Lennox CB29M-21 Air Pressure Switch
The reason for the existence of the switch is to figure out if the primary air circulator is actually running. The majority of pressure switches may have a manual reset, which means it will have to be manually reset before the system will continue its normal operation. This pressure switch is one of the key safety creations designed to stop injuries or explosions.
Signs of a Failing Pressure Switch
- Your heating and cooling system can not operate.
- The set temperature in the house is rarely fully attained.
- Wrong volt range running through the switch.
