First, the thermal cut-off kit includes the high limit thermostat, do not order both parts from the graphic or you'll have an extra high limit thermostat.
Installed a new heating element and thermal fuse - that fixed the problem of no heat in the dryer. Ordered these parts as there was a slim chance it was one of them (they are wired in with the heating element). I'll be replacing these next, my dryer is almost 20 years old so a few new parts are not unexpected. These are all easy repairs that anyone should be able to do.
I will be returning the extra thermostat though - Appliance Parts Pros has an OUTSTANDING return policy!!!!!
