GE electric range/oven is not reaching oven baking temperature setting. Baking element heats up red hot, but sensor/relay shuts off element before actual temperature can be reached. Digital indicator indicates that temperature has been achieve, whereas oven thermometers (several) show that real temperature is low by about 100F. Tried to adjust dial indicator +/-35C on oven controller, but did little to help. May just be the sensor probe, but would like input before proceeding to spend $80. Thanks,
