RV Electrical Repair in Denver, CO

RV Electrical Repair in Denver, Colorado — 12V, Shore Power, Solar & More

Denver's elevation and temperature swings create a uniquely challenging environment for RV electrical systems. Cold nights at 5,280 feet drain AGM and lead-acid house batteries much faster than the same coach would experience in a mild climate. Meanwhile, summer UV and heat accelerate insulation brittleness on wiring runs, and campground power pedestals at locations like Dakota Ridge RV Park and Cherry Creek State Park Campground sometimes deliver under-voltage or over-voltage power that trips surge protectors and can damage converter boards. Our mobile electricians carry the tools and parts to diagnose and repair the full range of RV electrical issues on-site.

Shore Power, Surge Protection, and Converter Repair

One of the most common calls we receive from Denver campgrounds involves an RV that has power to some circuits but not others after plugging into a 30-amp or 50-amp pedestal. This often indicates a failed converter/charger or a tripped GFCI circuit that isn't obvious from the breaker panel. We carry replacement Magnetek/Parallax, Progressive Dynamics, and WFCO converter modules — the three most common brands in production RVs — and can swap a failed unit in under two hours. We also test Progressive Industries and Surge Guard EMS devices, which frequently need reset or replacement after a campground power surge.

For 50-amp coaches using an adapter at a 30-amp site — a common scenario at Denver-area campgrounds — we check for voltage imbalance between legs A and B that can confuse the converter and cause partial power loss. This is a diagnostic skill that requires a quality multimeter and knowledge of split-phase power, which our technicians carry and apply on every shore power call.

Battery Bank, Inverter, and Solar System Repair

Denver's boondocking culture — with thousands of RV owners camping on BLM land in the mountains along US-285, US-6, and I-70 corridors — means we service a disproportionate number of solar and lithium battery systems. Victron MultiPlus and Quattro inverter/chargers, Renogy and Xantrex inverters, and Battle Born and SOK lithium battery systems all require careful diagnostic approaches when faults occur. We carry a Victron MK3-USB interface to read fault logs directly from Victron systems and can update firmware, adjust charge profiles, and replace failed components on-site.

Cold temperatures dramatically affect battery performance. At Denver's typical January nighttime low of 15°F, a 200Ah AGM bank may deliver only 120–130Ah of usable capacity. Lithium batteries below 32°F require heated battery management systems to charge safely. We help Denver-area RV owners understand why their battery bank isn't performing as expected in winter and can add battery heater pads, upgrade to a temperature-compensating charger, or replace a sulfated AGM bank with a new lithium system.

12V Lighting, Slide Motor, and Wiring Repairs

LED lighting conversion is one of our most popular electrical upgrades for Denver coaches — not only for efficiency, but because Denver's freeze cycles crack the plastic lens housings of older incandescent fixtures, allowing moisture inside. We replace all interior and exterior fixtures with quality LED equivalents from Bezel and RecPro, seal any moisture entry points, and test the full lighting circuit. Slide-out motor and awning motor circuit repairs are also common — the 12V wiring runs to these motors are exposed to road salt from I-25 and I-70 winter travel, corroding connectors and causing intermittent operation. We clean, re-crimp, and if necessary re-route affected wiring runs. If your RV has any electrical mystery — lights that flicker, shore power that won't charge batteries, or an inverter that shuts off without warning — call us and we'll find the cause on-site.
