Hello, can anybody help with the below problem, I have been trying now for 2 weeks but to no avail.

When I open the door to the fridge compartment of the fridge freezer the internal light starts to flash on and off also there is a clicking noise that keeps time with the flashing light. This only occurs when the motor is running. After a short time the light remains on, the motor cut out and fan stops. I close the fridge door and after a while the motor starts and stops normally. Both fridge and freezer appear to be working normally. The clicking sound seams be be coming from the area where the control PCB is located. I have tried the following to resolve the problem.
1 Turned the unit off for 24 hours and back on but still no good
2.Replaced the bulb for LED type but still no good
3.Removed the bulb but now only get the clicking
4.Checked the control PCB located to the front of the unit, no sign of burning or burnt components and no loose connections

Any help welcomed

Thanks

Stewart
