Michelin RV tire handling problems often stem from incorrect tire pressure, load rating mismatches, or construction differences between tire brands. Most issues can be resolved through proper pressure adjustment, load distribution, or tire replacement with better-suited models.
Furnace that lights for 5-10 seconds then shuts off is classic flame sensor failure. Clean the sensor with steel wool or emery cloth - do not use sandpaper. If cleaning fails, replace the sensor. Located near burner, single wire connection.
Furnace running 10 seconds then stopping is usually sail switch not sensing airflow, dirty flame sensor, or blocked vents. Check blower operation, clean flame sensor, verify air paths clear.
Sailun TerraMax HLT-C tires can work on Class C motorhomes if load ratings match your requirements. Verify your door placard specifications and consider actual corner weights before purchasing.
Furnace running 5-10 minutes then quitting usually indicates overheating from restricted airflow, weak flame, or failing control board. Check combustion air intake, propane pressure, and burner flame quality. Control board becomes suspect if other tests pass.
When your RV propane furnace clicks but won't light, it's usually caused by a dirty or failing igniter, blocked air intake, low propane pressure, or faulty control board. Most issues can be resolved by cleaning the igniter, checking propane supply, and ensuring proper airflow.
Intermittent flame failure varying from seconds to minutes indicates marginal flame sensor signal or airflow issues. Clean flame sensor with steel wool until shiny. Check combustion air intake and exhaust routing. Gas pressure fluctuation also possible.
Furnace blower runs but no ignition usually indicates sail switch, igniter, or gas valve failure. Check sail switch for debris first. Watch for spark at igniter. First run of season may need multiple cycles to purge air.
When your RV furnace clicks but won't ignite, the most common causes are a faulty igniter electrode, blocked burner orifice, or malfunctioning sail switch. Start by checking for proper gas flow and inspecting the igniter for damage or buildup.
When your Airxcel furnace doesn't respond to the thermostat, start by checking the 12V power supply, thermostat wiring connections, and propane supply. Most issues are electrical rather than propane-related.
Suburban SH-42 thermostat circuit is simple - thermostat closes circuit to allow furnace to run. After thermostat replacement, verify both wires are connected tightly at thermostat and furnace. Test by jumping thermostat wires at furnace - if it starts, wiring or thermostat issue.
