The great tutorial. You could also use a 9-volt battery to test the relay by connecting the two pins to hear the click, and use a multimeter to test the resistance between the two pins. The coil resistance should be 360 Ohms. You can download the data sheet from Mouser Electronics
Sometimes 9 volts isn’t enough. It depends on the coil voltage. Test with a battery is for relays not on the board. You could damage other components on the board. I actually have the data sheet. Thanks for the feedback
Yes a relay is a switch. What it is activated it closes the circuit. Keeps in mind the board sends low voltage dc to activate the relay. The magnet closes the relay without the dc voltage. So sometimes the board is not supplying the necessary voltage to power the relay. Hopefully that helps

@@appliancerepairshorts Thanks for the tip.
Maybe Im not understanding the magnet. Im getting the same error codes and numbers on my meter am I supposed to hear something click with the relay?

How strong does the magnet have to be?
Pretty strong, enough to engage the contacts in the relay
