CIT304KB

Thermador CIT304KB

What we most often repair on units like this

  1. Touch controls that respond slowly or lock up
  2. Cooking zone that quits after a few minutes at high power
  3. Keep Warm that does not hold temperature
  4. Cooling fan noise or a clogged intake
  5. Frame seam that lets liquid reach the electronics

A framed induction top like the CIT304KB tends to turn up in kitchens swapped from an electric coil range, because the 30-inch cutout is easy to match. The 40 A circuit gives it room, but older wiring from the former range can still be the weak point. We start at the junction box and breaker, not at the glass.

The stainless frame sits on the counter surface, so spilled water travels along the seam. That is a good reason to look under the unit if the touch panel has become temperamental. With 7,200 W across four elements, we then run each zone at medium and at PowerBoost and watch for thermal cutbacks.

The page for this number says no longer available and names no successor, so we confirm part numbers from your rating plate before we quote.

CIT304KBCIT304KB questions
Why does the cooktop stop after boiling water on PowerBoost?

The unit lowers power when its electronics run hot. If it happens quickly or often, the fan and airflow beneath the unit are where we look.

Is the Keep Warm feature part of the main control?

It runs through the same touch controller as the other functions, so a failing board can affect several features at once. We check the settings first, then the board.

Does the frame make repairs harder?

The frame can be removed for access, but it must be resealed. We handle that as part of the written estimate.
