Common RV problems — symptom-first entry
Start from what you see or hear: warm air, a tripped breaker, a pump that never builds pressure, or ice on the coil. Each link jumps into a full diagnostic article—not a shallow summary.
Symptom hubs exist because RV owners rarely search by component name first. They search “AC not cold,” “breaker keeps tripping,” or “pump runs all night.” This page groups those high-intent patterns and points downward into causes, tests, and repairs.
If you are unsure where to start, open the master troubleshooting guide or the RV parts hub, then return here once you can name the symptom more precisely.
HVAC: cooling, freezing, noise, controls
Roof AC, thermostat, airflow, and electrical interactions.
- AC not cooling Warm air, weak cooling, charge and airflow checks.
- AC freezing up Ice on coil, restricted airflow, or refrigerant issues.
- Low voltage / brownout behavior Compressor stress when pedestal voltage sags.
- AC breaker keeps tripping Separate overload paths from shorted compressor windings.
- Thermostat issues Control signal, display, and comfort logic faults.
- Fan runs, no cold air Divide fan problems from compressor/refrigerant problems.
- AC leaking water inside Drain clogs vs coil icing vs seal issues.
- Furnace not working / not igniting Sail switch, board, and propane sequence.
Electrical: power loss, breakers, charging
Shore cord, panel, converter, and 12V distribution.
- Breaker tripping (whole-coach) Load management vs fault current.
- Battery not charging on shore power Converter output and fuse checks.
- Battery not charging (alias hub) Alternate entry for house battery charge faults.
- Outlets dead on one side GFCI, neutral, and inverter transfer issues.
- GFCI nuisance trips Moisture, loads, and miswired branches.
- Parasitic battery drain Find what stays on when you think everything is off.
Water & plumbing
Pressure, pump, heater, and waste symptoms.
- Water pump troubleshooting Central index for pump-related symptoms.
- Pump runs, no water Dry tank, winterization valves, and suction leaks.
- Low water pressure Regulator, filter, and restriction hunting.
- Water heater keeps shutting off ECO, flame sense, and sediment patterns.
- Toilet will not flush Valve, pedal, and vacuum breaker issues.
- Sink not draining P-trap, vent, and gray line restrictions.
Appliances, slides, inverter
Symptoms that look like one system but tie to another.
