Sharp SJ-F624ST 4 door fridge/freezer. Moved house . When switched on "door open alarm " sounds continuous. fridge / freezer not working . all doors close fully. What could be the problem ?

Question edited for clarity, and add maker.

It may need a top up of refrigerant gas, but first check that the circulation fan in the fridge is working. Also make sure the condenser coils are clean.

Hi,

please increase the temperature in the fridge portion of your fridge as it sounds like you've set that compartments temperature too low.

Thank you.

Open Freezer Door Press Door Switch and checked Freezer Fan is working or not.
If fan is working then problem in Ref compartment. If not working then replaced Fan.
In Ref Compartment checked all duct clod air is coming or not.
If not coming then Damper is defective.

Disconnect the door switch, this will stop alarm but light won't work

Checked Damper in Ref its working or not. You can checked open Ref door press Door Switch and hold your hand near chiller tray Duct

The part number you need is going to be WR09X10050. This is for the damper assembly, but while you are at it change out part number WR55X10150. this is the part that controls the damper and more than likely if one fails the other will be soon to follow

it sounds like either a defrost problem or damper door problem it is very well worth fixxing

sounds like when you moved it you created an air lock, when moving fridges etc. should always leave for 24 hrs to settle before plugging in.... , no guarantee but try laying it down and leaving overnight then stand it up again and leave for at least 24 hrs for the refrigerant to try and sort itself out. UNPLUGGED from mains of course... good luck
