Have you used an Ohmmeter to check the resistance of the winding? Open or infinite Ω means the coil wire has become disconnected. A few tens to a hundred Ω means that the coil is still connected. Are both ends of the coil isolated from the iron core? If so, use the Ohmmeter to check to see if the coil is shorting to the core internally?
