My dryer is about 2 years old and is a Whirlpool Model No. LER8648PW0. It is not heating. I've cleaned the lint and checked the outside vent and it is not clogged. What could possibly be wrong?

I assume that is all that is wrong with it and the motor/drum still runs.

Flip your breaker off/on slowly a couple times, sometimes one side of the breaker can open without tripping the breaker. Your heater runs on 240, the motor runs on 120 volts.

Try all different settings/cycles to see if that makes a difference or at least give some help with troubleshooting.

Other possibilities are timer, thermostats etc., etc.

Check to see do you have 240 at the receptacle. You will need a meter to do this.
You can get a decent digital multimeter for under $20.00, you do not need fancy.
It is nice if the leads are a couple feet long. If it saves you from ordering one unnecessary part, it has paid for itself.
