Noisy Slides? At least yours work!! On 2015 Big Horn 3875FB, bought in late March my slides would not come in recently. After playing with it finally got them closed. The living room/kitchen slides were the worst. Sometime the fridge slide goes first and then the other second and then they will go at the same time? Does anyone know the correct order. I talked to Jamie in customer service at Heartland and he thought might be the batteries are weak? All had about 13.25volts but thats is not load tested. Any advice or ideas or knowledge is appreciated. Do I need to go to Lippert? My dealer is 350 miles away and do not trust or like them. Dave
Hi DaveTyler,
If the slides are operated with a single switch, the one with the least resistance moves first, and the one with the next least resistance, until all are in. Same thing going out. Usually they follow the same order repeatedly, but if the resistance is about the same I suppose the order could vary.
If your issue is that they move a little, then stop, then move, then stop, you probably have a weak 12V DC mini-circuit breaker. I've attached a couple of pictures. The breakers are on a buss bar near the battery. Breakers cost $5-10 and can usually be found at RV Parts Dep'ts, auto parts stores and marine parts stores. You'll want a 50 amp auto-reset in the same form-factor as the original.
Btw, if you're reading 13.25 V on the batteries, you're probably reading the output of the Power Converter. If you shut off the 110V circuit breaker (in the main breaker panel inside the coach) for the Power Converter, you'll get a true reading on the battery voltage level. Low battery voltage/bad battery cell can also be responsible, along with loose wires, corroded terminals, and loose grounds.
