Expert Reply:

If the latch on your Atwood surge brake actuator, like part # DM72VR, is fixed in any position start off by using some lubricant like WD-40, PB Blaster, or UltraLube Biobased Spray Lubricant and let it sit for a while. You may have to do this a number of times before it loosens up. Hitting it with a rubber mallet after the lubricant has time to work could help as well.

Once it breaks free you should apply some more and work it in a little more.

If the latch system itself is damaged and beyond repair then you may want to replace your surge brake actuator. We do have repair kits like the Curt # C25194 but there is no guarantee that it will be compatible with your current system.
