RV electrical problems often stem from faulty transfer switches, loose connections, or blown breakers in the main panel. Most 120V shore power issues can be diagnosed by checking the transfer switch operation, main breaker panel, and power distribution connections systematically.
Expert guide to RV 12V DC electrical systems. Covers batteries, wiring, voltage monitoring, and system upgrades.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Keep your RV slide-outs working reliably with this comprehensive maintenance and repair guide.
Depends on dryer voltage. 120V dryers work on 30 amp with load management - turn off AC while drying. 240V dryers require 50 amp service. Check your specific dryer model specifications to confirm voltage requirements.
Most RV heat pumps draw 12-16 amps when running, well within your 30-amp service capacity. However, you'll need to manage other electrical loads to avoid tripping breakers when the heat pump cycles on.
Most RV solar systems range from 200-800 watts using 12V panels wired in parallel with PWM or MPPT controllers. Wire gauge depends on amperage and distance, with 10-12 AWG typical for most installations.
A loud humming noise with a non-starting compressor typically indicates a failed start capacitor, bad compressor, or electrical issue. The start capacitor is the most common culprit and can often be replaced by DIYers with basic electrical skills.
Your Coleman 9420-381 thermostat has failing solid-state switching components causing voltage drop during heating calls. This is a known issue with this model - replace it with a more reliable thermostat or return to a mechanical relay-based unit.
When your RV A/C won't start after a capacitor change, check for blown fuses, thermal switch reset, proper wiring connections, and overheated compressor lockout. The compressor may need time to cool down before restarting.
When RV leveling jacks have no power, check the main disconnect breaker, battery connections, and hidden fuses in the engine bay or basement compartments. Battery polarity issues are rare but can cause system failures.
When a Braun lift stops halfway down and loses power, it's typically caused by a faulty position sensor, loose electrical connections, or hydraulic pressure issues. The fix usually involves checking connections, cleaning sensors, and testing the control module.
Your RV ATS isn't transferring shore power to your AC system due to likely faulty internal contactors or control board issues. This typically requires professional repair as ATS units contain high-voltage components and complex switching mechanisms.
