Furnace blower runs but there is no heat
When the fan runs without ignition, the cause may involve voltage, airflow, a sail switch, limit controls, propane delivery, the igniter, flame sensing or the control board.

Diagnosis before parts
Find the cause, not only the symptom
RV systems often depend on more than one source of power, control or airflow. We inspect the equipment and the supporting RV systems so the repair is based on what is actually failing.
RV furnace will not turn on
A furnace that does nothing may have thermostat, fuse, wiring, battery-voltage, motor or control problems. Diagnosis starts with the power and command path before the heater is disassembled.
Short cycling, weak airflow and unusual noise
Restricted ducts, blocked returns, failing blowers, overheating protection or control faults can cause a furnace to start and stop repeatedly or move too little warm air.
Propane and combustion safety
Propane appliances should not be bypassed or repeatedly forced to ignite. If you smell propane, turn off the supply when it is safe, ventilate the RV, avoid switches or flames and arrange immediate inspection.
Mobile furnace diagnosis
Many furnace complaints can be diagnosed mobile when the RV is safely accessible. Complex equipment removal, duct repair or related water and interior damage may require shop service.

Questions RV owners ask
RV furnace repair: frequently asked questions
Why does my RV furnace fan run without heat?
Low voltage, insufficient airflow, a sail switch, ignition, propane supply, flame sensing or control problems are common possibilities.
Can low battery voltage prevent furnace ignition?
Yes. RV furnaces use 12-volt power for the blower and controls, and low voltage can interrupt the ignition sequence.
Why does my RV furnace keep shutting off?
Restricted airflow, overheating protection, thermostat or control problems can cause short cycling.
What should I do if I smell propane?
Turn off the propane supply if it is safe, ventilate the RV, avoid flames and electrical switches, leave the area and arrange professional inspection.
Do you provide mobile RV furnace repair?
Mobile diagnosis may be available in Orlando, Volusia County and surrounding Central Florida when the location and repair are suitable.
