How to fix a broken oven?
We all know how annoying it is when an important appliance doesn’t work. This goes double for your oven. What this article will do is help you troubleshoot different problems for both gas and electrical ovens. It will also teach you how to do (very minor) repairs on your oven.
What You’ll Need
There are two things that you’ll need when you’re trying to troubleshoot problems on your oven. First and foremost, you’ll need your owner’s manual. You should never, ever attempt to do any repairs without having your owner’s manual by your side.
The second thing you should have when trying to troubleshoot oven problems is a voltage meter. A voltage meter reads the current levels in the wires of your oven. You can get voltage meters in your local hardware store, big box retail stores and Internet retailers.
Your Oven’s Heating Elements
One of the most common oven problems are issues with the heating elements. There are two heating elements in most ovens. The first is the broil heating element, which is on top of the oven. The bake heating element is on the bottom.
You can easily tell if you have problems with one or both of the heating elements. When both elements are working, you can easily see a red glow in your oven. If your oven is warming but is not at the correct temperature, you should examine your heating elements.
If you determine that one or both of your oven’s heating elements are defective, you probably have to replace them. If you replace one or both elements and they’re still not working, you may have an electrical issue on your hands. At this point, you’ll need to bring in your voltage meter. Test all of the wires that lead up to the heating elements. The issue could be a bad wire or a loose connection.
Temperature Sensors
Almost all electrical ovens have what are called temperature sensors. This is simply a mechanism that monitors the temperature of your oven. You can tell if your oven has a temperature sensor by a digital display that usually comes on all models with this mechanism.
A defective sensor can cause your oven to have heating issues. If the sensor is defective, it may need to be replaced. Before doing this, check your oven’s heating elements and wires. Ovens that do not have temperature sensors use the basic mechanical systems to control temperatures in the oven.
You may also want to look at your oven’s thermostat sensing bulb. Make sure that this bulb has not burned out. If the bulb has burned out but you know that it’s still getting power, change the bulb. You also want to make sure that the bulb has not come loose. This is important as these bulbs have been known to loosen over time.
Gas Ovens
If you have a gas oven that’s either not heating correctly or not heating at all, you always want to check the bake igniter first. The bake igniter, located right next to the burner, could have burned out or it may be malfunctioning.
After you check the bake igniter, make sure that gas is actually getting to your oven. If it isn’t, you’ll want to check your igniter. You may also have a malfunctioning gas safety valve, so you need to check that out, also.
Determining Your Oven’s Correct Temperature
If you still haven’t determined the cause of the problem, you’ll want to check the thermostat and selector switch. The selector switch is what changes the settings on your oven, such as from oven to broiler. The thermostat could stick or be defective.
Your oven may need to be calibrated if it’s not cooking at the correct temperature. Your oven’s calibration dial will be located either on the back of your temperature knob or at the bottom of a small shaft. There should be an adjustment screw on the dial. You can use the screw to adjust the temperature.
If you want the temperature of the oven increased, turn the screw clockwise. To decrease the oven’s temperature, turn the screw counterclockwise. You should be able to either increase or decrease the temperature of your oven by 25 degrees with a half turn in either direction.
All you need to determine if your oven is cooking at the correct temperature is a temperature gauge. Put the gauge in the oven and set it to 350 degrees. Once you’ve given it time to heat up, you can determine if anything needs to be adjusted or not.
What to Do If Your Oven is Still Not Heating
If your oven is still not heating correctly, you may need to have the main control board of your oven replaced by your local Harrison Appliance representative. The representative may also need to look at the relays of your oven’s two heating elements. If either or both of the relays burn out, your heating elements will cease to work.
Before embarking on any repair job on your oven, you should not only have your owner’s manual at your side. You should also know what you’re doing when it comes to tinkering with your oven, especially a gas appliance.
Although some problems can be fixed once you consult the manual, other issues may require the technical know-how of a Harrison Appliance representative. If an issue seems too big for you to fix, stop what you’re doing and call a Harrison Appliance rep immediately.
