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?
