RVTI Practical Exam 2026/2027 | 250+ Practice Questions, Correct
Answers & Detailed Explanations
SECTION 1 — PROPANE SYSTEMS
1. During an RV inspection, a propane appliance does not operate.
The technician has already confirmed adequate electrical power.
What should be checked next?
A. Replace the control board
B. Check propane supply and the appliance shutoff arrangement
C. Replace the thermostat
D. Replace the battery
Correct Answer: B
Rationale: Propane availability and the appliance's shutoff
arrangement must be verified before replacing electrical
components. A technician should diagnose the supply path
systematically.
2. A technician notices a strong propane odor inside an RV during a
pre-delivery inspection. What is the most appropriate first
response?
A. Turn on all appliances to locate the leak
B. Ignore the odor if the appliances operate
C. Stop the inspection and follow the applicable propane safety
procedure
D. Increase the propane regulator pressure
Correct Answer: C
Rationale: A suspected propane leak is a safety issue. The technician
should stop normal operation and follow the manufacturer's and
applicable safety procedures before continuing diagnosis.
3. During a propane-system inspection, the technician finds a
damaged flexible propane line. What should be done?
A. Wrap it with electrical tape
B. Continue the inspection
,C. Repair or replace it according to the approved procedure
D. Increase regulator pressure
Correct Answer: C
Rationale: Damaged propane components should not be improvised
or bypassed. The component must be repaired or replaced using an
approved method.
4. An RV furnace repeatedly fails to ignite. Which item should be
verified before replacing the furnace control board?
A. Exterior graphics
B. Propane supply and required electrical inputs
C. Cabinet finish
D. Window screens
Correct Answer: B
Rationale: A technician should verify the basic inputs required for
operation before condemning a control board. This prevents
unnecessary parts replacement.
5. A propane appliance operates normally on one burner but
another appliance fails. What is a useful diagnostic approach?
A. Replace both appliances
B. Verify whether propane is reaching the affected appliance
C. Replace the RV battery
D. Remove the regulator
Correct Answer: B
Rationale: Comparing operating and non-operating appliances can
help isolate whether the problem is localized to the appliance or its
supply path.
6. During inspection, the propane regulator appears physically
damaged. What is the best action?
A. Adjust it immediately without testing
B. Ignore the damage
C. Follow the approved inspection and replacement procedure
D. Paint over the damage
,Correct Answer: C
Rationale: Regulators are safety-critical components. Physical
damage requires evaluation according to approved procedures
rather than an improvised adjustment.
7. A technician is checking propane appliance operation. Why is
ventilation important?
A. It increases battery capacity
B. It helps provide appropriate combustion air and prevents unsafe
accumulation of combustion products
C. It reduces tire pressure
D. It charges the converter
Correct Answer: B
Rationale: Proper combustion requires appropriate air supply, while
appliance exhaust must be safely discharged. Ventilation problems
can create serious safety hazards.
8. A furnace starts but shuts down shortly afterward. What should
the technician do first?
A. Replace the furnace
B. Determine where the normal operating sequence stops
C. Remove the thermostat
D. Disconnect the propane regulator
Correct Answer: B
Rationale: Understanding the sequence of operation allows the
technician to identify the failed stage instead of replacing
components unnecessarily.
9. An RV water heater has propane available but does not ignite.
Which diagnostic step is appropriate?
A. Verify the ignition-related inputs and operating sequence
B. Replace the RV tires
C. Disconnect the battery permanently
D. Remove the water heater
Correct Answer: A
, Rationale: The technician should determine whether the appliance
receives the required electrical and propane inputs and where the
ignition sequence fails.
10. A technician smells propane near an appliance connection. What
should not be done?
A. Follow safety procedures
B. Isolate the affected system as required
C. Use an open flame to locate the leak
D. Ventilate as appropriate
Correct Answer: C
Rationale: An open flame must never be used to locate a propane
leak. Approved leak-detection methods and safety procedures must
be used.
11. During an inspection, a propane appliance has a damaged vent
termination. What is the appropriate response?
A. Ignore it because the appliance still operates
B. Repair it according to manufacturer requirements
C. Cover it with tape
D. Remove the vent
Correct Answer: B
Rationale: Appliance venting is part of safe operation. A damaged
termination must be corrected according to the manufacturer's
requirements.
12. A technician observes soot around a propane appliance exhaust
area. What does this indicate?
A. The appliance is always operating correctly
B. The combustion system requires investigation
C. The battery is fully charged
D. The refrigerator is level
Correct Answer: B
