If rooftop line voltage or start parts are outside your comfort zone, stop and use the button below.
In Orlando, frequent breaker trips can indicate serious issues with your RV AC system. This page helps you diagnose the problem and understand the likely causes.
Fast read: Overloaded circuit or faulty compressor (high). In Orlando, the combination of high heat and frequent voltage drops often leads to increased current draw, causing breakers to trip.
In Orlando's high humidity, airflow restriction and coil freezing are more common causes than refrigerant issues.
Answer each question in order—your path should match the branch chart when it is visible.
In high heat and humidity, RV AC units work harder, leading to increased electrical demand. This can cause breakers to trip if the system is overloaded or if there are faults in the components.
Frequent voltage drops in high-occupancy parks can exacerbate these issues, causing the AC unit to draw more current than normal, which may lead to breaker trips.
Long AC cycles during peak tourist seasons can also stress the system, making it more susceptible to electrical failures and overheating.
The branch chart is not shown on this view so you can rely on the written steps without layout issues. Use the numbered list in Follow this sequence above—the same checks in order. You can print this page or take it to the roof on a phone or tablet.
Work in this order: thermostat and mode, then return airflow and filter, then rooftop power under load, then start parts such as capacitor and contactor, then sealed refrigerant only with a licensed tech.
| Fix path | What you do | Cost band |
|---|---|---|
| Replace breaker |
| low |
| Inspect compressor |
| medium |
| Check wiring |
| high |
Repair when one serviceable fault matches your checks and the part can be fixed without breaking refrigerant integrity. Replace when failures repeat after a good repair, the sealed system is compromised, or economics favor a new unit.
Bench procedure: Run one path at a time, re-test, then move on only if the symptom changed.
| Fix path | What to do | Goal |
|---|---|---|
| Replace breaker |
| Ensure the breaker is rated for the AC unit's load to prevent trips. |
| Inspect compressor |
| Check the compressor for signs of failure or overheating. |
| Check wiring |
| Inspect wiring for damage or corrosion that could cause resistance. |
| Tool | Purpose | Difficulty |
|---|---|---|
| Multimeter | AC volts at pedestal and rooftop under load, plus continuity checks where applicable. | Easy–medium |
| Insulated screwdriver set | Access shroud, control box, return path, and electrical terminations with the correct bit sizes. | Easy |
| Clamp meter | Clamp AC amps on the load side of the contactor to verify each motor branch is actually drawing under command. | Medium |
Tools are for measured checks only. Live AC and charged capacitors can shock or start a fire. If a step is outside your training, stop forcing progress and continue in When to stop DIY below.
If your AC is still tripping the breaker after these checks, most RV owners in Orlando stop DIY here. A technician can quickly confirm the issue.
Check your power connections and ensure your pedestal is functioning properly.
Repeated breaker trips in this climate deserve a hands-on electrical check before further damage occurs.
Overloaded circuit or faulty compressor (high confidence). In Orlando, the combination of high heat and frequent voltage drops often leads to increased current draw, causing breakers to trip.
Regularly inspect and clean the AC unit to prevent overheating.
Ensure the electrical system is properly rated for the AC load.
