Freezer too warm(everything melted), refrigerator too warm

Using socket wrench, took bottom right panel off on back side of refrigerator to expose compressor. It was very hot to touch, with no noise, signifying it wasn't working. It was a Tecumseh, TP142ar229b8. Evidently from internet search this is not a good brand. Turned off power at circuit box. Removed metal spring clip holding on white relay. Took off capacitor (black square piece) attached to relay. It was okay as I measured 15uF with multimeter. Disconnected electric cables to white relay by pulling off connector. Took off white relay with long cylindrical protrusion from compressor by pulling it straight off. Shook relay - pieces of ceramic fell out, indicating it was bad. Ordered and received new one (next day). Attached new relay to existing compressor by pushing it on. Replaced capacitor and electrical cables by pushing on. Replaced spring clip. Turned on power and compressor was working. Replaced bottom back panel.
