Large slideout blows fuse

[Monty-Rob]

I have a 2014 Lifestyle.
Before Evergreen closed their doors I got a new relay board for the large slideout from Dexter Axle. The slide now runs smoothly. Basically cut 50 feet of wiring to 8.
Bottom line is that after 4 to 5 times of using the slide the small 20amp fuse blows that is located in the front basement.
By the slide motor is a 25amp slow burn fuse.
20 amp Fuse always seems to blow after slide is in and I try to extend it.
I have a call in to the manufacturer (Dexter) but am open to any of your thoughts.

Thanks in advance...Rob

While you are lubricating those slides don't forget to put some "Slide Out Rubber Seal Conditioner" on the seals. It works magic reducing the drag of the seals when the slides are moving.

Are you saying it only blows the fuse since you changed the board and wiring? If so there is something wrong with the new wiring. If the new was an attempt to fix the problem and didn't work then you need to check and see if the fuse is correct. Two fuses of different sizes in the same circuit doesn't make sense.

Thanks for suggestions...Rob

Check the wiring to the slide drive motor, check for bare wires, "kinked" wiring, cracked wire insulation,melted wiring, connections at motor and any junction boxes. Wiring maybe getting "crimped" or connections are loose and maybe contacting a ground, when the slide is moving inwards causing a short which blowing the fuse.

Check the tag on the motor to see what full load amperage draw is and fuse accordingly. The slide may be blowing fuses due to lack of lubrication. I like dry Dupont Teflon lube . I spray it on all mechanical parts plus slide seals and the underside of our slide. It slides very smoothly. Use a slow blow fuse and not fast acting.

If one fuse is 25 amp slow blow the other needs to be at least the same. I would replace that 20 amp fuse. 🙂

I had a Keystone Cougar X-Lite TT that did that on day #1. CW adjusted the mechanism to minimize the draw to no avail. I eventually discovered that the wall switch was defective and would not turn off after I let go of the button. New switch & all was good. Not saying that's what your problem is, but something to think about.
