After a lot of research on internet we thought it might be the condenser fan motor . we were a but confused as frig still working and cooling. I had imagined if motor gone bad it would just stop . However on taking back off frig we could see fan sometimes slowed and then began loud "animal " squeaking noise ! Although the back bottom of our fridge was relatively open it was very tricky to ease out fan and motor. Fortunately I had also ordered fan and grommet as fan was almost impossible to remove and had to be pretty forcefully bent and grommet was disintegrating as was very brittle. They had to be removed to put new motor in the holding brace. It was still quite awkward to wriggle new fan and motor back in . However frig has now stopped squeaking and touch wood is working fine ! Fridge is about 14 years old . We did go to look for a new frig in case we couldn't fix the problem but annoyingly shelf etc " improvements " have been designed which aren't what we want . Parts were sent very fast and exactly right fit . second repair made using your company . Thank you very much .
