What F22 Means
Electric (radiant smoothtop) Cooktop: the published sentence for F22 is that there is an internal communication error on the touch control module, with a one-minute breaker reset as the procedure. It is the same sentence KitchenAid attaches to several other numbers on this family, and the practical consequence of that is worth stating plainly: the sentence describes a category, the number identifies the specific check that failed inside it, and only the number is worth quoting exactly when you ask for help.
Common Causes of F22
- An internal exchange in the touch control module failing to complete
- A signal from a contaminated or damaged touch surface the module cannot accept
- A module or connection affected by heat cycling under the glass
🔧 One Safe Check You Can Try
Let the glass cool first. A radiant or induction surface stays hot enough to burn well after the heat is off, which is why these cooktops carry a residual-heat indicator at all. With all controls off, 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. If it returns, check the obvious external thing before assuming electronics: whether the control area of the glass is clean, dry and clear of anything resting on it, since a contaminated panel can send the module signals it has to reject and the result looks like an internal problem from the outside.
⚠ Why You Shouldn't Go Further Than That
- One sentence covers several different numbers on this cooktop, so the part it names is a starting point rather than a diagnosis, and the difference is found with instruments.
- A control module reporting internal errors may act on settings inconsistently, which on an appliance that makes heat is a reason to isolate it rather than keep trying.
- The module is under the glass top, and the glass top is sealed into the counter, so there is no owner-side inspection to make here.
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.
