Hi @natetheegreat
Assuming that you mean the oven temperature, here's the [document|42095|service data sheet] that may help.
It describes how to calibrate the oven and also what resistance value the temperature probe will exhibit at selected temperatures, when measured using a DMM's (digital multimeter) Ohmmeter function. ''Remember to disconnect the power from the oven when using an Ohmmeter.''
If the calibration doesn't work, try measuring the temperature probe at various known temperatures. You may need a separate oven thermometer to do this just in case the oven's temperature display is incorrect for what ever reason. Connect the Ohmmeter between terminal P29/1 and P29/2 on the control board.
If the temperature tests OK at the various temperatures, unfortunately the data sheet doesn't specify the resistance value of the bake element (part # 316563600). Usually they're in the range of 20-30 Ohms. (measure between P7 and P5 on the control board).
If you find the problem and it's a faulty part that needs replacing, here's the [https://www.searspartsdirect.com/model/5709fcnjp8-001428/frigidaire-fpef3081mfe-electric-range-parts|parts list] that is useful.
Locate the wanted part in the list and note the part number that is shown with it. Search online for the ''part number only'', to find suppliers that suit you best.
