Troubleshooting an Oven: Doesn't Maintain Temperature
There are a number of reasons why you may find that your oven doesn't maintain its temperature, and troubleshooting oven heating elements is not too complicated, so you should be able to manage this in a few hours. When you are trying to decide what is the cause of your oven not maintaining its temperature, you should be able to identify the different problems, and also understand how to repair the oven without too much difficulty. If you find a lot of problems, then you may need to provide a different solution, for example replacing the heating element and fittings completely.
Heating Element Is Broken
This is perhaps the most common cause of the oven not keeping the temperature is that the heating element is damaged in some why. The fact that the heat still comes on is a sign that the element is working, but it may lose heat if the connection is incomplete, or loose. The heating element can be removed and replaced easily, and this is perhaps a very good idea if you have any problems with the heating system of your oven.
Test the heating element by firing up the oven with the door open, and your hand close to the front of the element. You should be able to feel it warming up and staying warm, so if it starts to cool, take of the screws which hold it in place, and then unplug the connections. You can take the heating element to a store and they should be able to replace the part for you.
Thermostats Are Broken
The connections on your oven which set the temperature can be damaged easily, and if they are loose or broken, then they may be affecting the ability of the oven to tell what temperature you require. Pull out the oven setting switches, and then take off the panel which is just behind them. You should now be looking at a set of electrical wires and connections. Check that each of these are working correctly, and if there are any loose parts, fix them with a solder iron.
You may also replace the front panel if this has become cracked, and is no longer able to hold the switches. You should also look at the thermostat connected to the oven, and remove it and test. If it does not warm up correctly, then you need to replace this.
Electrical Connections Failure
If your oven is suffering from intermittent temperature failure, then you may find that you need to check the electrical cords and plugs which send power to your oven. A loose connection here can mean that power to the oven is not consistent, meaning that the temperature of the oven fluctuates. The problem might lie in the electrical system which is connected to your oven. Unplug the cable, and try putting it into another socket.
You should also check the plug to make sure that none of the wires are loose in the connections, and the fuse is still functioning. You can also remove and replace the power cable completely.
If these do not work, then you may have a major problem with the electrical connections inside the oven, and it may be best to leave it completely, and call in an expert, or have the oven replaced with a new one. This troubleshooting guide for your oven that doesn't maintain its temperature will get you cooking again.
