LG Washtower Dryer No Heat

[Tylerrc34]

Hey fellow handymen and handywomen. This is my first post on here but I'm glad to know there's a place to talk about fixing appliances, I've been fixing my own appliances even before I had to. As a kid I would take them apart to see how they worked.

But I'm stumped on this one so far.

Just bought a second hand, very lightly used LG Washtower, model WKE100HVA, and plugged it in using the older 3 prong cord and it turned on but I could feel there is no heat coming out of the vent. And after the dryer spins for about 3 minutes it shuts down and shows an error code nP which according to the internet means "no power". I used my multimeter and checked for 240V coming in to the back of the machine and yes, it does have power. The next thing I checked were YouTube videos and found one that said the thermal switch can fail. So using my multimeter, I checked three things... 

1) Thermostat. There are three wires. It had continuity on all terminals.

2) Thermal cut off switch (or at least I think that's the name of it). This has two wires. They had continuity.

3) Heating element. This has three wires. I looked up the OHM specs and supposedly they are supposed to be 20, 20 and 40. Each set of wires measured correctly for OHMs.

I included three pictures. One picture is the back of the machine where my wires attach (yes I know they're routed on the outside, I had to do that temporarily) . The second picture is from the top showing a control board of some sort behind the power coming into the machine. The third picture is inside looking at the heating element, on the left is the thermostat, the next is the thermal cut off and then the three colored wires (red,yellow, blue) going to the heating element.

 

The question is... what should I check next?
