RV Furnace Repair in Dillsburg, PA
No heat, no ignition, or a blower that runs cold.
Mobile service
An RV furnace has a sequence it has to complete: thermostat calls, blower spins up, the sail switch confirms airflow, the board opens the gas valve, the igniter lights it, and the flame sensor proves it. Break any link and the furnace locks out. That is why the most common symptom we see is a blower that runs and runs while the coach stays cold.
Mud daubers in the exhaust tube, a lazy sail switch, a weak blower motor, a dirty flame sensor, and low propane pressure cover most of what we find. Battery voltage matters more than people think — a furnace board that browns out on a tired battery will lock out even with a full tank.
We test through the sequence in order instead of guessing at parts. Most furnace work is done mobile in one visit.
