Abstract
The invention relates to a method for carrying out maintenance work on structural parts located within the housing of a refrigerator, the refrigerator being divided into two parts separable from each other so that the interior chamber of the refrigerator becomes accessible. The method is carried out by opening the housing, carrying out the maintenance work, closing the housing and thereafter sweeping the housing with working gas. In order to avoid condensation in the cold areas of the interior chamber of the refrigerator after the housing is opened, the method provides that the areas of the refrigerator housing endangered by condensations be heated locally to a temperature, which is so selected, that up to and including the sweeping process following the maintenance work, the temperature does not fall below the dew point of condensable gases.
