Identifying AC Unit Problems in RVs
RV AC units can fail for a variety of reasons—some electrical, others mechanical. Knowing what signs to look for can help you determine when it’s time for a professional diagnostic visit.
Complete Loss of Cooling
If the unit powers on but doesn’t blow cold air, or if the fan runs without any temperature drop, the issue could involve refrigerant levels, a bad compressor, or a faulty thermostat.
Short Cycling or Intermittent Cooling
Units that start and stop frequently or cool inconsistently may have a failing capacitor, overheating motor, or improper voltage regulation.
Loud or Unusual Noises
Buzzing, humming, or rattling noises can point to loose components, worn bearings, or obstruction in the fan or blower assembly.
Electrical Issues or Non-Functioning Controls
If the AC system doesn’t turn on at all, or if control panels are unresponsive, problems with the power board, fuses, or relay systems may be present.
Our AC Diagnosis and Repair Process
At Dave's Mobile RV Service and Repair, we provide in-depth on-site diagnostics to identify the exact issue with your RV’s AC unit. Our mobile service unit is equipped to test, repair, or replace most rooftop and interior cooling components during the same visit.
Unit Inspection and Initial Power Testing
We begin by checking the AC unit’s power source, wiring connections, and voltage draw. This step helps rule out fuse or circuit board problems before digging deeper.
Thermostat and Capacitor Checks
Next, we test the thermostat, run capacitor, and start capacitor for accurate response and power delivery. Faulty capacitors are one of the most common reasons RV AC units fail to start or run properly.
Refrigerant System Assessment
While RV rooftop AC units are sealed systems, we inspect for signs of refrigerant loss, compressor failure, or coil freezing that may impact cooling output. If replacement is needed, we advise accordingly.
Fan and Motor Function Tests
We verify fan speeds, motor operation, and airflow output to ensure the unit is functioning at full efficiency. Weak airflow may indicate motor issues, clogged filters, or blocked ducts.

High summer humidity and daytime heat in Dunlap and nearby towns like Pikeville, Whitwell, and Soddy-
Daisy place extra demand on RV cooling systems. We understand these climate conditions and offer real-
world solutions that keep your RV comfortable even during heatwaves.
When to Schedule RV AC Diagnosis & Repair
Ignoring AC problems can lead to further damage, especially with electrical systems that operate under load during peak heat. Addressing early warning signs avoids full system failure or costly replacements.
Frequent Breakers Tripping
If your RV’s breaker or power pedestal keeps shutting off when the AC starts, it’s likely drawing too much power or encountering an internal fault.
Cooling Delay or Noisy Startup
Delays in cold air delivery or unusual noises during startup often suggest failing capacitors or pressure issues in the sealed system.
Unit Runs but Doesn’t Cool Enough
If your AC runs continuously but never seems to reach a comfortable temperature, blocked coils, aging refrigerant components, or failed sensors could be to blame.
Post-Storage System Check
After winter storage or long periods without use, testing the AC system before your first trip helps ensure it works when you need it most.
