Some repair / testing tips to verify this is the part you need:
Before you jump to the conclusion that the element is bad make sure you test for 240 vac at the power outlet that the dryer is plugged into. If your not getting 240 vac from the to power leads coming in you have a breaker or fuse issue. If you are getting 240 vac and no heat you will need to test the heater parts.
The safest way to check the element is to run a continuity test on the element itself if you have access to a multimeter with a continuity option. You will need to unplug the dryer, take the vent off of the back of the dryer, remove all of the screws fastening the back panel onto the dryer, and remove the back panel. Once you have access to all of you heating parts including the heater coil on the back of the dryer, and you can run your tests. 1st, using a flathead screwdriver, remove the 2 wires that are connected to the terminals on the heating element. Turn your multimeter on, set it to a continuity test, and test between both terminals on the element. If you get no continuity (no beeping, no ohms reading), the heating element is no good replace it. You should be able to find a spot on the heater coil that is burnt in half. Make sure you clear your vent from the back of the dryer all of the way out of the house and the blower housing before using your dryer with the new element. Blocked air flow from lint build up is usually a big reason for problems like this.
If you do get continuity the element is good and you're going to need to run the same continuity test on both of the thermostats mounted on the same casing as the element. If one of the thermostats does not show continuity you will need to replace the cut off kit 279769.
If you do get continuity through these parts you will need to run a continuity test on the timer. Dryer still unplugged, remove the screws on the back of the control panel to gain access to the timer. Set the timer to 50 minutes on timed dry and test for continuity between the 2 terminals on the timer with the large guage red wire and large guage black wire. If you don't get continuity through the timer the timer needs replaced.
