How do you trace a wire in the wall?

There are two kinds of stud finders that can help you find wires in a wall – magnetic and electric. A magnetic stud finder is used to detect metal nails in wall studs. Electronic stud finders produce a tiny electrical field that changes when the finder reaches a denser region in a wall.

    What happens if you wire a thermostat wrong?

    Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.

    How many wires should a thermostat have?

    The most basic thermostat has 2 wires; usually a red and a white wire. Two wire thermostat wiring is used for furnaces only and usually doesn’t need a “C” or “Common” wire. That’s why we only need two wires: Red wire for power (24h).

    What happens if you wire a 2 wire thermostat wrong?



    If you get it wrong, the heat will run continuously. Once you have them paired, attach one pair to “24VAC” (R) and the other to “Heat call” (W) on the thermostat. Doesn’t matter which one, since the thermostat just shorts them either way.

    Why is my thermostat not turning the heat on?

    The most common reasons for such a problem are a dirty filter, thermostat malfunction, pilot ignitor, wrong settings, or low battery issue. In such a case, all you would have to do is clean the device, double-check the thermostat settings, or replace the batteries.
