Model Number: cce3401b
Brand: Jenn-Air
Age: More than 10 years

all of a sudden, none of the 4 burners (heating elements) on my jenn-air (maytag?) 220 v stovetop will heat up
power is on, indicator lights come on
i flipped the breaker a few times
i confirmed my other 220v appliances work find
there are no reset buttons, fuses etc. the entire thing is flat and sealed .. i just see the wiring to the junction box

what is common to all four elements that would make NONE of them work?

please help?
