No Power to Stove
One of the most frustrating problems with a Jennair stove is when it will not turn on. To verify that the stove is not working, check the oven light.
Use the switch on the oven to turn the light on and see if it illuminates. If the light does not come on, unplug the stove and plug in another appliance to test the outlet.
If the outlet is not working, a fuse may have blown out, or a circuit may have tripped. If the outlet has power, you know that the problem is with the stove and not the electricity.
When a burner is out completely, it is relatively easy to isolate and resolve the problem, but when a burner works sometimes and not others, the problem can be harder to nail down. If one or more burners on your stove's cooktop show erratic performance and heating issues, it is important to remove the burner element and check the connection.
If the burner's connection is damaged, it could cause problems like erratic or uneven heating, or even periodic burner failure. Use a flashlight to examine the connectors for signs of damage -- if you see evidence of burned or flaking metal, that connector must be replaced.
Cooktop Works, Oven Does Not
If the cooktop works fine but the oven does not bake properly, the most likely problem is a worn-out baking element. You may be able to see signs of damage on the baking element, including flaking metal or burned spots.
Even if damage is not readily apparent, the element could be going bad -- to test it, turn the oven on and watch for the baking element to come on. When the element is on, it should be glowing red -- if the element has dark spots, it is most likely going bad and must be replaced.
