There are four simple steps to try initially:
1) Clean up the seized fastener... if the photo with this question is anything to go by this will take a while :-)
2) Use a penetrating lubricant liberally. Use brushes to work it in, further cleansing the area.
3) Rock the fastener in both directions... particularly effective if it starts to come undone then jams. Add more lube as you go...
4) Try a freeze and release spray... very effective and much safer than heat around delicate electrics.
