Tell them it is interfering with your AM radio reception... you can suspect
that maybe a ground wasn't reconnected, or maybe a bolt isn't holding it tight
to the case, or maybe a dirty connection, or even possibly a cut wire or a hv
wire too close to some metal that is arcing. In any case it shouldn't
interfere, especially to AM radio or an audio system.

Subject: [RFI] Interference from Oil Burner Ignitor
I recently had the igniter fail on my oil burner. The replacement was an
Allanson 2275-U as per the bill. The interference comes through over top of a
station on the AM Broadcast band (KYW-1060). Its also getting into one of my
FM rigs and/or my audio distribution system. I can figure out which one it is
as soon as I can walk again (burst Baker's cyst). I can tell it’s the heater
as I hear it start and at same time the tick, tick, tick, tick, sound comes
over the AM radio. The noise lasts for about a minute and burner continues to
fire. There is a logic circuit built into the heater that deactivates the
igniter once circuit is sure the fire is burning. I believe that is why the
noise stops before burner shuts down.
The old igniter was RF quiet when it was working. Probably even quieter once
it failed.
This is a new install done on 11/27. I have not paid the bill yet, so I have
some leverage with the service company. I think the igniter would be
classified as an un-intentional radiator. Any thoughts on how to proceed?
Bob
