I just replaced the element, hi limit thermostat, and seal on a 1300 series countertop pizza oven. 240 volt/single phase. I recommended replacing thermocouple as well, since I believed that is what caused oven to burn up element and hi-limit. Customer chose not to and a few days later the oven was burning pizzas and eventually shut down opening the hi-limit thermostat. The hi-limit is supposed to reset and close when you push in the reset button, but the previous part and new part would not. I was wondering if someone with a little more experience could tell me if this is common for this part, or is it normally resetable. I have a thermocouple and a new hi-limit I am about to replace. I have ohmed the potentiometer to make sure there were no dead spots and it checked out OK. Also I am curious if there is anything else I need to check that cud be causing unit to keep calling for heat when it should be satisfied.
Any advise may be helpful.
