My Beneteau Oceanis
423 has a 12v frigoboat icebox
aircooled system and a CLD system with a large cold plate that works off the engine
or shorepower. On the latter the Johnson thermostat (mechanical) will cut off the compressor
when it reaches it's cold setting but will not turn it back on when the temperature rises. By turning the fridge off and back on again it starts working.
The thermostat is 12 yrs old I guess, as is the system. I believe the temperature differential has now widened with age. Any thoughts?
If this is the case I need to fit a new one. Electrically no problem but there is no easy access to mouse the new temperature probe into the fridge. The thermostat sits in a cupboard above the fridge, which seems fixed , having removed all screws.Clearly I need to make some opening in this cupboard floor to gain access and if so any advice?
