Question about Kenmore Ovens
Your problem seemd to be from the very simple ones.
The first for both coils you need to replace the infinite switches, their internal contacts are damage by years of use.
For the oven is a similar problem but you have to replace thermostat knob for the same reason.

Hi, well elements are very easy to test, you need a multimeter set to OHMS, now the elements should have a resistance equal to OHMS law for the Wattage.
EG: 3000 Watt element, Mains Voltage 120 V AC, therefore, to get the Resistance = First, we must use a two stage calculation, extract the Amps, from the Watts, (Formula, Watts divided by Voltage), then we divide the Voltage by the AMPS to get the Resistance in OHMS,
OK so, 3000 Watts, divide by the Voltage, 120 V AC, this then gives us, an answer in AMPS, of 25 AMPS.
Therefore we have 25 AMPS. Now using OHMS law, to find Resistance we must Divide the Voltage by the Current, that then equals, 4.8 OHMS. This is the resistance of a 3000 Watt element, This also factors up and down, so if the Voltage stays the same. 1000 Watt = 14.4 OHMS --- 5000 W = 2.88 OHMS. 10000 Watts = 1.44 OHMS.
As Resistance goes down, the Current & Wattage goes Up.
Right now you can measure your elements, to see if they are OK.
As related usually they go open circuit, if so, then with the mains ON, and the Element switch ON to FULL, we should have a Voltage across the terminals of the element itself, more or less the full 120 V AC. MEASURE VERY CAREFULLY.
Usually elements that do not work are Open circuit or a Very high resistance.
the only other place that we may have a problem is in the actual element controller itself.
For best DIY results one simply must get a service manual. find your one at this link below.
