Double oven... top works great, bottom has power but will not heat. No codes showing. Have had ohm meter on it and all is functional to elements. GE Profile model # JKP56BOA1BB, older model... maybe 1999.

CHECK FOR CRACKS IN THE BAKE ELEMENT. IF THE UNIT IS NOT HEATING THE BOTTOM, BUT THE TOP IS STILL HEATING, YOU MORE THAN LIKELY HAVE TO REPLACE THE ELEMENT. THIS IS A 220 VOLT OVEN WITH 110 VOLTS ALWAYS GOING TO THIS ELEMENT, SO TURNING OF THE BREAKER IS VITAL FOR SAFETY PURPOSES. WITH AN OHM METER, UNINSTALL THE ELEMENT AND CHECK BOTH WIRE CONNECTIONS FOR OHMS. YOU SHOULD GET SOME KIND OF READING BETWEEN 10 OHMS AND 500 OHMS. IF YOU'RE NOT AT LEAST GETTING A SOLID READING, REPLACE THIS ELEMENT.

the broil element
is the heating element that is found at the top of the oven and produces a very high heat for broiling. If the broil element isn't working, you should first do a visual inspection for signs that the element has blistered or separated. If the element appears normal then you can check for continuity with a multi-meter. Remove power from the appliance before performing this test. Remove the back panel and locate the terminals for the broil element and inspect the terminals and wires for signs of overheating or damage.

If there is no continuity then the element will need to be replaced. If the wires are damaged then they will need to be repaired. If the element is ok then you will need to check the broil circuit to determine the cause. This involves live voltage checks and should only be performed by qualified persons. Components to check include fuses, if the range is equipped, and oven control thermostat or electronic control. Depending on the manufacturer of the element, you will normally read between 19 ohms and 115 ohms


The bake element
is the heating element that is found at the bottom of the oven. Most electric ovens use both the bake element and the broil element in a bake cycle, with the bake element performing 90% of the heating. If the bake element isn't working, the oven may not heat. To help determine if the bake element is defective you should first do a visual check. If the element is blistered or separated then it should be replaced. If the element appears to look normal, then turn the oven on to a bake function for a minute and then turn it off.

Check the element for signs of heating and if it is still cold then it may be defective. Disconnect the power and then remove the back panel. First check the wires as they may have become loose or corroded. If the element appears to be fine visually, test it for continuity with a multi-meter. ( by placing the each of the meter prongs on each end of the heater element connectors) If the element is burned or no longer has continuity, it will need to be replaced. Depending on the manufacturer of the element, you will normally read between 19 ohms and 115 ohms

The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.
I offer free advice bcuz God is so good!

Sounds like the bottom element, or element wire in the top oven is burned out, Check to see if the element is broken, or swollen. Two signs of a burned element.

check that u have continuity through the elements if you dont then replace the element next if you do have continuity through both elements check to make sure you have power coming from the main control to the element if you dont have any power leaving the control board then replace the control

Usually, when an oven won't heat, it's because the bake element is burned out. The bake element is the black, pencil- thick tube at the bottom of the oven. When the oven heats, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it.

Its the thermal safety switch. When it trips - it cuts any power from reaching BOTH elements. Open the oven door - at the top wehere the oven latch is - remove the long black panel. In the middle - on the right is a small cylindrical switch...push down on the top - in the very center...it will rest the switch (like a circuit breaker) and then reassemble. Just did it on mine (2nd time) and it fired right up. Good luck

remove heating element an check with ohm meter. pretty simple really.

I suspect a heating element in the oven has burned out. Some ovens have 2 heating elements, one on the bottom for baking and one on the top for broiling. If this is the case, you can try setting the oven on broil and see if the top element gets hot. Usually the bottom element fails first because food gets dripped on it. In most cases you can unplug the old heating element by just pulling on it and plug the new one just as easily. You can check the resistance of the heating element with an ohm meter. If it's burned out the resistance will be very high, probably greater than a mega ohm. In some cases you will need to take the back off the oven to replace the heating element. Just make sure the oven is unplugged and cool when you start working on it.

chances are that the element is bad but with out more info on like what kind of thermostat you have if digital display if any codes like f-1 show this would be first thing i look at check power at element 220 volts should be at element if so element is bad (replace) is not you need to find the wiring diagram and follow it back and check voltage and ohms you will need a volt ohm meter for this.
good luck

Had a similar problem. The overheat sensor had failed to the open position and the oven control would light up and you could set the temp, but it would drop to 100 degrees and then go blank.
