If you plug in the part or open or tear or unseal the plastic or shrink wrap on an electrical or electronic part you CAN NOT return the part for any reason. Instead of using proper diagnostic procedures, some people resort to trial-and-error parts swapping when they don’t know how to fix an electrical problem. When parts they have installed do not fix their problem, they want to return them and try something else. Electrical parts are easily damaged by improper installation or testing therefore we can not accept returns on these items unless they are NOT plunged-in, opened or unsealed.
