Is it fairly easy to replace pump relay switch?

[Frankw1]

So my filter pump has recently begun to remain running when its program has ended. Put in service mode, turn pump off, pump remains running. Tap the pump relay switch and the pump shuts off. I can see that the pin on the relay is getting stuck. Getting more and more random and the forums here suggest the relay is probably going bad.

My question: I'm fairly handy and have done some repairs to the system myself, but want to know if replacing the pump relay is something I should be able to do myself. I can usually find a reliable video on Youtube for anything I need to do, but there are none that detail the process - only ones that show how to troubleshoot. Does anyone have a good source for a video or written instructions? Or is this something that should only be done by a qualified pool tech and not something I should attempt myself?

It's pretty easy. Turn off all power, remove the wires from the relay, remove one of the screws at the base of the relay, loosen the other screw, remove the relay, install the new relay, tighten both screws, reinstall the wires like they were.

If you have an unused relay, you can use that as a replacement or you can get a new relay.

If you take an unused relay, tape off the small coil wires so that they don't touch anything. They should not be powered if the relay is not being used, but it's safer to cover each with a small piece of electrical tape.

Post some pictures if you need more help.

The two top screws are where the small wires from the control board connect. They supply 24 volts dc to close the relay.

The bottom 4 terminals are where the power wires connect.

You can see the base has two slots where the screws hold it in place.

Mark the wires and take pictures before removing the wires so that you can put them back correctly.
