When an RV water heater pilot light won't stay lit after releasing the button, it's usually caused by a faulty thermocouple that needs cleaning or replacement. The thermocouple is a safety device that detects the pilot flame and allows gas to flow.
Propane regulator freezing is normal in cold weather due to rapid gas expansion cooling the regulator. Installing a regulator cover and using slow gas flow can prevent freezing issues.

Onan code 36 indicates a low fuel pressure issue in LP generators. This typically means a problem with the LP regulator, fuel solenoid, or gas line obstruction preventing proper fuel flow to the generator.
While there's no direct plug-and-play replacement for the Atwood GC10A-4E with a gas-only tankless unit, you can upgrade to dual-fuel tankless heaters like the Girard GSWH-2 or Truma AquaGo. These maintain electric capability while providing instant hot water and better efficiency.
When your RV furnace blows cold air but won't ignite, the problem is usually a dirty flame sensor, blocked air intake, faulty ignition board, or gas supply issue. Most ignition problems can be diagnosed and fixed with basic cleaning and component checks.
You can replace your Atwood 10-gallon water heater with a Furrion tankless model, but it requires significant plumbing and electrical modifications. The Furrion Tankless Water Heater (FTH-1215) is the most compatible option, typically costing $800-1200 plus $500-1000 for professional installation.
Chassis battery drain is typically caused by parasitic draws from electronics, clock radios, or converter issues. Dead outlets near dinette/kitchen suggest a tripped GFCI or loose connection in that circuit.
For F53 chassis wheel bearing service, contact Ford dealerships or heavy-duty truck shops since Camping World doesn't service motorhome chassis. Your beeping propane detector likely needs replacement, and the slides are interlocked with the LP detector for safety.
Most RV heat pumps draw 12-16 amps when running, well within your 30-amp service capacity. However, you'll need to manage other electrical loads to avoid tripping breakers when the heat pump cycles on.
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.
To add electric heat while keeping the anode rod, look for kits that install in the drain port or use a combo anode/element. Avoid kits that replace the anode port entirely on cast iron tanks. The anode is critical for tank longevity.
Furnace rumble and backfire indicates air-fuel mixture problems. Check gas pressure at manifold, deep clean burner by soaking, and inspect heat exchanger. Delayed ignition from weak spark or dirty igniter also causes this. May need replacement on 20+ year unit.
Girard II tankless requires different wiring than DSI tank heater. Run new 10 gauge 12V power with 30A fuse. Do not reuse old DSI harness. Follow Girard diagram exactly for proper operation.
