Fridge freezer stopped making ice digital display has gone off at the front of appliance, when you open door lights flicker and it makes a noise.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

Call out the warranty supplier. Where is the noise coming from? If no warranty, check the electrics to the compressor and fan. sometimes the noise is the fan. Also switch off overnight and leave doors open. When restarting, if the noise has gone it will have been the internal fan hitting on ice buildup.

It sounds like the fan will need to be replaced.

There is probably an ice build up between the two sides of the appliance. There may also be a problem with the damper unit which controls the cold air coming from the freezer side to the fridge. The fridge is controlled by the freezer. Dependant on appliance. The door opens and closes letting the cold air go into the fridge and when the fridge is cold enough the door will close agin. This is not something that you will see happening it is normally concealed behing a diffuser.

Sounds like the unit is goosed and is trying none stop to get the temperature down in the fridge.

That is of course unless the ice is building up like an iceberg inside the cabinet in which case the thermostat has gone

Water frozen in the freezer supply line - you need to thaw out the freezer. About six hours, door open, turn freezer OFF. You'll need a cooler with dry ice for your frozen food. 99% certain it'll work after that.

Your fridge should be fine, if you have surges that frequently getting a whole house surge protection package would make alot of sense. Surges are especially damaging to electronic circuits found in TV's computers, cell phones, answering machines aell frankly in just about everything. Well worth the charge.

just about all friges work off the frezer .the evap fan moves the air fromthe frezer to the frig.so you would here fan noise.i dont know your brand but on most frezers if you turn the frezer temp to the highest setting thats acomplished by keeping the air from going to the frige.hence warmer frig temps .also make sure fan on out side back is working and condenser is clean.again turn air damper control from frezer to frige to lowest setting .somthimes this could be in frig section.God bless ,tom

Yes, I think you have a problem that can be fixed easily by a repair technician. The sound as you described it could have come from the air circulation fan in the freezer compartment striking ice. As the ice builds up it could have stopped the fan from rotating and air flow to the refrigerator compartment.

fully defrost it 48 hrs with the doors open and that can often cure it.
