What F43 means
F43 names the power control board or its wiring. The keys may still respond, but heat depends on that board, so a code that survives a breaker reset is a service call.
Error codes
Reference| Code | Meaning |
|---|---|
| F43 | There may be a problem with the Cooktop Power Control Board, or the associated wiring. |
What you observe
- Zones heat weakly or cut in and out — A board or connection failing under load.
- A hot or burnt smell from under the cooktop — Overheating components or connectors.
- A click or buzz from under the glass when a zone starts — The board trying to switch.
- NEAR MISS: keys do not respond at all — That points at the touch side rather than the power board.
What usually sets this code
- Power control board failed — Most likely: the power board, which works hardest and hottest of anything under the glass.
- Burnt or loose high-current connection — Second: terminals and connectors on the power side loosen, heat and char.
- Heat from blocked ventilation — Third: trapped heat under the cooktop shortening the board’s life.
- Supply problem — Least likely: a weak or unstable supply that the board reports.
Check in this order
- Smell and listen — Burning smells or crackling mean the breaker stays off.
- Test zones one by one — Whether one, several or all fail guides the technician.
- Check the space beneath — Ventilation affects board life.
- Technician tests the board — Live-voltage work under the glass.
Clearing the code, then checking
- Zone survey — Switch each zone on briefly with a pan and note which ones heat.
Tools: pan of waterAbout 10 min
- Clear the underside — Make sure nothing below presses on the cooktop or blocks its vents.
About 10 min
- Note the trigger — Record whether the code comes at start-up or after cooking for a while.
Tools: notepad or phoneAbout 2 min
- STOP before testing anything with a meter — Live-voltage checks and part tests are where the owner side of this code ends.
Safety for this cooktop
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a cooktop that usually means the breaker, because the unit is wired into a junction box under the counter. Do not use a cooktop with cracked glass.
When to call a technician
Book a technician once a reset fails to clear it, and switch off the breaker if anything smells hot. The power board and its connections are the high-current heart of the cooktop, reached only from below.

Scope of this reading
The reading above covers Amana electric and induction cooktops with touch controls. It does not cover Amana gas cooktops, Amana ranges, whose surface codes are listed with the oven codes, or sister brands on the same platform, whose lists can read differently. A model-specific page for F43, where one exists, is the more specific answer; none exists yet, so check the use-and-care guide for your exact model before ordering any part.
