Dacor CER304 Electric Cooktop Repair

The CER304 is an electric cooktop in the Dacor Millennia series. That generation is still in service in many homes around the city, so we meet it regularly. An electric cooktop has fewer moving parts than a gas one, which concentrates faults in a few places: the elements, their switches and the power reaching them.

Problems we see

• One element stays cold while the others heat.
• An element stays on high regardless of the knob.
• The indicator light glows but nothing warms.
• The glass surface is cracked, chipped or marked.

Reading the situation

If a single element fails, the element or its switch is the likely cause. If every element fails together, the supply is the better suspect: the breaker, the connection under the counter or the junction. An element that never turns off is a safety matter and should be switched off at the breaker until a technician has checked it. Cracked glass also calls for stopping use, because spills can reach the electrics.

Counter and cabinet considerations

This type of cooktop drops into a cutout and is wired from below, often above an oven or a drawer. In older San Francisco apartments the wiring may be original to the building, so the technician looks at terminals for heat marks or looseness. Please clear the space below before the visit.

What you can safely check

1. Confirm the breaker is on and not tripped.
2. Wipe the surface clean and dry.
3. Try each element to see whether the fault follows a single knob.
4. Note anything unusual, such as a smell or flicker.

Burning smell, smoke or sparks: breaker off immediately.

Planning the visit

Mention which element misbehaves, whether the fault follows a particular knob, and what sits beneath the counter. Clear access below the cutout and a few minutes with the model label in view make the first visit much more productive.
