Fuses
If one of the main systems on the UCA SGSM (main power, fan, heater,
pump, and cooling solenoid) is not working, then you may need to check the
fuses.
1. Removing the top panel on the UCA SGSM and inspect the terminal block
which holds the fuses. They are labeled as follows:
2. If a fuse for a particular system is blown, a red LED light will come on
below the blown fuse’s housing.
3. Unplug the power cord leading to the UCA SGSM.
4. Depressing the tab on the bottom of the fuse housing should allow you to
flip the housing up.
5. Open the door on the side of the fuse housing.
6. Replace the blown fuse.
7. Close the door on the fuse housing and push the housing down back into
place.
8. Plug the power cord back into the UCA.
9. Check to ensure the system is working again.
