Frequently Asked Questions​

120V AC system repair involves diagnosing and fixing issues in the RV’s high-voltage electrical system, including outlets, breakers, wiring, transfer switches, and shore power connections.
Common 120V components include wall outlets, air conditioners, microwaves, residential-style refrigerators, water heaters (electric mode), and battery chargers.
Common signs include dead outlets, tripped breakers, appliances not powering on, burning smells, buzzing sounds, or intermittent power loss.
Yes. Damaged shore cords, faulty pedestals, or poor connections can cause voltage drops or complete loss of 120V power inside the RV.
A transfer switch safely switches power between shore power and generator power. Failure can prevent power delivery or cause unsafe conditions.
Yes. Inverter faults can interrupt power to selected outlets or appliances, especially when operating off batteries.
Yes. Low voltage can damage sensitive electronics, motors, and compressors over time, even if power appears to be present.
Yes. Loose connections, overloaded circuits, or damaged wiring can lead to frequent breaker trips or overheating.
Diagnostics include voltage testing, load analysis, breaker inspection, outlet testing, transfer switch evaluation, and wiring checks.
No. Unresolved 120V problems can pose fire risks, damage appliances, and create unsafe operating conditions.
Diagnostics are often completed within a few hours. Repair time depends on wiring access and the nature of the fault.
Inspection is recommended annually, before long trips, after electrical incidents, or whenever power behavior changes.
