If your thermostat has a BROIL setting on it, then apparently your unit is residential one.  We don’t address residential appliance questions here.  Only commercial-grade equipment used in restaurants and such.

 

Wherever you might go to ask your question again, I suggest you provide a model number.  American Range made hundreds of models for both the commercial and residential markets.  There’s no way anyone can help you without your providing a good model number.
