Question about Zanussi ZEBF277W Bottom Freezer Refrigerator
When I open the door to my zanussi fridge freezer there is a bad smell. However i have clearedthe fridge out completley and the smell still remains. It is only apparent when the door has been closed for some time so I'm thinking that maybe it is something to do with a build up of gasses?
The defrost cycle is not happening like it should, that's what causes the block of ice (and poor air flow). If you have all that defrosted look at the defrost bi-metal, it usually is a small round disk with a couple wires coming out of it and it's clipped on the coils. When it's cold enough, it passes electricity to the heat elements, when it gets hot enough it "opens" and kills power to the heat elements. If that is bad (swollen cracked or bloated) and not passing electricity to the elements that's the problem. Another item would be the defrost timer itself, if it doesn't work (no clock motor turning) then it will never go into defrost. And the last and usually least expected failure would be the heat element themselves not working

How to check everything
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp .
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.
