Frequently Asked Questions
What does a sail switch do in an RV furnace?
The sail switch is a safety device that physically moves when air flows through the furnace. This movement closes an electrical contact that signals the control board that proper airflow exists. Without this signal, the furnace won't attempt ignition, preventing dangerous conditions like incomplete combustion or carbon monoxide buildup.
How do I know if my sail switch is bad?
Common symptoms include: furnace blower runs but won't ignite, furnace attempts ignition then shuts down immediately, error codes related to airflow or limit switches, or furnace works intermittently. The sail switch can fail due to dust buildup preventing movement, broken sail blade, or worn electrical contacts.
Can I test my sail switch before replacing it?
Yes. With power off, you can manually move the sail blade and use a multimeter to check for continuity when the switch is activated. However, even if it tests good electrically, a sticky or sluggish sail blade that doesn't move freely with airflow will still cause furnace problems and should be replaced.
Is this difficult to replace?
Most RV owners with basic tools can replace a sail switch. It typically involves removing the furnace cover, disconnecting two wires, removing mounting screws, and reversing the process with the new switch. Always turn off power at the breaker and allow the furnace to cool completely before working on it.
