We have had a cold snap here the last few days. There is nothing unusual about that at this time of year, but it has been cold. We have had temps down to -19 below zero, and wind chills much colder. The reason I mention this is that the other problem with this has been our furnace. Generally, it works fine, but lately, especially in the middle of the night, it will shut off, and not start up again. I have awoken the last two, or three nights, in a row to a house that is at 60 degrees or lower. So far, we have been able to restart the furnace simply by turning it off and on again, but last night that took several attempts. I finally went back to bed, and the furnace came on a while later and warmed the house up. I think we have a faulty thermostat, but I'm not sure. I may have to break down and call a repairman. Maybe we'll just tough it out for the winter, and fix it for next winter. :o)
Stay warm, be safe. Stick.
