My electric dryer stopped heating. I have checked & double checked continuity on the heating coils, both thermal fuses, hi-limit thermostat, and the thermostat with five lugs (I get continuty on the opposite end lower lugs). All check out ok. What else could it be? I checked the outlet and have 240v across the two side lugs, 120v between others. It appears that the heating system is not getting power. Could it be a moisture sensor, conrol knob, or what????? HELP! BTW, I get 0 ohms across the lheating element leads, and I have disconnected one side of all things before I measure.

The problem seemed to be that the circuit wasn't getting any power; I checked power at outlet, it was good. I finally opened the terminal block access & found that the light blue wire attached to L2 (red wire form outlet) had separated from the mounting lug and was just hanging. Turns out the nut holding it down was loose & the loose connection melted the solder at the wire where it connected to the lug. I installed a new lug to the wire, tightened all connections & the dryer works fine! I'm just glad it didn't result in a fire or other calamity! Thanks for your help; I learned a lot about how this dryer works (too much!).

You're correct about the bias heater lugs. The way the thermostat works is that it has continuity between the two larger lugs, so that electricity can flow through it to the heating element. When a certain desired temperature is reached, however, the click you hear is the bimetal contact bending away from one of the lugs, breaking the electron flow to the element. In normal operation, as the thermostat cools, it clicks back into its normally closed position, again allowing electron flow. Check it when it's cool by separating it from its wires, and checking across the two larger lugs for continuity.
