What F42, F43 or F58 Means
Maytag publishes F42, F43 and F58 with the same attribution on electric and induction cooktops: a possible problem with the cooktop power control board or the associated wiring. Because the documentation gives them one cause and one answer, they are recorded here as a single board-side fault rather than three thin entries.
Common Causes of F42, F43 or F58
- Transient board fault cleared by a reset
- Wiring connector loose or heat-damaged
- Power control board failed
- Supply problem stressing the board
🔧 One Safe Check You Can Try
Switch the cooktop off at the breaker for a minute and restore power, then test each zone in turn on a low setting. Note which zones work and which do not, and whether the panel itself behaves normally, because a board fault that affects only some zones is a different job from one that kills the whole cooktop. Beyond the reset, everything these codes name is under the glass.
⚠ Why You Shouldn't Go Further Than That
- The power control board sits beneath the glass on a high-current circuit.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
