Often, this will be due to the element. The easiest way to troubleshoot is take a matching
element(if possible) from the other side of the stove top and see if that works in the receptacle.
There should be some letters after the model numbers you listed. The last three letters also lets me know what type of top you have on your stove to guide you through how to access the parts. Make sure you write the full number with all the letters before ordering parts.
If you have the glass top or ceramic model, the connections are different than other types. The manufacturer warns customers and nonservice personnel to never try to lift these cooktops. If you would like to pursue changing or testing this element despite that caution, there is a picture of an element and switch below.
On some flat top models, you need to open or take off the over door
before you can lift the top. Most stove tops will then lift off, but you
may need to take off a screw or two.
Also, on Canadian models, the front two burners will not operate during oven cleaning mode. If you are a Canadian user, try to reset your burner by turning on and off at the breaker. Canadian users should also make sure that the timer is not set and open the oven door fully to make sure toasting is not engaged.
Porcelain cooktops simply lift from the front and are held open with metal supports. Replacing coil type elements on models with drip bowls (not flat top) is very easy; you simply pull out the element and replace with a new one that can be purchased in large chains and appliance stores.
You should check the receptacle and wiring underneath the stove top for signs of visible dirt, grease or other abnormalities such as burns or frays. Turn off the power, and make sure the wiring plugs are tight.
Make sure the plug in end of the coil element is not burnt or damaged. Check the coil for rough or discolored spots. Follow the wires under the stove top that plug into the coil receptacle to make sure that there are not burnt, frayed or broken areas on the wire coatings.
Testing the element for continuity and possibilities like the receptacle and infinite switch
requires special tools. Testing the
infinite switch would be extremely dangerous as it is done live with
240 current (unless you live outside the US). If you have testers, you can check the integrity of all of the above.
Another less likely cause for elements not working is the knob that controls the burner being damaged on
the inside. You can pull a different knob to see if that works, but
this kind of issue is usually obvious because it does not fit snugly
and has play when you turn it.
Finally, if you are going to replace the element, or replace the receptacle or switch, make sure that you take the old ones with you with the full model number. Before pulling wires, take a digital picture or mark wires with
tape/paint so that you remember how to reconnect.
Check your parts before leaving the store, so that uninformed clerks do not steer you wrong. If you need further info on how to remove and replace the items shown, leave comments. But, take a look under the hood first, because you might be surprised at how simple it all is. I hope this helps
