The model # EP1015
How do I tell what function it performs. I know not so much about circuit boards almost believe morse code haha

LOL,
Or he thinks it's is 2nd life as a metronome.

We need to find the service manual or the schematics.
You should tell us the part number identifier of the relay on the board.
It's one of three relays it's very hard for me to tell any ideas I found a service manual on the web I will try and post the link soon
Here is the link for the service manual

Looks like there is absolute minimal info on any control board info that they are wanting you to know in that literature..
But, in looking at the mechanical aspects of its manner of construction, there are absolutely
multi mechanical aspects, able to make noises akin to that of a relay.
If you have tracked it down to a relay, a fingertip sequentially resting atop of each will tell you a lot,
as being compared to ones depending upon aural source differentiation.

If I were a betting man I would say it's the smaller one by itself RY503
No need to bet.
Put your finger on the black plastic casing (without touching any thing else) ,
you will feel the clicking one very clearly.
Before you removed it, i would simply place my finger on top of each relay until i felt the clicking
Check fet502 and the other transistor (see if you get any shorts)
Maybe, can't tell from the picture but there looks like a bridge rectifier next to the fet502 ? If so check that as well, when powered up you will see AC one side and DC the other, make sure that's working..

Ok I did that it is ry503
What color is the rectifier and please explain how to test it. And which one is fe502 and how to test
Here are a few pics of the other side of the pcb. What does the D502 Q502 and R502 signify
Sorry I don't know much about circuit boards and components but I am willing to learn. Still need help I appreciate all the help to this point
Presuming the relays are DC operated, I look first for the usual diode placed across the coil, it is usually adjacent to the relay, a meter across the diode when the relay is activated will sometimes tell if it is a low voltage problem, or the device operating the relay is turning on/off, relays click or chatter because one of these two reasons.
They show as 5v DC type.
A place to start.

Minder here is a picture of the board in question can you please point out which one is a diode
