The 12V Power for your fridge comes from the DC distribution center.....fused
The 12V power for your slide out comes directly from your battery.
Check at battery for power wire to slide out and see if it has an in-line fuse that is blown OR a automotive type circuit breaker (looks like a small box with wires on two studs)...see if it has a small reset button on side.
Is it time for your medication or mine?
