Yes they have an internal fuse on control board for power supply.
Unfortunately you have to disassemble to access.
Then if blown you have to ask yourself WHY :H
If you access it and replace fuse...plug in and test run before reinstalling.
If fuse blows again......get a new replacement.
Just measure current one......go to Walmart/Costco/SAMs etc and buy new
