I have replaced more capacitors in appliances than electronics. The fact that appliances runs on higher voltages and stop/starts frequently exacerbate the heat problem. The 9 years old range hood in my kitchen is already had the start capacitor replaced twice. Whoever designed this unit decided to place the circuitry right in a hot spot, making sure that the capacitor will be gently toasted to death in a couple of years.
