Bush combi fridge. BFFF48144B how do i change the light bulb? Read all instructions but it doesn't budge.

normal if it is the outside surface that is warm
as that is the condenser exchanging the heat through a panel
the compressor will run for a period until the heat inside the compartment is brought down
Experience has proved that to get any fridge /freezer to work well , place a bowel of water in first as that gives a heat source to cool down and it will do so more quickly that just an empty volume

I believe that a short circuit creates a defective light bulb inside the refrigerator or some other element in its circuit (door switch, lamp socket, wiring).

Good day James.

There must be a loose cable for the green light to come on. Your thermostat might need replacement especially if doesn't go on defost which happens automatically.

Make sure you use the same type of bulb for the replacement or you can run into more problems. Use same amp and volt and watt.

Order parts online through freezer parts supplier.

If you have laid it down when you moved it you need to have it in the upright position for 24 hrs. before plugging it in. (so unplug it. let it sit for 24 hrs. then plug it in.)

Make sure light bulb is screwed in pretty snug

this is definitely not normal. It had to be caused by either a bulb of higher than 40 watts, or a situation where lots of items in the fridge were closely surrounding the bulb causing it to overheat.

check the adaptive deffrost control inside of the refrigerator compartment, more than likely thats bad.

Check the vents of your fridge side if present, if no air then may be your blower not working or some ice formation that blocks the air(try defrosting). Check also your vents for obstruction or overloaded with stocks.
