Check your breaker box to make sure the breakers are ON.. these typically are double throw breakers.. it is possible one of them has been thrown open.. so flip that double throw off and back on.. then check..I have seen one side of these breakers fail.. unusual.. but it happens.. then a replacement is in order.. regardless. visually it may appear the breaker is closed..but upon closer inspection.. one side may be "spongy/open". There are always exceptions..so examine the breaker box carefully.
If one breaker is open..it would be wise to keep an eye on things to determine how it got that way in the first place. If the breaker will not close or throws/pops again..you either have a bad breaker or a wiring problem..in some cases the element may have grounded out..or burned a wire.. etc.
Next thing to check for is a bad element.. Remember..this is a 220volt hot circuit with a high amperage breaker.. BE CAREFUL.. USE CAUTION.. Failure to do so could result in serious injure or DEATH.
Turn off power at the breaker box to the oven.. test the working over to make sure the power is OFF.
Remove the oven racks
Remove the screws at the base of the element
Pull the element toward you
Note how the wire(s) are connected
Disconnect the wires.. checking for broken or lose terminals..if lose or broken..repair.
You will need a volt ohm meter for the following..
Test the Element for continuity. Place each probe on the terminal ends (manual will have ratings) generally if you have continuity it probably works..
Test for a grounded/short.. one probe to element the other to terminal end..if you have continuity.. it's shorted out. Test both terminals
Replace with a new one if needed.. reverse procedure. Turn on the power .. and test for proper operation.
Again.. 220 VOLTS..HIGH AMPERAGE.. USE CAUTION..not doing so could result in injury or DEATH
After you have done the above..and get an all pass..then it's on to controllers and temp sensors.
Best of luck
