A spring returns components. Relay failures are common. The internal coil burns out. Contacts become pitted often. This stops proper power flow. You might hear clicking. The appliance still fails. Intermittent power suggests relays. Heat affects relay function. A relay sticks open sometimes. It causes no operation. Other times it sticks closed. This causes constant activity. Relays are vital components.
Simple Diagnostic Steps and Tools
