Gas Ovens

When it comes to the gas oven there are two variations with possible additional features. A gas oven is a very simple device. It has a thermostat to regulate the temperature and an igniter to start the flame. When you turn your thermostat to the on position it sends voltage to the igniter. Depending on the brand and type of gas oven that you have it will either make a ticking noise which is a small direct current spark- which will ignite gas or it will be quiet indicating likely a ceramic igniter that heats up to a glowing brilliant yellow which is hot enough to ignite gas that comes in contact.

Many people claim that gas ovens are inherently more dangerous due to the risk of explosions and fires. I have seen far more fires from improper installations of ovens in regards to their power supply wiring. A loose wire is a major fire hazard for the electric equivalent of these compared to that of a Gas Appliance. On many Gas Appliances the gas flow is regulated using safety checks before allowing the gas to enter into the unit. If certain electrical components such as an igniter do not reach required currents the gas valve will not open.

Let’s talk about longevity and repairability!

A gas oven has very few components which are readily repairable even 20 years after the date of manufacturing has ceased. Many of the components on these units use common parts such as the gas safety valve, ceramic igniter, and thermostats. The gas fittings used in production are very Universal and can still be obtained for appliances built over 30 years ago! The most common failure of any gas oven is failure to ignite- this is likely indication of the ceramic igniter failing and preventing gas flow. Some gas ovens use electronic spark technology to ignite the gas and if it doesn’t ignite within a set time it ceases the gas flow. When the spark ignition units fail to ignite it is likely the control board at fault that has internally shorted out, preventing the spark from reaching the end of the wire where the gas flow is located. 

If you have to push a button and set a digital temperature you likely will have a spark igniter. Likewise if you have to turn a dial to set the temperature you will find most have a ceramic igniter.
The cost to repair a ceramic igniter oven normally is far less expensive than that of any other oven.
