I have an Electrolux EI23BC30KS4A freezer that's from circa 2015, and there's something that sounds like a relay clicking about every 5-30 seconds underneath the freezer behind the vent grate. The fridge has a high temp alarm that's not coming on, and if the fridge warms up a bit (i.e., the door is open to access the fridge for a little while) it stops clicking for a little while, but it seems like it's getting closer together.
I looked at the alleged wiring diagram here: https://c.searspartsdirect.com/lis_png/PLDM/R1601038-00008.png
and it seems (unless I'm missing something) that ALL of the relays are on the board and cannot be individually replaced via plug-and-play harnesses like a car.
Am I pretty much stuck replacing the whole board?
My instincts, since everything seems down-to-temperature, is that it's the coil heater relay that's crapping out, thoughts on that?
