Hi there, we've got a black smooth glass KitchenAid separate 36" electric cooktop, full model # is KECD865HBT4. I'm not sure on the exact age - we've been in our house 7 years, and it was installed when we moved in.

The circuit breaker it's on tripped yesterday, and it looks like there's a continuous short. If we flip the breaker to On, there's a pop & flash from the knob in the lower-left position (the one that controls the dual 1000/2400W burner).

I've removed the glass cooktop to expose the elements, etc, and can't see any obvious scorch marks.

My questions are these:

• could anyone please forward me a link to the repair manual?
• any idea whether it's more likely a switch or burner is at fault? Or possibly something else?
• anyone know how many ohms a "good" element should be reading?
• any other ohmmeter tips on how to tell if a switch is OK? (I did see the link in the pinned post about checking the switch for continuity with L1/H1 & L2/H2)
• we also had a cleaning service in yesterday, I don't know if a cleaning product could've caused this...

Thanks very much!!
