Here in North Texas, we’re a little spoiled by the not-too-cold winter temperatures. We get our once a year snowfall, but generally our low’s are still above freezing. This was not so 2 days ago, when the low, including the wind chill factor, was to dip into the single digits.
I’m always cold, but it seemed unusually cold in my house. I thought, “Great. The heater is acting up again.” This usually means a trip out to the garage, flip the breaker, mess with the thermostat, then up to the attic, all in efforts to find the right combination of flipping switches on and off to achieve heat. This has been a ritual since I moved in the house 4 years ago.
This time, the ritual was to no avail. The heat was out and it was not going to work. I don’t know much about gas furnaces, but I do know a little bit about electric ones. Mine’s gas. And, of course, these things only happen during extreme temperatures. I called my friend **Keith, as he and his twin brother own a heating and A/C repair company. I knew it would be the next day before he came out and we decided to stay the night and bundle up warm. It seemed like a good idea at the time…
My oldest decided to sleep in his room upstairs, the youngest in my bed. A little after midnight, the fire smoke detector starts going off. *I had turned off the heater before going to sleep, knowing something was seriously wrong with it. The smoke detector turned off before I had a chance to get up and deal with it. Again, a quirky thing in my house, this alarm has been malfunctioning for a couple of years now. It’s in my son’s room, the one that’s sleeping upstairs. If you think these smoke alarms will wake your kids, think again. It’s right over his bed and did not wake him. After it went off for the 7th or 8th time, and finally wouldn’t turn off, I figured I better go deal with it. I moved my son to my room, got the ladder out and took it down, trying to shield my ears from the piercing sound. And yes, I checked to see if it was also a carbon monoxide alarm, and it’s not.
Keith called me back in the morning, and just to be sure, I changed the batteries in the thermostat, cleaned the contacts and tried again. Nothing. Keith came out, and the culprit was the main circuit board. You can see the spot where it blew out on the green side. On the flip side, there was another bad spot which had started to burn under the resistors to the right. So, which news would you like first, the good or the bad?
Bad news: The circuit board is fried and needs replacing. This is not only the board for the furnace, but for the A/C as well.
Good news: My house didn’t catch on fire. Continue reading
