Question about Dacor Millennia ETT365 Electric Cooktop
No responce? could this be the touch sensor? or somthing els?
Okay. I just solved this problem, using the suggestions by 'Guest'. Here are some improved tips to troubleshooting.
1. With the power supply ON, spray compressed air into the vents on the underside of the unit. This 'twitched' the contacts on our unit and turned on two of the burners, proving that it was indeed a contact problem.
2. After the unit has cooled down, with all of the 'reminder' lights off. Turn off the main power at the fuse box. You NEVER want to work with an electrical appliance's innards with power being supplied to it.
3. Remove the unit from the countertop. Turn it over and rotate it if needed so that the power supply is not tightly pulling it. Remove the two screws holding the clamp on the power supply wiring.
4. Remove the screws holding the two different boxes together, and the screws holding the main box to the unit. Lift up the two pieces separately, careful not to yank them apart.
5. Remove the ribbon connector from the green computer board. Open the teeth on both sides of the pin and remove it.
6. Using needle-nosed pliers, squeeze on the white plastic posts holding down the upper board. Lift the corners of the board up gently, working with one at a time. Gently remove the board.
7. Look for corrosion or contaminants. Spray the entire lower board clean with compressed air. Spray the entire upper computer board clean with compressed air. Gently replace the upper board onto the 4 white plastic posts.
8. Spray the end of the ribbon connector, then replace it into the upper board. Remove the other end from the main board and spray it before replacing it.
9. Gently touch all the connections, looking for any that have loose contacts. Do not pull on any wires. Spray the entire board, and the adjacent fan, with compressed air.
10. Reassemble the protective coverings and then the power supply clamp.
11. Return cooktop to normal position in counter.
12. Restore main power at the fuse box. The unit should send a series of lights through every bulb, TWICE. If this was the solution to your problem, it is now fixed. :-)

Before trying something bigger - take the thing out of the countertop & lay it upside down on a towel. Take apart the 10 or so short phillips screws around the periphery which hold the bottom cover on. Lift the cover up JUST A BIT (several connections between the halves) and you will see a ribbon connector between the circuit board that is the "touch sensor" panel under the glass and the main power switching controls. Try taking apart each end of the ribbon connection a few times and "cleaning" by going off & on the pins. The connector is very similar to that on a computer HD - just less pins. This procedure worked fine for me & brought evertything back to normal!!! Be careful putting things back together that all the high voltage wires are correctly routed and the 2 grommets inside the control box go back into place. This will all make sense when you open things up. Good LUCK! /KRK
