Inquiry (采购产品): heater We have a model WH-80 (model 93-H56-017020) Patton Electric vertical electric heater. It has worked well the few times we used it over the past several years. Today it buzzes whenever we whenever we change the control knob. The power light and the reset light come on but not the heat light. I thought maybe we needed to push the "reset" button but can't find one. Any idea what our problem is?
