F25 in brief
F25 means the cooktop has found a problem with the power reaching it: the supply is missing, low or unstable. Check the breaker before anything else, and do not keep cooking while the code returns, because a loose supply connection overheats under load.
Error codes
Reference| Code | Meaning |
|---|---|
| F25 | There is a problem with power supply to the cooktop. |
Signs that go with the code
- Zones heat weakly or switch off under load — The supply sags when power is drawn.
- The breaker has tripped, or one handle feels loose — A two-pole breaker that half-trips starves the cooktop.
- Lights dim when the cooktop is in use — A loose connection upstream.
- NEAR MISS: only one zone fails — That is a zone fault, not the supply.
Causes, most likely first
- Breaker partly tripped or worn — The most common cause: one half of the two-pole breaker opens, or a worn breaker no longer holds a firm connection.
- Loose connection at the junction box — Second: the cooktop is wired into a box under the counter, and a loose or burnt connection there starves it.
- Household supply problem — Third: a utility or panel issue that affects other heavy appliances too.
- Cooktop power input fault — Last: the cooktop’s own power board misreading a good supply.
The order to check, and why
- Reseat the breaker — Fully off, then firmly on.
- Watch other heavy appliances — If they misbehave too, the problem is upstream.
- Note the load when the code appears — One zone or several.
- Electrician checks the junction box — Then a technician checks the cooktop if the supply is good.
Owner steps, with tools and time
- Breaker reseat — Switch the cooktop’s breaker fully off for a minute, then firmly on.
Tools: flashlightAbout 3 min
- Single-zone test — Run one zone with a pan, then add a second, and note when the code appears.
Tools: pan of waterAbout 10 min
- House check — Run another heavy appliance and watch for dimming lights.
About 5 min
- STOP before opening the junction box — The supply connection under the counter is electrician work; leave the breaker off if anything smells hot.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The electronics under the glass run at high voltage and are not owner-serviceable; owner checks stay on top of the glass and at the breaker.
When this is a service call
Call an electrician when the breaker trips, the lights dim with the cooktop on, or anything smells hot under the counter; call an appliance technician when the supply checks out and the code remains. A loose high-current connection gets worse with every use.

Which models this reading covers
Generalized information for Amana electric and induction cooktops with touch controls. It is not a reading for 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. The details that change inside the line, such as wiring colours, part numbers and connector locations, belong on model pages, and none is published for F25 yet.
