is this electric or gas? if it is gas and a newer model it has an ignitor that heats up that will then ignite the gas burner, the ignitor is bad or you may need to inspect and clean the gas ports on the burner as they can get cloged up over time, try the inspection and cleaning first. If it doesnt appear to be cloged then turn on the oven and watch the ignitor, if it doesnt heat up to be white hot then it is bad or going bad and should be replaced. if it is electric check to see if the heating element is working by turning the oven on and watch for it to glow red hot, if it doesnt then it will need to be replaced.
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.
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.
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.
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.
most likely you have a bad ignitor,pull out the racks and remove the floor to the stove,turn on the bake,if the ignitor glows but it takes more than 40 seconds for the flame to light you have a bad ignitor even though it glows and if it doesn't glow at all the ignitor is bad,also if the broil lights on top and the bake doesn't change out the ignitor.next time send the model number and i can look up your machine to help you better.
The ignitor is bad again,if it (ignitor) comes on but no flame/heat its the ignotor again, what would make the ignotor go bad so fast (usually last 10-15 years) is a problem with the oven burner, so now BOTH the ignitor and burner would need to be replaced,if it is 15 years old the ignitor is readily avaliable but the burner may not be
I am assuming this is an electric oven? If you have an ohm meter you can verify that the bake or broil element is good by measuring the resistance across the element. If it reads short then the elements are bad. The more expensive problem which usually tends to be the case is the oven controller board. There are to relays that control the high voltage current that is supplied to the elements. When the oven is turned on a signal from the oven controller activates the coil on the relay and closes the contact allowing current to flow to the element. There are two relays, one for broil and the other for bake. Try the oven on broil to see if that element heats up. If it does it could be the bake element, if it doesn't you till need to get a replacement oven controller board. They usually call them timer modules or clock modules. Good luck!
Thanks for choosing FixYa and welcome. If 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 defetive 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.
your ignitor could be going out. the ignitor has to get hot enough in order for the gas to turn on and heat your oven. if your ignitor is going out, sometimes it doesn't glow hot enough for the gas to turn on, or it could be that is takes longer than normal to get hot enough to turn the gas on. I would replace the ignitor and that should solve the problem. Joe
