St George wall oven element. which wire to connect

Clean grease off the fan blades, remove the fan motor and re-secure it. Make sure there are no blades missing from the fan. Lubricate the fan shaft. Make sure any guard on the fan is not fouling and make sure the guard is properly secured. Vibration is what is likely causing the noise.

Or just replace the fan parts.

since I have no model or serial, I assume this is an electric oven based on the description provided. this is usually an indication that the heating element has gone bad. possibly having a short to ground which completes a partial circuit in turn giving you heat and a light. I would look in this direction first.

Best to get help.
It may require terminations

check the elements and the oven safety valve? and check for separate fuse to oven?

Can't find your model # but maybe this can help:

I have a St George glass cooktop with temperature sensor light.It takes forever for the light to go out when I use the main element and that section often feels like it is still heatinglong after it has been turned off.Can there be power leakage through the switch for the main element

if digital the replace the oven control / if dial then the dial is at fault . mm

check wiring to cavity air pressure switch terminals eg the two wires should be connected to common(c) and Normally open (NO)

Anyway that will get you to the right people.

Depending on model-
Put the door at an opening of about 100mm. You should feel an indent for thecorect position.
You will probably need 2 people, 1 each side,
Slide the door upward at an angle same as hinge, It will slide off the hinge.

If the hinge is broken, and they usually break inside the wall of the oven, it will be very difficult to slide it off the broken hinge.
