Dacor ETT304 Repair: Common Problems and Model-Specific Service Guide

When the technician arrives at a Millennia electric cooktop, they will ask three simple questions: which zone reports the fault, how the touch controls behave, and whether the cooktop heats at all. The Dacor ETT304 can show a lockout that makes a healthy zone look faulty, so note whether the lock covers everything or only one zone. Write down the order in which the symptoms showed up. A zone that stops heating during a cook is a different story from one that reports an error at startup. Across the metro areas we cover, that order gives a technician a clear sequence to follow. In the booking form, enter ETT304, the zone involved, and the error code shown.

ETT304 is a Dacor electric cooktop from the Millennia line. The model number is printed on the rating label, usually on the underside of the unit; many owners also have it on the warranty card or installation papers; match it letter for letter before booking.
