The current issue is that it will spark the pilot arc but not continue
to burn (it's like it blows it out, or something doesn't cycle...bad
transistor or relay?)...I cannot find anything about the schematics

and a $80 labor bill.

If you put a daub of fingernail polish on
all the parts, you'll know the one that they
