A cold night in an RV with a heater that will not light points at the gas path, the spark or the burner, and rv propane heater repair starts by sorting the gas path, the spark and the burner. The fix is often a hose, an igniter electrode, a burner tube or a control part, .

The quick answer
Most RV propane heater faults come down to gas supply, spark or burner parts. Start with the hose and regulator: the NQN listing states that only one regulator may sit between the RV propane source and the appliance, so an extra regulator can starve the burner. Next, check the spark: the 93868 igniter electrode and the 91365 ignition circuit board in the Lrichy kit (on Amazon) cover ignition failure, while the 91447 thermal cutoff and the 93866 thermostat kit cover a heater that lights and then quits. For a weak flame, the 93844 gas valve and the 91638 burner tube in the AutoAlly kit (on Amazon) cover leaks, intermittent lighting and poor combustion.
Step 1: Check the gas supply and hose
A heater that will not light at all may have no gas at the burner. The NQN 12 ft hose uses a 1/4 in quick disconnect with a safety shutoff valve and a 3/8 in female flare fitting, and the PalpitateC 12 ft hose uses a POL tank connection with a two-stage control valve for 20-100 lb gas tanks. Both state a gas-tight connection, and the PalpitateC hose (on Amazon) connects to the tank without tools. Keep the tank at a distance, and remember that only one regulator belongs between the source and the appliance. A propane leak detector for RV use can confirm a fitting is sound; see the best battery-operated propane leak detectors.
Step 2: Check the spark and ignition parts
If gas reaches the burner but nothing lights, the spark path is suspect. The Lrichy kit pairs the 91365 ignition circuit board with the 93868 spark probe igniter electrode, the 91447 thermal cutoff and the 93866 thermostat kit, and it includes an installation guide manual. In the AutoAlly kit, the 93868 igniter comes pre-set to a 1/8 in gap, so no adjustment is needed at install. A heater that lights and then dies may have a failed thermal cutoff or thermostat, so match the symptom to the part. See the RV hot water heater parts guide.
Step 3: Check the burner tube and gas valve
A weak flame points at the burner and the valve. The AutoAlly kit states that the 93844 solenoid valve stops gas leaks and intermittent lighting, and that the 91638 burner tube boosts combustion with an adjustable air shutter and a flame deflector. The kit fits Atwood 6-10 gallon models and the EXT series, while Dometic fit covers the 91638 burner tube only. If the flame stays weak, look back at the hose and regulator from Step 1.

NQN 12 Ft RV Propane Hose
A 12 ft stainless steel braided hose with a quick disconnect, a shutoff valve and a 1 lb adapter for RV grills and heaters.
Pros
- CSA Certified braided hose with solid brass fittings
- Safety shutoff valve built into the quick disconnect
- Working temperature of -22°F to 122°F stated
- 1 lb adapter included for grills and appliances
Cons
- Only one regulator belongs between source and appliance, so the RV regulator may need removal
- The listing mixes low voltage and low-pressure wording for the RV connection
- Made for a low-pressure propane system only
- No model list is given, so fit depends on the 1/4 in and 3/8 in fittings
Detailed Review
The listing states a 12 ft stainless steel braided hose with a 1/4 in quick disconnect, a safety shutoff valve, a 3/8 in female flare fitting and a 1 lb propane regulator adapter, with solid brass fittings and CSA certification, and a working temperature of -22°F to 122°F. It says the hose suits Weber Q series and Coleman portable grills, a propane heater and most RV appliances on a low-pressure propane system, with only one regulator between the RV propane source and the appliance. One bullet calls the RV connection a low voltage line, while the application note says low-pressure propane, so trust the low-pressure wording. The kit also includes 2 Velcro stickers and sealing tape.
Who it's for: RV owners who want to run a grill or portable propane heater from the RV quick connect without a separate tank. Who should skip it: owners on a high-pressure line, or anyone whose setup needs a regulator at the appliance too.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. Safety here means a gas-tight connection, a shutoff valve, a thermal cutoff or a stated certification, and the NQN hose (on Amazon) earns the strongest safety mark for its CSA certification and shutoff valve. 1 of the 4 listings states a warranty term: the Lrichy kit at 18 months. The other 3 state no term. How we pick explains the weights.
FAQ: power away from the grid
Why does my RV propane heater fail to light?
A heater that will not light usually lacks gas, spark or both. Check the hose and regulator, then the 93868 igniter electrode and the 91365 ignition circuit board.
What parts fix an RV water heater that lights and then quits?
A heater that lights and then quits often points at the thermal cutoff or the thermostat. The Lrichy kit includes the 91447 thermal cutoff and the 93866 thermostat kit with the 91365 board and the 93868 igniter.
Can I run a portable propane heater from the RV quick connect?
Yes, if the heater suits a low-pressure propane system. The NQN 12 ft hose connects a 1/4 in quick disconnect to a 1 lb adapter, with only one regulator between the source and the appliance.
Do I need a regulator on both the hose and the appliance?
No. The NQN listing states that the gas connection accepts only one regulator, so remove the regulator on the RV or trailer if the appliance already has one, or gas flow will drop.
