Question About Furnace 80D36-19A
will not light all the time...

I am questioning the Prepurge fan. the diagnostic light is "13". Some times it lights with a laoud sound. can I clean the prepurge fan (it looks like there is a gasket around it. can I get some?). could this be the problem, or should I look at...?
