Super cold weather will cause your furnace to run more often but that should
not accelerate the death of the thermocouple.

Preheating the combustion air which comes from inside the house or garage
(is it as cold as outside where the furnace is?) will not increase the
lifetime of the thermocouple. It will only cause you to send money up the
chimney.

If your furnace is located in an area subject to full outside cold air, that
would be atypical and the cold temp may degrade some components due to
extreme thermal expansion and metal fatigue.

Maybe its not the cold, maybe it has something to do with conditions off
season (summer) like condensation that sets the stage for premature failure
when usage is at its peak.

Keep a spare thermocouple on hand and learn how to replace it.

Is it an older model with a full time pilot light or a newer electronic
model that ignites the pilot before igniting the main burner.

Maybe you were just unlucky.

Thanks for the reply!!!


Have THREE spares.

Is "older" (age 7 yrs, vintage 30yrs AFTER man lands on moon!)
without electronic pilot-starter.


Only problem is that due to construction of THIS (model) boiler,
changing the thermocouple is difficult indeed, especially
for big-handed guy.

Any equipment (or mirror-setup) to make it easier to do installation?


THANKS
