Light bulb flickers and strange sound

disconnect the power and try to pry the prong in the socket of the light outwords,check the connection in the unit itself

Hello,

Very common issue on this unit, the control on the back is bad, the cam and riser will need to be replaced to fix the door.

Let me know,

I suspect the main control down by the compressor may be faulty. Without a model number I can't give you specific information, but these controls have a pretty high failure rate. The "knocking" you describe is likely the relay(s) chattering. The board controls every function on the refrigerator, including the turning on of the lights. Have someone screw the bulb in while you are behind the refrig listening down by the compressor area. The control is mounted to the LH side of the compressor in a plastic case.

You have a bad electronic control board . This part is mounted on the back of the refrig , at the lower left corner , inside a plastic holder . The part number is W10135090 . It costs about $ 100.00 . This board , also controls the 2 control knob lighting .

replace the main control board lower left rear side of unit part #4334000 from appliance parts pros 1-877-477-7278

Short in the wiring harness.

I would try replacing the bottom door cam assembly. I have also seen the actual cabinet making a popping noise during opening which is there is no cure for that.

check the door switch to see if its working. also check the bulb it may be loose in the socket.

Your bulb is shorted out internally. Try another bulb. Please post as as helpful if so.TY

sounds like you have an issue withthe electronic control board locates behind refrig next to the compresssor, in a white housing
