Electrolux EKC6047X cooker.

Have a customer with an Electrolux EKC6047C cooker with the bottom main fan oven with the thermostat staying on all the time. This unit has the main switch on the front end of the spindle for light, fan oven, heating coil and the thermastat mounted on the end with T150-81380815 printed on the body.
Does this assembly come as one complete unit to purchace or does the thermostat engage on the end as a seperate unit?

The glass inner lower door had shattered from the heat?
They kindly replaced the glass free for the customer but not the faulty thermostat jamming on.
Not pulled this model apart before.
