Found something in a repair manual for RVs with regard to frig either
cooling to much or not enough.  Seems how effective the frig cools is
dependent on the actual position and insertion of the capillary tube which
is used for sensing the temperature of the cooling fins in the frig.  The
tube is supposed to be inserted into this clip and not laying along side or
suspended between fins.  Positioning is important.  Still learning about
this stuff but plan to take the frig out of the RV for some switch cleaning.
Lots of fun.  At any rate, this might help someone.
