The following link explains how to troubleshoot a dryer no heat problem:
The first thing you should check is your wall receptacle voltage to ensure you are getting between 220-240 VAC across the HOT leads (LEFT and RIGHT slots). If your input voltage is wrong, the heating circuits will not operate, but the drum still may turn. That's because the drive motor only requires 110-120 VAC, while the heating circuits require the full 220 service. If the voltage at the wall receptacle is good, check the again at the terminal block in the back of the dryer. This is where the power cord is installed. Check across the RED and BLACK terminals for the same 220-240 VAC. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord. If the voltage is bad at the terminal block and wall receptacle, check your circuit breakers. Some installations have two breakers controlling the dryer. If one trips, the dryer may run, but won't heat. If the voltage is good at the terminal block, your problem is internal to the dryer. This may save you the need to open the dryer if you have an external problem.
On your dryer, the heating element is located inside the dryer under the drum on the right hand side.
In most cases the Thermal Cut-Out (TCO) fails before the Heating Element. If the TCO is defective, it is strongly recommended that you replace the Hi-Limit Thermostat at the same time. These two components are commonly sold as a set and are located on the heater box on the left hand side. The TCO is located on the end opposite the heating element terminals, while the Hi-Limit Thermostat is located adjacent to the heating element leads. Failure to replace both components may result in premature failure of any components you replace.
Make sure you take all resistance readings with the components unplugged to isolate them and prevent parallel resistance paths. If you do determine your heating element to be defective and need to remove it, please post back and let me know. I hope this helps you.
