A Lennox 68W55 Sampling Tube supports accurate airflow sensing for dependable control response within the equipment.
The sampling tube directs airflow samples to the detection assembly so the heating and cooling unit can monitor duct conditions accurately and respond appropriately. Its 24-inch metal construction matters because the rigid length and durable material support proper placement, consistent sampling and reliable performance within the HVAC system.
The sampling tube may need to be replaced if the heating and cooling equipment shows unreliable airflow sampling, nuisance alarms or delayed response from the monitoring components. Physical signs can include bending, corrosion, blockage or loose mounting and environmental signs may include dust buildup, moisture exposure or debris that could interfere with proper operation.
