I repaced my heating system 4 years ago with an oil fired Weil Mclean

These guys are butchers. They change parts and charge a lot of money
and they are not sure what the probelm is. They dont know how to test
the parts to see if they are defective.
Anyone have aclue about what the problem could be?

Do you have a voltmeter? If so, just monitor the output voltage from
the transformer when things are normal, leave it hooked up, and at the
next failure check the voltmeter to see if it is still putting out the
same voltage. This is basic, if you don't understand then find a
helpful handy neighbor.

Likely most home meters cannot handle the typical 10 kV output from an
oil burner ignition transformer.
