First let me apologize if this has been covered I searched and could
not firnd a similar post.
I have an oil furnace with an indirect water heater attached. My water
heater recently went bad and I called a plumber to replace it, and
while he was there tuneup my furnace. The next morning I had no heat,
the plumber was away and did not have an emergency contact, so after
six hours of waiting for a call-back I called my oil company to service
the furnace. The tech determined no spark and a bad ignotor. After
replacing the ignitor still no spark, bad relay? After replacing the
relay everything worked.
I have two questions. 1. Could something the original plumber have
done have caused the bad relay / ignitor. I know nothing he did is
directly related to the relay but has anyone else ever seen anything
2. Who is responsible? The original plumber, or me, or is it a shared
