Hi, Bosch Fridge Freezer model KGU 3201. All panel lights

Resolved Question:

Hi, Bosch Fridge Freezer model KGU 3201. All panel lights flashing and interior light flashing in time with this, soft clicking noise in time with flashing from panel at the top. Occasionally the compressor tries to start but does not succeed. All still at right temperature as it only just happened.

What could this be, starter for compressor, compressor or control board. Its an old unit so I would fix it myself.

Hiya,
Unplug the appliance.

Take the cover for the electrics to the compressor off.
Unplug the compressor. (the unit plugs into the compressor, 3 pins so should just pull out).

Ensure it's insulated and not touching anything.

Plug the machine in.
Does the control still flash?

Thanks

Ok, disconnected the compressor and plugged back in. Now a soft buzzing but no lights at all!

Hiya,
OK, thanks for that.

Unplug, plug the compressor in again and plug in.

Thanks

Ok, now just the soft buzzing sound from the top near the light and no interior light inside and no panel lights.

Hiya,
OK, thanks for that.

All pointing to a faulty pcb I'm afraid.

Gain access to the pcb and see what you find.
Test for continuity between the plug top and the power connections to the board.
If ok, you're looking at a failed board.

Hope this helps
Let me know how it goes
Thanks
