The lights come on, and all seems to work, but no heat.

Bulb is separate to the theremostat.

hi amy, 
          it seems there is a defect in ur owen..because if light and fan works, it should heat, otherwise it means there is a fault in the heating element..so kindly cal any near by technician to sort out this problem or use our find oven repairman service to contact d near by repairman...

good luck

It sounds like the people who changed the elements did not connect them to the correct wires. The thermostat seems to have no effect on the elements, and the light switch seems to have no effect on the light, explain this to them and that you think they fitted the elements directly onto the power input to the device, instead of the correct connections.

since neither light is going on, then i believe that you either have a bad thermostat, or possibly that you only have half of the voltage going to it, and gaggenau doesn't have gas units so it doesn't have a glow bar like the previous guy said.

Hi,

If your electric oven is taking too long to heat or just not heating up right, then check out this tip that will give more detail about your problem.

Yes, it is most likely that the oven heating element has failed.

if the temp light or indicator light for the grill is on then i'm tempted to say that it is the element but checking for resistance is the only sure way to know..

If fan is working then the element has probably gone

Thermador SCD302 upper oven preheat does not work; the heat temperature goes up very slow.
