@westlake.kitchen: How to check the evaporator temp and start defrosting. A single click on the DOWN button (with a snowflake) will display the evaporator temperature. Normally, the evaporator temp should be only 10 to 15 degrees lower than the current temp. For example, if the current temp is 0°F, the evaporator temp should be -10°F to -15°F. If it's -20°F or much lower, like -40°F, the freezer needs defrosting. #repair #commercialrefrigerator #commercialfreezer #commercialrefrigeration #kitchenequipment #restaurantequipment
