Model BR16.3A, an integrated larder fridge.
Yesterday food was frozen inside. Temp control turned up, it was on the normal setting before. Fridge warmed up then refused to cool down again, no noise from inside. Left on all night with temp control at coldest setting, now frozen again. Temp control turned to normal working position and warming up, but no response when the temp control is changed. Is the thermostat on the way out please?
