Maintenance and Service of your Thermo Refrigerator
All laboratory refrigerators feature automatic defrosting and, in normal conditions, means
that no manual defrosting is required. However, in certain conditions (e.g. when the
refrigerator is very full or when any new items of are stored in the refrigerator) frost may
form on the rear wall of the equipment as the compressor must run for long periods of time.
As automatic defrosting takes place while the compressor is not running the refrigerator may
not defrost completely before the compressor restarts. In these instances some manual
defrosting may be required.
Before manually defrosting the cabinet, make sure the power lead is disconnected from the
mains. Any loose frost found on the evaporator can be removed carefully using a wooden or
plastic scrapper.
WARNING: Do not use any knives or sharp metallic objects to remove frost.
Alternatively a non-scheduled defrost can sometimes be carried out as follows:
