Description
The A.O. Smith 9004634215 Pressure Switch Kit is an essential part of the HVAC systems especially the gas water heater. It comprises all the components required to replace a defective pressure switch. It tends to control air pressure on the combustion chamber. If the airflow is low and inadequate for combustion, the switch does not allow the gas valve to open, which means no dangerous accumulation of gas. This increases safety, sustains the proper water heating and avoids possible harm on the water heater. This kit helps to replace a worn pressure switch and get the water heater working correctly and last longer.
