When your RV dash A/C blower motor stops working, check for hidden inline fuses installed by the RV manufacturer before looking at complex electrical issues. These aftermarket fuses are often tucked under the dash and not shown in Ford chassis diagrams.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
When your Dometic RV air conditioner runs but doesn't blow cold air, the most common causes are dirty air filters, blocked condenser coils, low refrigerant, or faulty capacitors. Start with cleaning filters and coils before checking electrical components.
For Ford F53 chassis, look for existing rubber grommets near the brake pedal assembly or steering column area. You can also use the main harness grommet where factory wiring passes through the firewall.
F53 460 timing marks on harmonic balancer viewed through timing pointer. Clean and mark with white paint for visibility. Use timing light at idle.
Yes, restricting airflow too much can damage your Advent A/C by causing coil freeze-up or compressor strain. The dividing wall is removed to eliminate air turbulence and improve ducted airflow distribution.
Yes, you can safely add a manual ball valve to your '08 Fleetwood Terra's heater line before the electric valve. This will function identically to the electric valve and won't cause flow issues since the system is designed to handle closed valve conditions.
Your Coleman 9420-381 thermostat has failing solid-state switching components causing voltage drop during heating calls. This is a known issue with this model - replace it with a more reliable thermostat or return to a mechanical relay-based unit.
When your RV A/C won't start after a capacitor change, check for blown fuses, thermal switch reset, proper wiring connections, and overheated compressor lockout. The compressor may need time to cool down before restarting.
Coleman Mach heat strips can be added using the Heat-Ready Control Box. This adds electric heat through your AC while keeping furnace independent. Verify AC model compatibility and check electrical capacity - heat strips draw significant amps.
Heat pump running one second then stopping usually means bad capacitor, low refrigerant, or thermal overload. Check capacitor first - its the most common cause and cheapest fix.
Shutting down under load after rebuild suggests carburetor still not delivering enough fuel or governor sticking. Watch governor arm movement during load test. Try gradual load increase to find threshold. Check fuel pump output if equipped.
Heater core supply typically from intake manifold or head. Trace hoses from firewall. Supply comes from upper engine, return goes to water pump area.
Reduce RV noise with sound deadening on doghouse, mass loaded vinyl, and weatherstripping. Address rattles with felt pads. Expect improvement not perfection.
In the Bay Star 3826, the half bath black tank vent typically runs through or near the electrical cabinet, while the rear bath vent usually routes through the bedroom wall cavity or bathroom wall up to the roof. Both vents terminate at roof-mounted vent caps.
