Frequently asked questions
How do I know the board has failed?
Typical symptoms are a dead display, relays that will not latch, erratic scheduling, or a system that resets on its own. Before replacing a board, rule out the transformer, the incoming supply voltage and any blown fuses, since those faults present the same way.
What is the part number for this control board?
Pentair lists this control board under part number 461105. Quote 461105 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Do I need the exact revision of this board?
Yes. Boards in the same family are often not interchangeable across revisions because the firmware, connector layout and relay count change. Match the number printed on your existing board rather than the model name on the equipment housing.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Should an electrician install this?
Replacing a control board means working inside an energised enclosure. Cut power at the breaker first, and if you are not comfortable identifying line and load connections, have a pool professional or electrician do the swap.
Is there a warranty on this control board?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
