I have a Beckett RWB, Danfoss BFPH fuel pump 3 GPH, G8184R4009 primary, with a solenoid valve.
Problem: Ignition failure when the aquastat calls for burner to turn on; what happens is the pump turns on, and the motor turns on, but the electronic transformer does not spark AT ALL, so the photocell registers "zero flame" and trips the primary. This happens intermittently, about 1/40 ignition requests from the aquastat. The transformer will spark after several attempts pressing the reset button. The filter has been changed, as have the nozzle, and strainer, and the electrodes replaced and adjusted to spec.
What can be wrong? This electronic igniter is 2 months old, an HX-002. Its springs are touching the electrode rods the way they're supposed to. The electrode tips are spaced to spec, and it works all day, but then once in a while the transformer does not give a spark. The problem persisted with a new primary installed. Is it the transformer, should I be testing something else? HELP!
