Your Onan 5500 generator's fuel pump chatter and dual light illumination indicates a control board communication error triggered by the remote harness connection. This comprehensive guide covers diagnosis, repair steps, and prevention strategies for all common Onan 5500 issues.
The RC7-GS inverter charger can properly charge 105Ah AGM batteries using the 125Ah setting, as AGM charging is voltage-based, not capacity-dependent. Generator start issues typically stem from wiring problems or incorrect DIP switch configurations.
Your Coleman Mach AC unit on the 2019 Rockwood Minilite 2509s has developed a short circuit that's drawing power even when the AC is off. The fact that the fuse blows before it's even fully seated indicates a direct short to ground in the AC circuit.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
When your Norcold 1210 isn't cooling despite showing no error codes, the most common causes are cooling unit failure, poor ventilation, or low DC voltage. Check airflow, clean coils, and test voltage before considering cooling unit replacement.
Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
When your Dometic RV air conditioner runs but doesn't blow cold air, the most common causes are dirty air filters, blocked condenser coils, low refrigerant, or faulty capacitors. Start with cleaning filters and coils before checking electrical components.
Fix your RV refrigerator with this guide covering Dometic, Norcold, and residential fridge issues.
You can replace a failed Atwood Levelegs control system with a GAMA Electronics RF340-4PR-ASL controller for around $235, which is much cheaper than OEM replacement or repair. This aftermarket solution provides better reliability and easier troubleshooting than the original Atwood system.
While Splendide drum bearings are sealed units requiring drum disassembly for replacement, you can extend their life with proper maintenance. A failing bearing can continue operating for months but will eventually seize, requiring professional repair or unit replacement.
When a Norcold refrigerator starts on propane but shuts off after 1-2 hours, it's typically due to a failing thermocouple, dirty burner, or control board issue. Most problems can be diagnosed by checking the flame appearance and thermocouple connection.
Your MaxxAir/Fantastic fan is likely experiencing a moisture sensor malfunction or rain sensor false trigger. The fix typically involves checking sensor connections, cleaning contacts, or adjusting sensitivity settings.
When your RV furnace blows cold air but won't ignite, the problem is usually a dirty flame sensor, blocked air intake, faulty ignition board, or gas supply issue. Most ignition problems can be diagnosed and fixed with basic cleaning and component checks.
Furnace that lights for 5-10 seconds then shuts off is classic flame sensor failure. Clean the sensor with steel wool or emery cloth - do not use sandpaper. If cleaning fails, replace the sensor. Located near burner, single wire connection.
When your HWH 625S slide solenoids work manually but not from the switch, the issue is likely in the control box wiring or internal components. You can bypass the control box by connecting switch wires directly to solenoid wires, but proper diagnosis should be done first.
