There are lots of things which could cause an electric dryer to not heat, you can read about the most common ones at the following link. Each would have to be checked one by one until the cause in your case can be found.

If none of those are the cause, please post the dryer’s model *as it’s printed right on the appliance* and we’ll see if there are other possibilities on your model. You can find tips for locating the model and serial number tag on your appliances in the ‘Repair Parts’ section of my site linked below.
