Frequency of breakage

How often should these break. We have recently had three in two months (Five in four years). I am not overtightening so does this indicate a problem with the glass or the oven itself.

    Re Keith Harris: The usual cause of failure is expansion due to heat, are you using a 'self clean or pyro clean' function as these can produce very high temperatures (400c) to incinerate the deposits?.

  • We too are suffering frequent breaks. Always the threads coming away from the bowl of the cover. Have tried fitting really loosely but same happens. Could it be a design/ manufacturing fault? Perhaps of this batch? Definitely not fit for purpose. The lamp is in the grill by the way. By Keith HARRIS - Cornwall - 10 January 2017

    If the cover is tightened when the oven heats the glass expands causing pressure on its surround. Only screw up loosely to prevent this re occuring.
