Questions & Answers

For Samsung Cooktop Service Switch Set (Part Number: OEM21088464)

William for Model Number MRES30S

The (large) dual burner element on my Dacor MRES30S cook top does not respond properly when attempting to turn on that burner. When it comes to the other 3 burners, I barely have to touch the glass and I get a beep followed by the corresponding (and pulsating) level selection. Upon selecting, the working 3 all fire as they should. When it comes to the (large) dual element it requires excessive pressure to get it to beep and fire up. Even then it will not allow the selection of the secondary element on the burner (no matter how hard I press on that option). I am curious if the sensor that reads selection for that burner is bad or if the dual element is more likely bad and requires replacing. Like I previously mentioned, the internal (inside) element will fire up if you apply enough pressure but it is excessive (the secondary or outer element option will not respond at all).

Hello Norbert. Turn off the power. Remove the cooktop from the cabinet. Remove all the sealed burners and knobs from the cooktop. Then remove the cooktop from the burner box. Now you can access and replace the microswitch on the unit.

Hello Alex. The model number you provided CABP3 is not for a cooktop. It is for a blower motor. We will need the model number for the cooktop. Thank you.

Hello Gary, This is going to be a limit switch at the top that is not making or maybe the switch isn't contacting mechanically. We cannot find a wiring diagram on the unit so, the tech sheet should contain this information. It should be affixed to the unit where it is accessible for a service man. It may be in a plastic or paper bag or it could be a sticker on the units' body under the counter. If you can locate this diagram, the issue will be the upper limit switch.
