The short answer
F13 reports an internal communication error on the touch control module — the same class of fault as its neighbours in this family, and the same single owner action: one power cycle at the breaker. What you can usefully add is observation. How long the code stays away after a reset is the most valuable thing you can hand a technician, and it costs nothing but a note.
Whirlpool cooktop code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| F13 | 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 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.
- A failed touch control module — Fourth: the module is an electronic assembly living under a hot glass panel, and it does eventually fail outright.
- 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 chafed or pinched ribbon between module and control — Second: the loom is routed close to the glass and to the frame, and installation damage shows up months later.
Check in this order, and why
- Write down the date each time the code appears — A shrinking gap between appearances is a connector; a steady gap is not.
- 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 F13 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.
