not seen a lot of these yet , eng went out to this and it seems to be running ok with no loss of temp – but the alarm keeps going of , customer also has said no temp loss etc ..
ally, 3 beeps on a liebherr is door open alarm. 4 beeps means temperature problem.
how old is the appliance?
is the magnet in place to tell the appliance that the door is open or closed?
is the reed switch that the magnet interacts with ok?
