Pentair Air Flow Switch

Pentair/Sta-Rite 42001-0061S Air Flow Switch

Pool heaters are pretty complex appliances, and ones that operate under very demanding conditions. Weather, moisture, harsh pool chemicals, heat and waterflow all cause damage over time, and after a few seasons of use, every pool heater will need maintenance or service to keep functioning as you need it to.

Air flow is essential to ensure that your heater functions safely, and when the air flow switch in your Pentair or Sta-Rite heater needs to be replaced, your heater may not function at all.
