![]() However, it still under testing/development. ![]() It may be overkill for your application especially if a purpose built piezoelectric gas ignition system but I can publish the current prototype circuit if it interests you. The spark appears to be able to jump at least a 6mm air gap which I can alter if necessary by changing the charging time of the capacitor, its charging voltage and its capacity (currently 4.7 uF) It is controlled by an ATTINY85 and is triggered by PIR detectors which should be suppressed if the car is in motion. Piezos do occasionally refuse to work due to damp weather or altitude but my guess is that the number one stove failure is forgetting or losing your lighter. Find the igniter box where the igniter itself is contained, and unscrew the front panel. The prototype is on an a 7cm x 9cm solder board and it powered by 4 x AA cells. Make sure the grill itself isn’t hot and that the gas supply has been turned off altogether. If the igniter fails, the burner will not light. In principle, it is based on a 200 volt power supply of a type used for nixie tubes, which charges a small capacitor, also a small thyristor based circuit similar to that in a CDI (capacitor discharge ignition) and a small ignition coil intended for a 2 stroke motor which I bought for a couple of bucks on aliexpress. Hold down the gas control knob and keep depressing the piezo igniter button at the same time. ![]() My simple fix for my Weber Charcoal Grill not lighting. It is a sort of electric fence type application. How to Fix Gas Grill Igniter No Spark Piezo Ignition Troubleshooting QUICK FIX Push Button Igniter. One current project of mine is a high voltage spark generator actually for the purpose of discouraging Martins from entering the engine bay of my car because of their habit of gnawing through cables etc.
