If the connections and wiring appear to be in order, then the issue may be inside the piezo itself. Obviously the connections should be secure and not loose, but check for other potential issues such as corroded pins or oxidized contacts. That said, there may be something else entirely wrong, so we recommend first doing a simple check on the connections between the piezo and the sound device. Generally speaking, there are two main reasons for a piezo not working: either there’s something wrong with the internal electronics of the piezo, or there’s something in the wiring causing an issue. It is hard to say why your piezo may not be working, as there are a variety of reasons it may not be functioning correctly. The cost of an electronic ignition system is generally higher than that of a piezo system, although it often provides better value in the long run due to its greater reliability and lifespan. Piezo-type systems generate heat faster than electronic systems, although the efficiency and longevity of their components is compromised by their need to be manually adjusted and replaced.Įlectronic-type systems are much less complicated and use fewer components, allowing for longer periods of time between maintenance. In addition to the type of spark generated, piezo and electronic ignitions differ in a few other ways.

This spark is generally more consistent and prolonged than that generated by piezo ignition systems, allowing for more complete, efficient combustion. Electronic ignitions use a spark generated by electronic means, such as an electronic coil. This spark is generated by vibration, which is also known as a “knock”. Piezo ignitions use a spark generated by using a diaphragm, which is amplified by a piezoelectric crystal. The main difference between piezo and electronic ignition systems is the type of spark that is used for combustion. What is the difference between piezo and electronic ignition? This makes them especially suitable for gas-powered appliances and other applications that require a reliable, quick ignition source. It also has a long life span, as it does not produce any wear and tear. The advantage of using a piezo igniter is that it does not require electricity, as it produces its own spark. This spark then passes through an electrode, which then ignites the gas that is released from the burner when the igniter is activated. In the case of a piezo igniter, a small hammer strikes a quartz crystal enclosed in the igniter, which generates an electric spark. This property causes certain materials to produce an electric charge when subjected to pressure or vibration. How does a piezo igniter work?Ī piezo igniter works by utilizing a property of certain crystals called piezoelectricity.

If you are noticing any of these issues, it could be a sign that your igniter needs replacing. When the igniter begins to wear out, it can take longer for the spark to ignite the burner, may not spark at all, or not stay lit for long enough for the appliance to heat up.

Gas-fired igniters usually have a ceramic or quartz component that is sensitive to heat and fuel exposure, so they do wear out over time. Some of the factors that will determine how quickly the igniter wears out is the type of gas, the model of appliance, local environmental conditions, and the amount of use the appliance gets. Many homeowners report needing to replace their igniter around once every two to three years. The rate at which they wear out depends on the type of igniter and its quality. Yes, igniters do wear out and need to be replaced periodically. However, it is important to note that the majority of piezo igniters require a resistor to limit the maximum current delivered to the crystal as too much current may cause damage to the igniter.Īdditionally, some piezo igniters do draw power from an external source such as a battery to control the voltage in the sparking circuit which can help reduce misfires or rapid degrading of the ignition coil.

The piezo crystal is frequently applied with a voltage of around 500V from its integrated electrostatic generator and has a very low power requirement.Īs such, it does not require an external power source such as a battery to produce a spark. Piezo igniters use a piezo electric crystal to create a spark when struck by a hammer, which then ignites the gas in the appliance it is used in. No, piezo igniters do not require a battery.
