Several years now, the thermocouple on the boiler has
crapped out on only the COLDEST day (thus far) of the year.

Again this year too -- this morning, pilot was out,
and it wouldn't relight. And temp outside was 17(F)!

(Window in boiler-room is open a few inches, due to
air-flow problem -- we have a fan in the pipe that goes
up the chimney.)

Now, in the past, replacing the thermocouple (plumber did the work)
would fix it.

Question: just wondering -- any substance to this
apparent correlation between
super-cold temperature and crap-out of thermouple?

question: would placing electric heater near the boiler
possibly help?

Thanks!
