Following recently increasingly frequent but random oil burner lockouts, the solenoid coil was eventually found to have failed completely.
To provide some context, simultaneous problems with organic matter restricting the oil flow had masked this problem (the oil pump was replaced 3 years ago so wasn't the prime suspect). After clearing the pipes and verifying adequate oil flow (including through the pump), on reassembly the burner refused to ignite. As it was now after hours, in a desperate attempt to placate my wife and in the absence of a spare Danfoss coil, I fitted the coil from the (seized) Suntec oil pump that had been replaced maybe 20 years ago. It was necessary to add some washers as the Suntec coil was a few millimetres shorter.
Slightly to my surprise, it worked.
My question is whether this arrangement can be considered a permanent solution or will there be any damage to the valve/stem resulting from using the 'wrong' coil? I've read that Danfoss pumps are good but the coils less so and the opposite about Suntec. Have I now got the perfect solution?
