Delonghi oven grill broken, oven still works?

Have you checked if the heating element is getting hot ? Fair chance you need a new one.

have an electrician replace the failed elements

I would have a electrician look at the breaker switch as being in need of replacement. They do weaken over time and cannot handle the load that they were designed to carry when brand new.

always turn the power off first , you will need a flash light look carefully around the bottom element , I think it has burned out on you , it will have a bump or burned spot on it or may even be broken off , this is bery easy to replace and cheep if you find it is burned or broken off email all info on oven make, model, serial number I will locate the part and tell you how to replace it Have a nice day !

Google delonghi d906gwf electric oven lists Manual.

If you have a warrantee I'd take it back and get another one. First time use should work.

Ok get a Service Manual, and the Sensor, and it is not too hard.

That's where I found it. Not easy to find though.

If you need to go direct to the espares website you'll have to hunt around a bit. But try looking out for a small Adobe link on the left hand side when in the ESM465 area.

Hope that helps.
