"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

In many cases, you can sell your house if it has aluminum wiring, but you are likely required to disclose that fact during the sale. In some cases, your city or area may have banned the sale of homes with aluminum wiring, so you’ll need to update the wiring or arrange for its replacement as part of the sale. In some cases, it will benefit your home sale to replace the wiring system before putting it on the market.

Yes, you can get shocked while using a multimeter if:

  • You touch the metal tip while testing a live current.

  • The meter isn’t properly rated for the voltage.

  • The meter picks up on transient voltage that’s above the range you’ve set.

  • The meter has defective parts.

You can prevent shock and personal injury by using a multimeter properly and maintaining your device. 

If you’re unsure how to use a multimeter or want help with your project, contact a local electrician to get the job done.

Yes, many remodels include electrical upgrades for lighting, outlets, or charging stations. Confirm with your contractor.

You can distinguish the amplitude and voltage of most outlets by looking at the shape and positioning of the holes. Other features like buttons, switches, and USB ports help identify electric outlets, too. Use labeled images, like the ones we’ve included above, to cross-reference with your outlets.
