Jane I purchased this part, #00436632 heating element, on the basis of my description of the problem I had with my Bosch oven, Model # HEI7052U. Since then I have found that the problem is not confined to the convection bake setting. n both the convection bake and regular bake settings the oven preheats properly but often fails to go back on after preheating. If I turn the oven off and on again, the preheat cycle is reactivated showing a temperature much lower than the set baking temperature. The broiler seems to be too hot, too, but I don't have any way to measure it. Is installing the part I purchased the right way to fix this problem?
Answer Hello Jane. No, it sounds like either the sensor or the board is bad on the unit. The sensor should read around 1100 ohms at room temp and 350° it should read around 1650 ohms. If it is good, replace the board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
