What this page does and does not cover
This page reads F8 E3 as Whirlpool documents it for ovens in this range, so it covers the appliance class rather than one model line: a wall oven, a range and a microwave-oven combination can all post it with different hardware behind the panel. Where a family- or model-specific page exists for your unit it is the more specific answer, and it is linked from the code index below.
