Hi, My daewoo frs-U20iAi fridge freezer fan in the fridge side makes an annoying noise when doors closed. No obvious ice build up or other problems. Any ideas?

worthwhile checking closer. noisy fan can be due to fan blade hitting ice if there has been a build-up. otherwise needs replacing

its a heater cycle problem..the defroster is not working properly. its building up ice in the evaporator that touches the evaporator fan that makes that loud noise but stops when you open a door. it could be either a bad heater, a bad thermo disc or a bad timer.hope i was able to help

The problem is a buildup of ice on the plastic housing (the curved plastic bit) in the back of the freezer under the fixed shelf where the icetub goes. The fan behind this plastic housing is hitting the ice when the defrost comes on.

Unplug the fridge, unpack the freezer, remove the four screws in the back, take off the sheetmetal backing and let the fridge thaw. You can remove the plastic piece after a while and get the ice off (be careful not to remove the styrofoam insulation by going too quickly).

Reassemble and you're back in business, for a few months. I'm never buying Samsung again myself.

MIne has the same problem, the insulation is breaking down and cannot be repaired.

try to re insert the ribbon connector on your PCB board possible loose connection then reset your unit to unplug your unit for a few minutes the n plug on after then observe the operation.

Testimonial: "Thankyou. I tried that with all the connectors, with no joy. Tonight the control panel light kept coming on for no reason. ??"
