I have cleaned the lent traps and made sure there is good air flow with no obstructions in the vent. I have replaced the heating element and it still will not heat. Frustrated, can anyone tell me the nest step. Should I replace the High-limit thermostat. Thanks

YOu Should test componets before condeming and replacing. Test the limit switch to see if it bad. Do you have access to a multimeter and know how to use it?

Yes I can borrow one from my neighbor. I will check the thermal cutoff and the thermostat.
Thanks
