fitted new grill element to neff B1476N2 GB/02 which has a relay and sensor slid into its housing,the sensor i take it is the stat which goes back to pcb, the problem i now have is that as soon as u switch on all that comes on is the cooling fan , when i take the sensor out of the element the oven comes on fine but no control over heat first time ive come across one of these, the element cost a arm and leg direct from bosch which was the only place i could get one quick and the sensor is near on £50 if that is the problem could anyone confirm that they have had this fault to many thanks andy.
