Hi
Must admit never heard of Montpellier, however this is the make of frost free fridge/freezer at my mothers.
Freezer is operating at -27 degrees C , but fridge is sitting at 13 degrees, unit seems to be running most of the time, I suspect it’s only pausing during the defrost cycle.
Fridge door seal seems intact, there is definately a pull when you try to open the door, so I suspect it’s air tight.
My guess therefore is a faulty fan that should blow cold air up to the fridge but will bow to others better knowledge on such matters.
As far as I can tell the thermostat in the fridge only sets the fridge temperature , there doesn’t seem to be a user settable control for the freezer temperature.
Other than the user manual not finding any documentation (service/repair manual related) or a great amount of spare parts.
Any suggestions welcome as to how to remedy.
Thanks
Jeremy
