My Roper Stackable Dryer is not getting hot. Do you think this is the heating element? If so where can I pick up a new part and how easy is it to install?

Could be the element, could be the controls. I would make sure it is getting power before buying a new one. Easiest way to check is with a voltage detector. Just a matter of opening the cabinet, disconnecting the element, and replacing it. If no local appliance parts supplier has parts, try http://www.applainceparts.com/

To do simple checks like this you do need some tools. A test light, a meter, or a voltage detector might be the best place to start with. I came across the niftiest gadget for trouble shooting, a voltage detector. They work through the insulation of wires. There are several brands. I have a GB Instruments GVD-505A, less than $15 at Home Depot. Touch it to a hot wire, and the end glows red. Find the doodad that lights it on one side, and not the other, and you have the culprit. You do not have to open up housings and expose electrical contacts. You are looking at where your hand is, not where the meter is. Most people are capable of doing repairs and will get it going and not get hurt if they use a little sense. The voltage detector makes it even easier.
