Our Kenmore Classic Grille came with the house, is on an island, has side down-drafts and two (left/right) plugin modules. We use it in 4-burner hot plate mode.

The left rear hot plate is the only one that heats up reliably anymore. The right rear used to be reliable, but now it heats up slowly and doesn't reach high temp like it used to. The fronts work sporadically, but when they work they're also slow and don't heat up to high temp.

We thoroughly cleaned the contacts on the ceramic plug (female) but no change in behavior. I will test the other modules (grille and griddle) on both sides and collect that data, but the hot plates have been gradually getting weaker over the past year or so.

Any ideas? Where can I find the circuit that was so nicely described in the Ohm meter testing section?

Thanks!
