Check that the intake air vents are clear it must be able to breath freely and that the hot air can get away freely this is the most comon thing to pop the thermal limiter,,the only other part that will blow the limiter is the heating coils if they are geting to hot becouse of a short in a winding

LG electric dryer is not heating. Electric coils test for continuity. Any suggestions?

There are several things that can prevent a dryer from not heating. UNPLUG DRYER BEFORE TESTING ANYTHING.
1- power- Test the receptical to make sure you are getting 220 volts. To do this you need and voltage tester. Both legs should pull 110 and together 220. If one leg is not pulling any power than your breaker is half tripped. Reset breaker to cure your problem. If problem persist it is in the breaker or receptical.
2- cord- To test this unplug dryer. Take the panel covering the cord connections off. Remove cord entirely from dryer. Test each leg for continuity. If any are not showing cont than replace cord.
3- Themal fuse- To test this remove access back access panel on some front panel. By the blower housing there is a fuse white thin sliver or round fuse with 2 wires going to it. The one with 4 wires is your low limit cycling thermistat. The thermal fuse is near that. Disconnect the 2 wires and check fuse for continuity. If meter shows cont fuse it good. If not replace fuse.
4- Hi Limit Thermistat- test same way as thermal fuse. On the heating element housing at the bottom are 3 wires running to a fuse. Test the left and right. The bottom is attached to one of the sides.
5- Thermal Cutoff- Test same way as thermal fuse. This fuse is near the top of the heating elemnt above the Hi Limit. 2 wires with usually plastic covers on them.
6- Heating Element- Below high limit 2 wires. Test for continuity.
If all these fuses are good than you may need to call a technician. The motor may not be getting to the right rpm to activate the senfrigrial switch in the moter. Timer or control board may be out.
7- Motor- If

Problem: The dryer runs fine but it won't heat up. I have checked and cleaned the vent line. This did not abate the problem. Question: is there something other than a bad heating element that would...

If the heating element is fine check the limits:
Your fuse is ok because the dryer runs. So one of the heater limits is probably blown.
The 2 above limits fit a standard WP dryer. Yours might take a diff part number depending on the model. If all limits are fine, yall could have a bad breaker, a bad temp control or a bad timer.
