Honestly, critters are definitely a pain, but in my experience, it's usually a relay or a loose connection before it's something like chewed wires. People jump to blaming rodents, but I've found way more issues with old relays or corroded terminals—not as exciting as a chipmunk, but way more common. If the thermostat's not talking to the heater, I always check for voltage at the control board first... saves a lot of crawling around in dusty attics unless something really smells off.
Had a job last winter where the homeowner swore up and down it was mice chewing wires, but it turned out to be a crusty old terminal on the control board. I get why folks jump to critters—I've seen some wild nests in ductwork—but yeah, most times it's just something simple like a relay or a loose wire. I always check for voltage first too... saves my knees from crawling around for nothing.

- Can't count how many times I've been called in after someone's convinced themselves it's a rodent problem, only to find a corroded terminal or a fried fuse. Folks love blaming critters, but honestly, it's usually just wear and tear or a loose connection.
- Checking voltage first is just common sense. Saves time, saves your back, and honestly, most of the time the issue's right there in the open if you know what to look for.
- Not saying critters never cause trouble—I've pulled more than a few nests out of vents and found chewed wires in crawlspaces. But if there's no droppings or obvious signs, I don't go hunting for ghosts.
- Homeowners get fixated on the weirdest stuff. Had a guy swear up and down that his dog was turning the thermostat up at night. Turned out the anticipator was set way off and the contacts were pitted. Sometimes it's just old parts doing what old parts do.
- If the heater's ignoring the thermostat, my first move is always the basics: power, connections, and a quick look at the board. Nine times out of ten, it's something simple. The rare times it's not, then I'll start thinking about critters or something more exotic.
Honestly, you nailed it—start simple, check the obvious, and don't let yourself get sidetracked by wild theories. Homeowners mean well, but they're usually just guessing.
Had a call last winter where the homeowner was convinced squirrels had chewed through something because the heat wouldn’t kick on. Turned out to be a loose wire at the control board—took me longer to move their storage boxes than to fix it. Ever notice how folks always jump to the weirdest conclusions before checking the basics?

Happens all the time. People hear a noise or something stops working and suddenly it’s squirrels, ghosts, or some wild theory. Nine times outta ten, it’s just a loose wire, tripped breaker, or dead batteries in the thermostat. I get it—nobody wants to crawl around checking the obvious stuff, but it saves a lot of hassle. I’ve had folks swear up and down their pipes were “haunted” when it was just air in the line. Always worth starting simple before blaming the wildlife.
