What F25 Means
Electric (radiant smoothtop) Cooktop, and on the page KitchenAid publishes jointly for Electric and Induction Cooktops: both carry the same two lines - there is a problem with power supply to the cooktop, and if the issue reoccurs, contact a qualified electrician. That second line is unusual on these pages and it is the important one. KitchenAid is saying that what this code reports may not be inside the appliance at all: it is about the electricity arriving at it. A cooktop runs on a dedicated high-current circuit, and a loose connection, a failing breaker or a lost leg of the supply produces exactly the sort of reading that makes a control stop.
Common Causes of F25
- A problem with the electrical supply reaching the cooktop
- A loose or degraded connection at the breaker, the junction or the cooktop terminal block
- A supply that is dropping or losing a leg under the load the cooktop draws
🔧 One Safe Check You Can Try
Switch every cooking area off and power the cooktop down by switching off its circuit breakers for one minute, power it back up, then watch the panel for one minute to be sure the code does not come back and verify the cooktop operates. Beyond that, the published instruction is not a repair step but a referral: if the code reoccurs, KitchenAid says to contact a qualified electrician. Note anything else in the house that has behaved oddly - lights dimming, other appliances on the same circuit stopping, a breaker that has tripped before - because that history belongs with the electrician rather than with the appliance technician.
⚠ Why You Shouldn't Go Further Than That
- KitchenAid itself sends this one to a qualified electrician, which is as clear a signal as its pages give that the fault may be in the circuit rather than the appliance.
- A cooktop circuit carries enough current to start a fire at a poor connection, and a loose terminal generates heat quietly inside a box nobody opens.
- Testing a supply means working at a live panel with instruments, which is exactly the work an electrician is licensed and equipped for and an owner is not.
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.
