Spent three hours on a fridge that just needed a new start relay

Got a call for a Whirlpool fridge not cooling in a house over in the West End. I was sure it was a sealed system issue because the compressor was humming but not starting. I checked the overload, tested the windings, even pulled the unit out to check for a restriction. After three hours of going in circles, I swapped the start relay on a hunch. It kicked right on. I felt pretty silly. Has anyone else had a simple part trick you into a long diagnostic chase?

Three hours on a Whirlpool in the West End is brutal.

Three hours is a long time to be stuck on any bus, but that route is a special kind of slow. It stops every other block and the traffic over there is always a mess. You'd probably get there faster by walking after a certain point. Makes you wonder why they don't just add more buses during the busy times.

Ugh, my back hurts just thinking about that.

Starting a diagnostic on every fridge by swapping the cheapest part first is how you end up replacing perfectly good relays and capacitors for years without learning anything. Three hours of methodical troubleshooting that ruled out the sealed system, the windings, and the overload is time well spent. You know with certainty now that compressor is solid and the start relay was the only weak link. That kind of confidence is worth more than the twenty minutes you would have saved by guessing.
