Where is the defrost termination stat located on the evaporator?

The defrost termination thermostat is strategically located in the U bends of the evaporator coil. This placement is critical because it enables the thermostat to accurately monitor the temperature of the evaporator coil during defrost cycles. The U bends are typically the area most prone to ice accumulation due to the design of the coil, where moisture can readily collect and freeze.

By being positioned in this area, the defrost termination stat can effectively sense when the evaporator coil has reached the desired temperature, signaling that the defrost cycle should end. This ensures that the system operates efficiently and prevents unnecessary energy consumption or potential damage from prolonged defrost cycles. Hence, the location of the defrost termination thermostat is key to maintaining optimal performance and preventing issues related to ice buildup.
