DECU156

Viking DECU156 45-Inch Radiant Cooktop

Most common issues on this model

  1. Radiant zone staying cold
  2. Controls unresponsive after moisture
  3. Cracked or chipped ceramic glass
  4. Zone staying hot after switch-off

The DECU156 is a retired Designer Series electric cooktop, 45 inches wide, built into the countertop with a radiant glass surface. A top this wide usually sits in a kitchen where the cooking area was a priority.

With more width comes more elements, switches and wiring, and each one can age on its own schedule. We typically meet owners who say one zone has gone weak while the rest are fine. We find the cause by testing power at the cooktop, measuring the suspect element, and then checking its control. A wide glass top also needs a careful look at its edges, since chips can grow into cracks.

The repair is usually quicker than owners expect once the failed element or switch is identified.

DECU156DECU156 questions
Why would only one zone on my 45-inch cooktop stop working?

Zones are wired and switched separately, so one element, switch or connection can fail alone. We test that zone from supply to element and replace just the failed part.

How do I clean the glass without damaging it?

Let it cool, use a cleaner made for ceramic glass, and avoid scouring pads. Do not slide heavy pans. Scratches collect dirt, and chips at the edge can lead to cracks.

What if the cooktop smells hot when I turn it on?

A light smell from new residue is common. A strong or persistent odor can point to a connection overheating. Turn it off and call us so we can inspect the terminal block.
