  If your Delfield Refrigerator's condensing unit runs for long periods, several factors could be the reason. An excessive amount of warm product placed in the cabinet may require additional cooling time. Prolonged door openings or doors left ajar can also cause this issue, so ensure doors are closed when not in use and avoid keeping them open for extended periods. Check the door gaskets to confirm they are sealing properly; adjust the door or replace the gasket if needed. A dirty condenser coil can also contribute to this problem, so clean the coil. Finally, an iced-over evaporator coil could be the culprit; turn the unit off and allow the coil to defrost, and make sure the thermostat is not set too cold, also check the gasket condition.

  If the cabinet temperature of your Delfield Refrigerator is too high, it could be due to several reasons. First, check if the thermostat is set too high and adjust it to a lower temperature. Ensure proper air circulation within the cabinet by re-arranging the product. An excessive amount of warm product placed inside may also cause this issue, so allow adequate time for the product to cool down. Avoid prolonged door openings or doors left ajar. A dirty condenser coil can also contribute to the problem, so clean it. Lastly, an iced-over evaporator coil could be the cause; turn off the unit and allow the coil to defrost, ensuring the thermostat isn't set too cold and checking the gasket condition.

  If your Delfield Refrigerator cabinet is not running, there are several potential causes. A blown fuse or tripped circuit breaker could be the issue; replace the fuse or reset the circuit breaker. Ensure the power cord is plugged in. Check that the thermostat isn't set too high and lower the temperature setting if needed. Verify that the system is turned on. Also, the refrigerator might be in defrost cycle, in that case wait for it to finish.

  If your Delfield Refrigerator is freezing product, the thermostat might be set too low; adjust it to a higher temperature. A dirty condenser coil can also cause this issue, so clean the coil. Also, ensure there is enough cabinet clearance for proper refrigeration system operation; adjust the cabinet's position to gain adequate clearance.
