Jane October 22, 2013 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?
1 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...
