I have a GE dual wall oven model JTP27BA3BB. When I turned the lower oven control knob on and to the warm position, a minute later I heard that ominous 60Hz hum and then smelled burned electrical components. Based on the parts diagram for this unit I believe the Oven Thermostat (part # WB20T10001) burned up. I would like to disaassemble and determine if this is acually the case. Can anyone direct me to a sevice manual and/or wiring diagram?
Also what is the typical failure mechanism for this part?
