transformer failures
Hey
I have a Beckett AFG oil burner in my house. Last year or the year before the transformer failed and a tech replaced it. It was a Beckett Model BLL101 10kV. The tech swapped in a Beckett 51771U which just failed last week. I put a screwdriver on the springs and there was no spark so I went to the store and got a new one installed it and I had fire again.
Are these 2 different transformers direct swap parts or should I expect my new one to fail in a 2009 too? Thanks for any tips.

Ignition Transformer Failures
The 51771U is the electronic replacement for the old 10 kV iron core. Make sure the furnace is properly grounded & scratch some paint off of the transformer around the screw holes where is mounts to the burner chassis. Bad grounds are a common cause for electronic parts failure.

Iron Core vs. Electronic
Iron cores are far more forgiving of incoming voltage fluctuations. I have some very rural accounts where voltage fluctuations are a problem & have had to use iron core transformers.
