Error codeF4E6
ApplianceWall Oven
What F4E6 points to
Whirlpool wall ovens display F4E6 when the control sees a possible fault with the microwave wave guide temperature sensor or the associated wiring. The entry is filed under wall ovens.
Whirlpool’s reset, step by step
Shut the oven’s breaker off.
Wait one (1) minute before turning it on.
Keep an eye on the oven for one (1) minute afterward.
Check that normal operation has returned.
When the reset does not hold
Seeing F4E6 a second time means a technician visit is the next move; the product help offers nothing further for the owner to do.
Anyone in San Francisco or the wider Bay Area with a Whirlpool wall oven showing F4E6 can arrange a technician visit at (415) 687-4102. Share the model number and how the reset went. Our Whirlpool wall oven repair page has the background.
Model compatibility: Whirlpool reuses codes across series and model years, so F4E6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F4E6 means the microwave wave guide temperature sensor or its wiring may be faulty.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
