The short answer
When a Maytag cooktop displays F13, the control is naming the communication link. What the manufacturer documents is in the table; what to check first is in the ranking under it. If a restart brings it back and a cycle completes, it is usable meanwhile.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| F13 | There is an internal communication error on the touch control module . |
What you actually observe
- Settings can be entered but no cycle ever starts — The command is accepted and never arrives.
- The fault comes and goes with no pattern you can see — An intermittent link is a wiring symptom far more often than a board symptom.
- The panel lights, then goes dark again a moment later — That sequence says one board woke up and lost its partner.
- NEAR MISS — one specific key does nothing and the rest work — That is an interface fault, not a lost link.
Causes, most likely first on this cooktop
- A connector only part seated at one end of the link — Both ends look perfect from the front; a plug one pin out of alignment still reports as a lost link.
- A broken conductor inside the harness that joins the two boards — Flexing where the harness crosses a hinge or a panel edge breaks a single strand at a time, which is why the fault comes and goes first.
- One of the two boards no longer answering — The code describes the conversation, not the speaker, so either board can be the one that fell silent.
- A supply fault that leaves one board unpowered — If the far board has no supply it cannot answer, and the near board reports the silence as a lost link.
Check in this order, and why
- Power down fully and restart before opening anything — A link restored by a cold start was interrupted rather than broken.
- Note whether the display lights at all — A dark panel and a lit panel that reports the fault point at different halves of the link.
- Get both connectors reseated before condemning either board — Reseating both connectors is the fix in a large share of these calls and costs nothing in parts.
- Replace boards one at a time, never as a pair — Changing both hides which one was at fault and doubles the bill.
What an owner can safely check
- Take the power off at the breaker for at least a minute — Both boards must lose their standby supply together; switching the appliance off at its own control does not do that.
About 3 min
- Restore power and watch the first seconds of start-up — Whether the panel lights before the code appears tells a technician which end woke up.
About 3 min
- Write down what the panel shows at each stage — A short sequence of observations is worth more than a general description on the phone.

Before anything is opened
Safety
Take the power away first: unplug the appliance or switch off its breaker before removing any panel, since a capacitor can hold a charge after the power is off. A cooktop is hard-wired in most installations, so the breaker is the only isolation point — there is no plug to pull. The glass also holds heat long after the elements read as off. Nothing on the door circuit should be re-routed or held closed. It interrupts power by design.
When this stops being an owner job
Book the visit as soon as a cold start has failed to restore the link. After that the next move is behind a panel, and nothing under the glass can be reached until the unit is lifted out of its cutout. Whatever the timing above, a burning smell, visible scorching or a tripping breaker means the appliance goes off at the breaker and the call goes in today.

What this page does not cover
This is the platform-level reading of F13: it holds for the Maytag cooktop families that share that control generation. It does not cover older generations that reuse the same characters for something else, and it deliberately carries no wiring colours, no connector pin numbers, no torque figures and no part numbers, because every one of those differs by family. Where a page exists for your specific family or model, that page is the more specific answer and it is the one to follow; the code index linked below is where those pages are listed.
