Diagnosing Non-Warranted Refrigeration Problems

Is your refrigerator or freezer not holding proper temperature?

Before making a service call that could turn out to be unnecessary and expensive, please be sure the following guidelines have been met:

1. Make sure the condenser is clean and not blocked by dust or dirt which WILL prevent a freezer or refrigerator from holding proper temperature. For example: If a refrigerator's holding temperature is a few degrees or more higher than a manufacturer's spec, there is a good chance that the condenser needs to be cleaned. Dirty condensers block the outside air needed to remove heat from the cabinet. Dirty condensers can also cause component failures. Be sure to clean every 4 to 6 weeks with a brush or vacuum!

2. Make sure the interior temperature control is NOT set to high which could cause the evaporator to freeze thus preventing the cabinet from pulling down to proper temperature. If the evaporator is frozen, unplug the unit overnight to thaw. Plug back in the unit in the morning.

3. Make sure the cabinet is level. Unleveled cabinets caused by uneven floors can prevent the doors from leveling and sealing properly thus allowing outside warm air inside the cabinet. Please call C&T if castor shims are necessary to level the cabinet.

4. Make sure product temperature is being checked which is normally 33° to 38°F inside a refrigerator, 41°F at the top of a prep table and minus 0° to -10°F in a freezer depending on the product load.

If these suggestions do not correct your temp issues, please call your nearest C&T Design location today.
