Hatch Pro Tip of the Week:
Have you ever noticed a light switch stop working all of a sudden? Its a common problem in old and new houses, especially when renovation work has recently been done. Sometimes contractors work quickly and forget to tighten down all the screws to light switches or electrical outlets which results in a short circuit and could lead to a fire in your home. When both ends (including the grounding wire) are not screwed down tight enough the circuit is not complete and causes electrical arcing.
The best thing to do when you find that a switch is not working any more is to go to your circuit breaker panel and flip the circuit breaker for that switch (if it hasn’t been flipped already) and leave it off until a licensed electrician or skilled handyman comes to repair it. If you don’t turn off the circuit breaker and the light switch is flipped up (or in the “on” position), you could continue to have electrical arcing and possibly cause a fire.
I found this situation at a rental property recently and I was able to successfully replace the switch with a new one.
