Combo fuse box and converter

Yesterday I unplugged the 30 amp plug and removed the cover of the electrical converter. Wow, there was a lot of dust and dirt in it. It has a fan motor to help cool the transformer. The blade was full of dirt. I vaccumed out the area, then used a paint brush to remove the hard to reach areas. I figure if it is clean, it will work more efficiently. I suggest that it is something that you shoulk check.
