Dogs chewed my low voltage wire


Maybe this topic has been done before, but i am having problem getting my ac back on. Here's what happened
1. Replaced the 240 line conduit that was chewed and was successful.
2. Replaced the low voltage line that was chewed and was successful.
3. The next day they chewed the l.v. line again, which I replaced again the same way i did before (Used an 18/2 thermostat wire and connected blue to white and brown to red just as it was installed).
4. After replacing it the second time the unit did not kick on when called on by either thermostats, but the manual button on the transformer does start the unit.
I have not used a volt meter yet but I wonder if there was a fuse blown seeing that there is no nick or cut in the wires and good connections on the spliced in wire.

I appreciate any help.

I know your question isn't about the dogs, but rub Tobasco sauce on the wires. It won't hurt the dogs, but they won't want to chew the wires anymore.

I'd use an ohm meter first and check the wires for continuity.

Check the circuit board in your furnace, might have an automotive type fuse that has blown. Should be 3 or 5 amp fuse. Don't go bigger than what it's rated for or you could wipe out the board. If you don't have a fuse the transformer is probably shot.

In which case, depending on the relative price of a new 'former and of a fuse+holder, add a fuse to your new 'former.

Do you need help with your unit or the dogs?

Break out your voltmeter and check ohms or for continuity. It is possible you have a broken wire since I'm guessing they may have nibbled elsewhere.

I too am surprised they chewed through a 240V line, and are still here.

I ended up crawling through the attic and replacing a 3 amp fuse on the heater and it did the trick.

Planning on building a barrier around the ac unit, but will a fence block out too much air from the unit? HVAC is not my field but it seems like blocking the air might do more harm than good.

As far as the dogs they must be able to sense something when it comes to the wires because they only chewed into the green #10.

Yes, anything that blocks air flow will impact performance. Something like chain link fence should be okay.

The other option might be to wrap the wire with something they don't like, or run it in conduit.
