Depending on how it is wrongly wired, it might appear to work or appear not to work. There is a severe risk of electrocution whenever switches are incorrectly wired. Get an expert to check it and rewire it properly. If this switch is not right, perhaps all the other circuits should be checked too!
I remember my ex-husband "trying" to wire a new light switch in the bathroom. Thinking he knew what he was doing, he tried wiring it like you would a wall receptical.
He routed the hot wire to one end of the switch, and the neutral to the other end. (shows how much he knew)
When he turned the breaker on, and flipped the wall switch, WOW, you should of seen what it did.
The wires literally jumped about 7 inches high near the junction box, there was a loud "thud" and the breaker naturally tripped.
I tried to tell him that you actually split the hot wire that is coming from the breaker box to the light itself and put each an end on each side of the wall switch, and the neutral runs from the breaker to the light and doesn't go near the switch at all.
I told him that it's not the same as a wall receptical, but dummy wouldn't listen.

The light switch might still work, but it could be unsafe. Incorrect wiring could lead to short circuits, electric shocks, or even fires. It is best to have a qualified electrician correct any wiring issues to ensure safety.
Dim lights after a switch replacement could be caused by using the wrong type of switch, loose wiring connections, or issues with the electrical circuit. Check that the new switch is compatible with the light fixture, tighten any loose connections, and ensure the circuit is providing the correct voltage. If the issue persists, consider consulting a qualified electrician for further troubleshooting.
Dimmer lights may not dim if the dimmer switch is incompatible with the type of light bulb being used. Certain LED and fluorescent bulbs are not compatible with traditional incandescent dimmer switches. It is important to ensure that the dimmer switch and light bulbs are compatible for proper dimming function.
The furnace can be but it is not a good idea. Safety code requires a disconnect switch outside the area where the furnace is situated. This switch is used for an emergency shut down in case something electrically goes wrong with the furnace. In modern homes these furnaces are wired to a dedicated 120 volt circuit from the distribution panel. From the panel, the circuit is routed to the safety switch. From the safety switch, the circuit then continues to the furnace load.
If the Hunter fan-light's light is not turning on/off with the remote, it could be an issue with the remote control or the receiver in the fan. Try changing the batteries in the remote control first. If that doesn't work, you may need to reset the remote and receiver by following the manufacturer's instructions. If the problem persists, you may need to contact Hunter customer support for further assistance.
No, it will be dangerous. Electricity is very dangerous and installation codes are not written simply to make things work but to make them safe. There are many electrical situations that will work fine even if wired incorrectly. The determination of what is correct or incorrect is what is most safe if something goes wrong. So the question one should ask is not, does it work. But ask the question, If something goes wrong, is this the safest way to have wired this circuit. Only competent electricians who are familiar with and fluent with applicable codes can sufficiently answer this question.
