This worked well. I pulled the cover off to look at the wiring, and noticed it had batteries inside. I put new ones in, and it came back to life. Magic! But here is the thing: I’ve obviously never put batteries in this thing, and neither has my wife. It is 14+ years old. Unless the service guys, who fixed the thermocouple module in the furnace about 10 years ago, or Everlast who serviced the furnace a few years ago, put batteries in, it has ran on the same set of AAs the whole time. Is this normal, or some sort of record?
