Fridgemaster fridge freezer has just stopped working, light comes on and can her some kind of motor at backi, any ideas???

Buy an inexpensive thermometer and put it in the freezer.

What is your problem?

Check for proper operation of the compressor motor which powers the cooling cycle. Make sure that the thermostat is sending electricity to the motor when called for and that the condenser fan is also operating. If motor is cold to the touch it has not been running - check the start capacitor if it has one and/or the start winding of motor.

don't seem like he is coming back. google the freezer model and put wire layout and you should find out how to wire it your self

no sufficient gas.

if you cant hear the motor/compressor running when energised then its likely to be a thermostat fault... but on energising the system if you hear a buzz then a click then its more seriously the main motor... turn off at mains for 5 mins then turn on... this should tell you either way

If there is no noise coming from it its poss thermostat or sensor and if compressor is stone cold. If compressor is very hot its sound like a gas or compressor problem.

Replace the evaporator fan motor.
