RV repairs — procedures and fix-first guides
These pages assume you have isolated a failure mode: they walk replacement, cleaning, reset sequences, and safety boundaries (refrigerant, high voltage, propane).
Repair hubs answer “what do I actually do?” after a symptom page narrows the cause. Prefer measurements first: capacitor microfarads, AC voltage at the unit, water pressure at the hose bib, and 12V at the pump.
When a repair crosses into sealed refrigerant, brazing, or code-sensitive propane work, stop and use Find Local Repair—mobile RV HVAC techs exist for exactly that boundary.
HVAC repairs & deep maintenance
Roof AC: parts replacement, cleaning, and control recovery.
- Replace RV AC run/start capacitor Discharge, match specs, and verify compressor start.
- Replace RV AC thermostat Wiring and compatibility notes for common boards.
- Replace AC fan motor Airflow restoration when bearings seize or windings fail.
- Clean evaporator coils Restore indoor airflow and reduce freeze-ups.
- Reset / recover control board logic When faults latch until power cycle or flow clears.
- Install soft start (compressor inrush) Run AC on smaller generators safely.
- Test AC capacitor with a meter Confirm weak caps before swapping blindly.
- Test thermostat & control path Divide control problems from power problems.
Electrical repairs & verification
Breakers, outlets, converter paths.
Water system repairs & seasonal
Pump, tank, and winterization work.
