My wife called me at work - (yes, I walked the 9/10's mile again today)
furnace man arrived .... and left.
Burnt out oscillator component (??) on water circulator.
(fuel oil, with circulating, hot water radiators -
built 1902 - new furnace & boiler 2004)
Replaced part, now working, its fixed..... Hooray for small miracles.
Cost? ...$0.00 ... covered in our policy
