Thanks so much Jake.
So if we need the cover - it looks like the appliance parts online store you referred to has the cover too:
WHIRLPOOL 2162358 Cover, AP3064545 | AppliancePartsPros.com
Does that look correct for our model?
But in terms of the start relay vs the overload - do you typically need to replace both? The start relay is the one is really rattling (with black particles falling out). The other one (overload) rattles a little - does that also indicate it needs to be replaced? We didn't know if failures on that are just as common as the start relay and its just best to replace both at the same time.
Jake - WE are having similar problems with our KitchenAid KSRS25IHSS02. Over the weekend, it stopped cooling on both the fridge and freezer side. Lights still worked, sounded like it was still running, but went totally warm. Now this morning it is cooling again, making ice and getting cold on both sides. Not sure what to do, and whether to trust it by reloading it with food? Should we go ahead and try to take off the back cover and look around? Or let it go and wait to see if it happens again? Maybe order a part just to have in case? Any advice is appreciated.
