2. How To Install an Over-The-Range Microwave Oven

The first step before installing your over-the-range microwave, is to install the vent through the wall or cabinet, if indeed you are venting the fumes outside. Your new microwave oven comes with an installation template that will help you mark the appropriate spot on the wall or the bottom of the cabinet to make a hole for the vent. Please read on...

3. Kitchen Appliance Connection Requirements

Kitchen appliances require specific needs such as junction boxes for electrical connections, disconnecting means, and dedicated circuits for specific appliances. The National Electrical Code requires that fixed appliances have their own (dedicated) circuit. These separate circuits are specific to appliances that must remain running at all times, like freezers, refrigerators, ranges, electric water heaters, and clothes dryers. Please read on...

4. Three Circuits Used in Homes For The Laundry Area

It is commonplace for homes today to have one or more of three different laundry circuits. Each has its own unique assignment for supplying power to the laundry appliances. One is a 20-amp circuit designated to run the 120-volt power for the washing machine and the control power for the dryer. This circuit can also supply general-use devices. It is wired with 12-gauge wire and is usually type THHN or THWN wire. This is a dedicated circuit for the laundry room only. Read on...

5. Why Your Oven Won't Heat Up

If you turn the oven on and it doesn't heat up, it could be that your oven ignitor has gone bad. You see, when the oven control is turned to bake, the ignitor turns on and starts to glow a bright orange, that is if it is working properly. When functioning correctly, the ignitor gets hot, the gas valve opens and sends gas through the burner. The ignitor lights the gas coming from the burner and the oven begins to heat.

However, if the ignitor doesn't glow hot enough, the oven will not light and you'll likely smell gas. Don't worry though, the gas valve is equipped with a safety mechanism that detects a gas leak and shuts the gas valve off, if it is working properly.

6. Wire a 4-Prong Dryer Outlet

If your home is not already wired for a 4-prong outlet or if the feed is not equipped with two hot wire, a neutral, and a ground wire, you'll need to run a new wire to feed the outlet. Install a 10-3 NM wire that has a ground wire included from the breaker panel to behind the dryer. Leave enough slack at each end to allow for proper connection.

Older homes have a 3-pronged outlet that has two hot terminals and a neutral terminal, operating without a ground connection. The 4-pronged out let is much safer.

Connections of electrical clothes dryers shall be made with a 4-conductor cord and 3-pole, 4-wire, grounding-type plugs or by Type AC cable. Read on...

Your gas oven is a modern convenience that cooks the food while you scamper around the house. You just plop the roaster, pizza, or casserole in the oven, set the temperature and turn it on bake.

10. How to Change a Bake Element in an Electric Oven

In order to get the right bake element for your electric range, you'll need to have the model number for the appliance store or repairman in order for them to look up the proper part. The model number can be found on the inside of the bottom pan drawer. Pull the drawer out and look for a white or silver tag that states the model and serial number. This will ensure that you get the right replacement part. Read more...
