Kenmore 110.66862500 dryer runs full cycle but no heat

The full model number is 110.66862500

The dryer will run a full cycle but the heat never kicks on.

I have checked the vent and air flow and they are all good.

I checked the continuity on the timer, thermal cut offs, thermal fuse, and heating element and they all check out fine.

There is scorching on the connectors of the heating element.

What have I missed or what did I most likely do wrong?

1st check that you have 240 to dryer. Will run on 120 but will not heat. Turn breaker on and off a couple of times. Where power cord connects to dryer make sure cord is not burnt there. Usual reason for no heat is hi limit thermostat or heater element. Hi limit thermostat is the one on top of heater box. Let us know what you find.

I checked the outlet and got a good 240, I plugged in the machine and tested where the cord connects and also measure 240 there. I pulled the high limit thermostat and the heater element and they both show as having continuity.

Check the heating element for continuity. Next check the thermal fuse. Check the high limit thermostat then the cycling thermostat.

Either timer or motor centrifugal switch. Don't have wiring diagram but in console there should be one. Find which wire comes from motor to heater might be red or red with white strip.With wire unplugged from thermostat or heater with dryer running should have 120 volts. If not make sure that the other end at timer has 120 volts, leave wire unplugged to test. Fairbanks may have some ideas when he comes in.

May be faulty timer contact. Can read good with simple static continuity test but fail under high heater coil current load. Unplug dryer, disconnect wire from timer terminal BK that goes to timer motor. Unplug red wire from R terminal and plug into that BK terminal. Plug dryer back in and see if it will heat. If so, faulty timer. Otherwise, you didn't mention checking the operating thermostat. Could be that or faulty motor switch as mentioned. Safety device at top of heater box is thermal cutoff, not hi limit. Hi limit is at bottom of heater box.
