Possibly a tripped thermal fuse. Should be located behind the panel in between the upper and lower ovens. Might have a red reset button on it you can push down. If it clicks and then works again, look for possible cooling fan problems.

SOURCE: GE JTP 1580W288 Set oven to Bake, switches to broil at bake temp

The F2 Error code means the oven has detected an excess temperature condition. Most often this is due to a bad temperature sensor - the sensor costs about $75 from an online repair site. 
How to remove and replace the temperature sensor. In most GE ovens, when you open the door, you'll see the rod-shaped temperature sensor sticking out of the back wall at the upper left. It's about six inches long and a bit more than 1/8" in diameter, held in place with two screws. 

Turn off the circuit breaker (built-in ovens) or unplug the range before attempting the replacement. 

The replacement sensor will come with instructions, but basically it's a matter of removing the sensor, pulling out the wires to where they are connected and disconnecting them. You may have to snip. The replacement sensor will come with high-temp wire nuts to hold the new connection. Polarity doesn't matter; it's a straight resistance thermocouple. Hook it up, be sure you poke the connections back far enough so that they're on the other side of the thermal insulation and not resting against the back of the oven. 

If you continue getting the F2 error after replacing the sensor, then the problem is likely in the control module - this is the circuit board behind the keypad and clock. 

You'll need to remove the decorative bezel to get behind the control panel. Remove screws and set off parts in order - it's not complicated. Once the bezel is off there are two more screws that hold the panel in place. Then you can lift the panel up about a half inch and pivot it forward toward you. You'll see a bunch of wires going to a circuit board. 

On the panel you will notice some black plastic boxes that say "Potter & Brumfield" on them. These are relays. Check the relays - slide the black plastic cover straight up to expose the coil and the contacts. The coil, when energized, closes the contacts - look at all the relays. You can manually close the contacts with your finger (be gentle). If the contacts of one of them are stuck, they might be welded together. You can fix the problem by prying apart the welded contacts gently with a knife blade. Take some time to gently polish the relay contacts with a folded bit of fine grain sandpaper - this will get some more life out of them. Be gentle and careful - the relays aren't complicated but if you bend the contact or rip it out, you'll have to replace the controller, which will set you back a couple hundred dollars. If you unstick and burnish the relays, they will probably eventually weld together again as the rough spot will spark, but when you burnish them with sandpaper they should be good for some more life before they need to be replaced. 

If the problem isn't the temp sensor or welded relay contacts then the problem is obviously somewhere else, but temp sensor and relay contacts will account for the lion's share of F2 errors. 

Once again, be safe, be careful, be gentle. Ovens are not very complicated and they're tough, but always exercise care. Always disconnect electricity before messing with them.
good luck,

Hi.

Check the thermal cutoff. Remove the thermal breaker from the oven and use a multimeter set on Ohms to test it. If the part reads open (infinity of Ohms, same as on air), then you need to replace the breaker

Here the part:BREAK THERML
The part is indicated with number 353 in diagram below.

If the thermal breaker is OK it will read zero Ohms or very low impedance. In that case the next part to replace is the thermostat. The thermostat also called temperature sensor or probe, is located inside the oven cavity.Test the thermostat in a similar way to what you did with the breaker. If the thermostat is open at room, then replace it.

Here the part:Oven Sensor
The part is indicated with number 332 in diagram below.

Here the diagram. Click on the picture to enlarge:

Note. I could not locate the exact model number in database, please call the part seller and ensure that parts correspond to the ones used in your model.

Regards.

Ginko.

My oven will not heat up to temperature


It may be the bake element that has gone out. The self clean usually uses the broil element to heat the oven. And most oven will either put 120 volts to the broil element while baking or pulse the broil element while baking. This will cause the oven to get warm but not hot. Check the oven bake element it cound be bad or a wire may have burned off.

It is common to have the broil element pulse on or they will send 120 volts to the broil element to even the heat in the oven. Some ovens have a preheat function that will power the broil and bake simultaneously until the oven reaches temperature then the broil element will shut down. If they both stay on red continuously through the entire bake process then something is wrong. Probably a stuck contact on the control.

UPPER OVEN WORKS, LOWER OVEN DOES NOT, NOT ERROR CODE


THINGS TO CHECK:

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!

My bottom oven ( non-confection) will not go on-it will just sat 100 degrees but won't get warm or hot. Top seems to be working fine. This started after I tried to use the self cleaning feature.


If broil and bake do not work on your bottom oven, it is probably your lower thermistor or control board. If the bake works but broil doesn't or broil works and bake doesn't, it is very likely your heating element. With an ohmmeter, the heating elements should be about 40 ohms. Much higher or lower signals a problem. If you suspect the control board is the problem, they can be repaired quickly and reliably at www.fixyourboard.com

Kenmore electric range - oven temp low and takes forever to heat


if lower element tests open with continuity meter then it for sure is bad. i would also check the wire ends that connect to the element and/or the control board, they could have loosened allowing a bad connection and low voltage to elementor burnt off.. most ovens do not use the broil element at all during the bake cycle, only during the broil cycle.. some however do utilize the broil element during baking, but at a lower wattage or something..
best of luck,

Heating element on upper oven of a wall Thermador Oven


The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.

Delonghi range oven


Bake- Normal convection- both upper and lower heating elements.

Conv. Bake- Semi-forced convection- both upper and lower elements, heat is then distributed throughout the oven via the fan.

Broil- radiation- The heat is radiated by the ifrared broil element.

Broil & Fan- Radiation and Ventilation- The radiated heat from the infra-red broiling element is distributed throughout the oven via the fan.
