It can. A rusty or corroded thermistor or connection can give the board wrong temperature readings, which makes the fridge cool poorly, run nonstop, or throw a fault. The 618548 has been discontinued, but its replacement, the 636658/ 621742/ 50665, is in stock. If the fridge still isn't cooling after that, see our guide on RV refrigerator not cooling.
