Many of us have been horrified to find a much-needed block of ice that has shattered during the freezing process. The entire bottom of the block is covered with small fissure cracks.

This is a more common occurrence during the Spring and Fall of each year when we see larger fluctuations between the day and night temperatures. The condensing unit works more efficiently during the cooler evening temps and works harder during warmer days. Pressure is created in the ice when freezing different layers of ice under different operating conditions, thereby causing the block to crack.

As a temporary solution, Clinebell has suggested that you take a piece of cardboard about the size of the condensing unit, poke holes in it to allow for airflow and place up against the “fin” section of the condensing unit. This is creating less airflow through the unit causing a warming effect. Under extreme situations we have suggested that a fan cycle switch be installed inline. The switch causes the condensing unit to believe that the ambient temperature is warmer than it is, thereby creating a more consistent operating environment.

Since the end of year 2000, Clinebell has installed a fan cycle switch on all Carving Block machines that have been shipped with the condensing unit connected. The switch is adjusted for the conditions at the factory and may need further adjustment. A local commercial repairman will be able to make adjustments for local temperatures and conditions.
