PNC 928405947-02
Strange fault – temperature keeps fluctuating and the door open bleeper is going off intermittently even when noone is near the unit!
I am going for the control board although a little nervously!
Any thoughts greatfuly received. 😀
Re: zanussi fridge freezer ZX99551
before you scap the board
check all capacitors for signs of the top bulging
try changing the power supply cap
from the picture i have connectors towards you look right hand side grey oblong block looks like a 1uf these go down with age
if it is that simple cheap fix
look in simple pcb repair tips above and you will see piture of other fridge boards with similar probs
hope it helps
DaveRe: zanussi fridge freezer ZX99551
before u do that check the following…these fridges can be complex!
defrost heaters > may have 2 !
fan is running
evaporater is not blocked wih ice
if temps all over the place the ntc sensors can be badly out of calibration
remove plinths and clean condensor as it sits underneath fridge
check compressor temp and make sure compressor cooling fan is ok
hope this helps, chrisRe: zanussi fridge freezer ZX99551

Thanks again 😀
