Welcome to iRV2.

Is your slide a push button ; one touch operation ; or a hold the rocker switch to extend or retract type?
Do you have a manual that states that 15amp is the correct fuse size?

If it's a push button type, and your fuse size is correct, then somewhere there will be an electronic controller for the slide motor , that should shut the motor down before the load increases, at the slide stops, and blows the fuse.
Here's a picture of a common controller, so you'll know what to look for.
They can be located anywhere, in my current coach , it's on the opposite wall from the slide , under the kitchen counter, last 5er, it was on the floor , under a drawer, and I've heard of them being found in basements. There is an adjustment on this one.

Definitely sounds like a bad controller.

I keep thinking that our POWERGEAR wiring is protected with something larger than 15amp, but no matter and if that has been serving you thus far, then something else is amiss. For instance and with the way our slide sounds, at the end of travel, I'm most sure the control board has a current limiting device for saving things.
Now if yours has this and it's now malfunctioning, then that would account for this high current situation caused by this huge increase in torque and just like any other motor with a locked rotor.

I have a Power gear document , that I down-loaded from their web site, while helping a friend with his slide, on a 2000 5th wheel. Appears to cover all their systems. The file is too large to post here. 111 pages.
If you can't find the info on the, Power Gear web site , and would like a copy of the file , PM your e mail address to me and I'll forward it to you.


EDIT: Forgot that you are new to the forums. To send me a PM ( personal message) click on my user name in the top left corner , and select the personal message option, only I will have access to your address.

Ken, are you using slow-blow fuses?

My slides have a 30A fuse on the main 12V panel and we replaced it with a circuit breaker type after blowing it a couple of fuses, that was 12 years ago, no problem since! I think we were new to it and held the switch too long.

Slide blowing fuses

Problem solved !!! After much looking and frustration it was found that a so called tech, that was checking for a generator problem, had changed the 30a fuse with a 15a..... Why, who knows, I only found it due to lack of documentation by confirming the actual circuit component values on the printed circuit boards.. A Big Thank You to All that sent me comments and info...ken.
