The short answer
F03 is published as an internal communication error on the touch control module. That is a fault inside the assembly behind the glass, not something in your kitchen, so there is exactly one owner-level action: cut the power at the breaker for a minute and restore it. If it clears and stays clear, it was transient. If it returns, the module or its wiring needs a technician.
Whirlpool cooktop code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| F03 | There is an internal communication error on the touch control module . |
What you observe alongside the code
- The code with the cooktop cold and nothing cooking — A communication fault does not need heat to appear.
- Controls dead or partly responsive — Some keys answer, some do not.
- It clears on a power cycle and returns later — The signature of a connector rather than a dead module.
- It follows a storm or a breaker trip — Points at a supply disturbance that latched the fault.
What triggers it, most likely first
- A supply disturbance that latched the fault — Last: a brownout or a spike can leave the link out of step until the cooktop is power-cycled.
- A loose or partly seated connector at the touch module — First: it is a fine-pitch connector in a cabinet that gets hot and cold twice a day, and thermal cycling walks it out.
- Moisture ingress at the module — Third: steam finds its way under the glass edge, and damp on a data connection reads as a corrupted link.
- A failed touch control module — Fourth: the module is an electronic assembly living under a hot glass panel, and it does eventually fail outright.
Check in this order, and why
- Power the cooktop down at the breaker for a full minute, then restore — The only owner-level action this code supports.
- Power the cooktop down at the breaker for a full minute — A fault that clears and stays away for weeks was a transient.
- Note whether the code sets from cold and idle — A code with no heat and no cooking rules out the thermal causes.
- Count how long it stays away after each reset — A shrinking interval is a connector or a module on the way out.
Clearing the code, then the owner-safe checks
- Switch off at the breaker for a full minute, then restore — The documented first response, and it clears the latched state.
About 5 min
- Wipe the control area and the glass edge dry — Removes the surface moisture that can bridge into the module.
Tools: clothAbout 10 min
- Record the date each time the code appears — Two or three dated appearances turn guesswork into a pattern.
About 10 min
- STOP HERE — do not lift the glass to reach the module — The glass is bonded to the frame and the module sits directly beneath it.
Before you open anything
Safety
Switch the cooktop off at its breaker before any panel comes off — a capacitor can hold a charge after the power is off, and a cooktop is fed from a double-pole breaker, so both poles have to be dead. The glass stays hot long after the zones are off. Never bridge or bypass a thermal cut-out or an interlock to keep cooking. A cooktop whose controls are unreliable should be left off at the breaker rather than trusted to switch off at the panel.
When this code is a service call
Call when a power cycle no longer holds, or when the interval between appearances is shrinking: the connector, the ribbon and the module all sit under bonded glass and none of them is an owner repair. Call immediately if a zone stays hot after the controls are switched off, and use the breaker to kill it in the meantime.

Which model lines this reading applies to
This reading of F03 applies to Whirlpool induction and radiant glass cooktops with the touch control that publishes this code, which is where the manufacturer documents it. A knob-controlled coil or gas cooktop has no display and cannot produce it, and a Whirlpool-built unit badged for another brand may pair the same characters with a different fault. Touch control modules differ between radiant and induction families and are not interchangeable between them.
