Hello,

Like the title says, the oven of my Monogram 30" dual-fuel, model ZDP304NP7SS, has stop heating.
It started gradually in the last few months by not reaching the selected temperature until this week where it stop heating completely accompanied by a smell of molten plastic.

Except for the three pairs of heating elements, everything works. The lights, fans, doorlock, display, electrodes are all OK. I have continuity on all elements.

I inspected the range relay board and found out the K14 relay was melted and burned. The printed circuit board did not seem to be dammaged. I took it to a repair shop where they replace the falty relay (with a 24VDC instead of a 18VDC!?!). After reassembly, I confirmed the relay was working as it is switching from 120V to 240V when heating was selected. And when selecting all modes of Bake, Broil, Convection, etc, I can hear the other relays clicking.

But this did not solve the problem. None of the heating elements are heating.

Any ideas?

Thanks

Problem solved, I replace the relay board. I ordered it from PiecesReliable.ca for 205,05CAD (about 165USD). I also replace the two oxydated wires that were connected to the main relay (K14) as they carry the current for all six heating elements.

Thank you all
