Viking Designer Cooktop Code Ft: Sensor Failure With a Small t

What Ft means

On Viking Designer DETU series touch-control radiant cooktops, Ft with a small t is another temperature sensor failure code, the same meaning as FE. The control stops all heating elements and shows the code on the timer display. Because letter case matters on these cooktops, a small t is not the same as a capital T, so tell us exactly what the display shows.

Common causes of Ft

Temperature sensor failed
Sensor connector loose
Control not reading the sensor

✓ One safe check you can try

1. Turn off all controls and wait for the glass to cool. 2. Dry the touch area. 3. Switch the breaker off for a minute and on again. 4. Touch the on key. 5. If Ft stays, do not use the cooktop and call us.

! Why to stop there

Sensors are beneath the glass
Only a meter shows whether the sensor or control is bad
A cooktop without a valid sensor cannot be trusted to limit heat

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

FtFt questions

Are Ft and FE different problems?

They share the same meaning, a temperature sensor failure. They may point to different sensor positions, so we read both codes carefully. The two are treated as the same family by our technicians.

Can I cook while Ft shows?

No. All heating elements are stopped while this code is displayed. Use another appliance until the cooktop is repaired. A cooktop with a failed sensor is not safe to run, so please switch it off at the breaker if needed.

Will you tell me the price first?

Yes. You receive a written price before any work, and the repair is covered by our 30-day workmanship warranty. Any quote we give you comes in writing, and the work is covered for 30 days.
