Gas-fired heat transfer oil furnace will not ignite

Normally, it automatically ignites when the return oil temperature drops 3 degrees below the set point. However, since yesterday, it has failed to ignite; the entire burner system remains inactive. This has resulted in insufficient heating in the workshop. I’d like to ask the experts: what could be causing this failure to ignite?
First, consult the boiler manufacturer; the burner is generally linked to the outlet oil temperature. There is also a series of conditions for starting the burner; failure to meet any one of them will result in failure to ignite.
There are many reasons why a burner’s interlock system does not initiate automatic ignition; these can be process-related or equipment-related, with equipment issues being the most common. Examples include fuel gas pressure being outside the acceptable range, fuel gas containing liquid components, failure to pass self-check tests, and abnormal flame detection. If the burner shows no response at all, it is necessary to check the power supply and the interlock triggering mechanism first
It has been checked that the gas leak detector has failed to detect any leaks, so the burner does not operate
It was finally found that the gas leak detector failed to detect any leaks, so the burner did not operate; now that the detector has been replaced, everything is working properly
