What the cooktop is detecting
The user interface expects regular messages from each power board over the data bus. When appliance manager 1 stops responding, F6E6 is stored and its elements cannot be used.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A loose or damaged data-bus connector on that board.
- Documented A failed appliance manager 1 board.
Safe checks you can make
- Switch the cooktop off at the circuit breaker for about one minute, restore power, and see whether the code comes back.
- Write down the full code exactly as shown (including any number after a dash) and when it appears; it speeds up diagnosis.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the communication harness and connectors between the boards.
- Identifies which board stopped communicating before replacing it.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Cooktop control or induction board replacement | $300–$770 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The cooktop may not respond or may shut zones off. A power reset sometimes clears a one-time glitch; a code that returns points to a wiring or board problem that needs diagnosis.

Repair or replace?
A fault code alone rarely justifies replacing a cooktop. Most F6E6 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 13–17-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
