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?
