The reset button on our oil furnace needs to be reset every 10 to 14 days. What can be the problem? We are leaving for the holidays and I'm concerned that we could come home to frozen pipes.

When was the last time you had it cleaned? Also, it could be a fan motor that eventually overheats and trips the reset.

Cad cell could be dirty or failing, a check and service could be just the fix for just under 100 dollars.
