Netaheat profile 60e - Pilot light won't light

[Neal]

I have a Netaheat profile 60e

Symptoms: No main burn No pilot light Fan is running no 'sparking sound' to be heard The 'cutout' (?) button on the bottom is not out (in the past, the boiler has occasionally cut out, and this button pops out. Pushing and holding it in relights the pilot, and then the main burn)

Any ideas??

first thing you should look at is the air pressure switch as that is next in sequence, check for split pipes or blocked conections, hope that helps pete
