Prepare suitable temporary chilled storage before disconnecting and emptying the appliance. The cleaning plan should protect the food as well as make the cabinet easier to reach.
What the observation tells you
Gather the approved cleaning materials and identify which fittings are removable first. Otherwise the food can sit out while you search for tools or instructions. Work in manageable stages where the manual permits, and avoid mixing raw-food containers with ready-to-eat items in the temporary storage.
A useful next step
Follow current food-safety guidance and the manufacturer's shutdown and restart process. Keep track of the time and storage conditions. Return food only when the appliance is ready for appropriate use; a clean cabinet is not automatically a cold cabinet.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
