All my fryers aren't lighting. They all spark but have no ignition.
Hey Jim! Check the main gas valve. If all of your units are not lighting this might be the issue. I hope this helps!
Can you see the spark or are just hearing a sparking sound. Could be a failing gas valve, no gas, spark gap is too far and is not sparking or has a very small spark because the igniter is too close to the burner.
The more specifics the better, since its "all of them" I would assume an overall gas issue. could be your regulator or a vent limiter in the regulator if it has one.
Hope it helps,
