Oven Not Heating Properly

Replaced The Heating Element And Display Kit On 1/7/2009 Then The Heating Element Again 2/2/2012 However The Oven Bake Element Still Would Not Work Until I Calibrated It And Still It Would Not Reach 350. So I Focus My Attention On The Thermostat Sensor . I Checked It With And Analog Ohm Set At Its Lowest Setting It Read A Little Pass 100 Ohm Then With A Digital It Read 0.1 With It Set At 200 Or The Lowest Setting But If I Go Up To Setting 2k It Reads 1.078
