If the problem with your Maytag electric dryer is that is not heating at all, the problem could be a bad high limit thermostat.
This thermostat is a safety device use to open the heater circuit if the heater box gets too hot, due to no air circulating inside of the dryer.
Before replacing this thermostat you will need to make sure that the airflow through the dryer is good, or the thermostat will burn again too soon.
