JT930S0K1SS Won't heat up

Oven turns on but won't heat up. I have checked the voltage at all four heating elements. All I have is 120 volts. When I check voltage between two power supply leeds at one element I just have 120 volts. Power coming to the oven is 240 volts. Ohams is within specs for all four heating elements. I have replaced the main WB27T10551 power board. not sure where to go from here. Any help would be great, Thanks.

    If i go to the GE web site and look under find parts and I put in JT930S0K1SS part 407 is the board I replaced. https://genet.geappliances.com/PartsNet/... This board has five relays on it The limit switch? is this the switch that has four wires going to it and has the temp sensor so if the oven overheats it will blow right?. GE lists this part 156https://genet.geappliances.com/PartsNet/... If this is it, it does have 120 volts at all four wires while the oven is on. When you say 1K ohm at room temp, which of the four wires are you testing?

SOURCE: Ge oven jtp18 elements won't heat

The limit switch in a Ge oven usually works or is blown. I would look at the oven sensor located at the back of the oven. It should read approximately 1k ohm at room temperature.

SOURCE: GE OVEN JTP15WD1WW ELEMENT COMES ON BY ITSELF WITHOUT TOUCHING START

When you installed the control board was it part number WB27T10305? The reason I ask is because the problem that you are describing sounds like a stuck relay on the main control board, the part number listed above

Why All lights andfan is runing but oven will only heat to 30or 40


Either the heating element is faulty or you are not getting the correct voltage to the element. Here in the US, with the element removed, you should be getting 120 volts AC. You can use a meter to verify the condition of the element too.

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.

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!



On modern electronic control ranges, the oven temperature sensor
is the part that regulates the oven temperature. If it is not working properly it could be the reason why the range or oven won't start. This part can be found inside the oven on the rear wall near the top. Most modern ovens will display a fault code if the oven sensor is at fault. If you think the sensor may be the issue you can check the resistance with a multi-meter but will need to know the correct resistance of the sensor at room temperature. Remove power from the appliance before performing this test.

Most modern ovens use an electronic control board
to control the oven functions. These models will use the control board to operate the oven safety valve on a gas range or oven, and the bake and broil elements on an electric range or oven. If there is no power to the igniter circuit, or the element circuits, then you should check the control board to verify that there is power at the appropriate output relay. These are live voltage checks and should be performed by qualified persons only. If there is no output voltage then the control should be replaced.

The oven burner igniter
commonly known as the hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. As the igniter draws electric current it will heat to a high temperature and glow, as well as cause the bi-metal in the oven safety valve to warp and open the valve releasing the gas to be ignited. This sequence normally takes about a minute. Igniters come in both flat and round styles and are very fragile. If the burner does not light then you should check the igniter first. If the igniter does not glow at all, then check for power to the circuit. This is a live voltage check and should be performed by a qualified person. If power is present then the igniter may be open circuit and can be checked for continuity with a multi-meter. If the igniter is glowing, but the burner is not lighting, the igniter may be weak and still be at fault because it requires a certain amount of current draw to open the valve. This check requires the use of an amp meter and should be performed by a qualified person. If the igniter is defective then it must be replaced.

Oven won't heat up on Belling XOU60FSS lights and fan on.


1.Aclicking sound could be something wrong with a relay. Check for any loose connections around the main control board on your oven. The click you hear is a relay losing power and switching back on. If the clock resets then something is causing power interruptions to the board.
2.
3.Even a bad relay door switch will hinder your oven from operating.

If your oven has internal fuses, a wiring or component problem could have caused a fuse to blow. A blown fuse is an indication that a component has shorted or failed, and the problem will need to be corrected. Most ovens that use fuses will have an indication of the circuits that are affected by a particular fuse. If an oven fuse has blown, then you should inspect the oven element and the associated wiring to determine the cause before replacing the fuse.

Jenn air gas oven won't light off/heat up


Thanks for choosing FixYa and welcome. you have a electric oven or a gas oven that won't heat or doesn't heat properly, here are some things you will need to check. The most likely cause of a oven not heating correctly is a defective heating element. You have two types of heating elements in your oven. The bottom element(s) are the baking elements. The element(s) on the top are the broil elements. If you don't see the bright red glow from the element, chances are they are not working or not working correctly. If a heating element is bad, you need to replace the entire element. If your oven is warm and not correctly hot, one of the elements may be bad. In most ovens, when you preheat, both elements are used. This would make the oven to appear like it is working correctly but it is not. If the elements are not working, they might not be getting power. Test the wires to the elements with a voltage meter to make sure they are getting power before you decide to change them out. Many electrical ovens have a sensor that monitors the oven temperture. Ovens that have this sensor usually contain a digital display on the oven. The sensor could be defective. Those without the sensor use the basic mechanical system to control the oven temperature. You also want to check the thermostat sensing bulb. Make sure the bulb is good and has not come loose. Now, if you have a gas range oven that doesn't heat properly, first, you want to check your bake igniter. It may have burned out or it could be not working properly. It will be located near your burner. It is also possible that you are not getting gas to the burner. If so, it may be the gas safety valve or the igniter. You need to check your selector switch and thermostat as well. They may be defective. Always make sure you test the parts for power with a voltage meter of some type before you decide to change the part. If you have a part that appears to not be working, it may not be getting power because of a bad wire or broken connection.

Both the bake and broil oven elements do not heat up / they are unresponsive. I can set the oven temp but on the control panel and it appears that everything is OK there I've replaced both elements and...


Must check the the voltage of 240 coming in to the oven sometime there is 120 volts which will light up the control panel but not enough to turn on the heat elements also check the wiring diagram some times there are cut off switches between the control panel and heat elements those can be bad too!

Maytag elect. wall won't bake nor broil


I suggest checking the voltage going to elements. If there is no current, trace wires. Not exactly sure if there is a fuse/relay on your model. If there is current, than the elements may have gone bad.

My single glasstop oven


Will try to help here.. First off.. when you measure 120VAC at each terminal for the heating elements..what are you using as a reference? Ground? Since your stove is probably wired 220VAC, I would expect to see something across the two terminals to the element that isn't line voltage.. meaning, when you turn the controller to a setting, you should see something more than 120VAC across the terminals and the current will be controlled to maintain a heat setting. The burner that has an open element is indendent so that should not factor in. Heating elements are nothing more than a big resistor that generate heat when current flows thru them. Just because you have one leg of power doesn't mean you have current flow thru it and therefore that is where I think your problem is... You may have an open leg ..Check the power coming into the oven and make sure you have 220VAC across the two line voltage terminals.. Be careful ( very careful ) when doing this...
Hope this helps.

OLD GE Wall Oven doesn't heat properly


On these older ovens ther is usually always 120 volts on the elements at all times.
If you check across the element ends with it in bake you should read 240V. If not, there is a problem with the control. With the voltage drop you describe, it sounds like you are losing power on one line of voltage coming to the element.
Post back to let me know what you find out or if you have any questions.
