bath fan noise

Replace Your Bathroom Fan

If the bath fan in your home is more than 20 years old, chances are it’s pretty loud. A loud fan may be good for masking bathroom noise, but the jet engine roar is downright annoying the rest of the time. Worse yet, your old bath fan may not be moving enough air to keep your bathroom free of mold and mildew. Newer-style bath fans, on the other hand, are so quiet you can hardly hear them running, and they cost very little to operate. It’s easier than you think to swap out that noisy, inefficient bath fan.

Repair a TV Remote

If one of the buttons on your TV remote doesn’t work, and you want to avoid the cost of a replacement remote, fix it yourself. Most remotes have electrically conductive paint on the bottom of each rubber button. The more you use each button, the more the paint wears off. The good news: You can buy a repair kit that includes two-part conductive paint.

broken phone charger fix

Liquid Electrical Tape Can Rescue a Phone Charger

Charger cables for cell phones usually last only a few years before the insulation starts fraying on the ends. Replacement cables cost $8 to $30, but there’s a cheaper solution. If the insulation is cracked but the copper wire inside is still intact, try covering the crack with a couple of layers of liquid electrical tape ($5 to $10 per bottle). Performix and Gardner Bender are two brands that get lots of positive reviews online. Just be sure not to let the cable touch anything until the liquid tape dries completely. Plus: Check out these 38 amazing handy hints you can do for less than $5.

Listen to Music While Solving an Electrical Problem

I like to have my switches and outlets labeled, so it’s easy to figure out which breaker to shut off when I need to change a switch or outlet. When I moved into a new home, so I had to label everything. I didn’t have a helper, so I used a radio instead. I’d just plug it into an outlet and blast some music. Then, I’d flip breakers until the radio shut off. I had everything labeled in an hour. – Collin Grace

Simple Hack to Save Your Phone Charger

To make your otherwise fragile phone charger last for more than a couple of weeks, try out this simple hack! Start by removing the spring from a pen. Next, stretch one end of the spring out a bit so it can fit around the charger cable. You might need to use pliers for this. Now, wind the spring around the cable until it is completely on the charger cable. Next, take appropriately sized heat shrink tubing and slip it over the phone charger and spring. Use a lighter to warm the heat shrink tubing until it conforms around the charger and spring. This simple hack will keep the cord from breaking any further or from even breaking in the first place! Oh and, learn why you should never put your phone in rice and how you can dry it out instead.

Add GFCI Protection

A GFCI (ground fault circuit interrupter) is a shock prevention device that’s required by the National Electrical Code in certain outlets, including kitchen counter outlets. Older homes built before code requirements went into effect usually won’t have them. And it’s a good idea to add them.

We recommend that you avoid unnecessary complexity. Simply replace outlets with GFCI receptacles. Remember to check the electrical box sizes when you do this and to upgrade any box that’s too small.
