Is Your Camper Heater Not Heating Water?
Your camper heater not heating water depends on multiple factors. Out of which there are two crucial which you need to consider.
Are you getting no water from the faucet when you turn it on, or is there cold water coming out of the faucet when you switch it on?
There can be several reasons for this issue. If there is a water supply in the cold valves, but you are not getting hot water, try hooking the water pump for continuous pressure.
If the water heater tank is full with a pressurized water system and you get cold water in hot valves, check whether the water heater has a water supply.
RV Water Heater Troubleshooting Tips:
When attempting to fix the camper heater, first of all, you need to check what an issue is in the operation of the camper heater. You should first check if the RV hot water heater is not working.
- First of all, check whether the pressurized freshwater is coming inside the water heater inlet or not. You can easily test it by switching on the pressure relief valve, which is present over the top of the water heater.
If you find out that the water is coming out, it is not an issue. Be cautious while opening the valve, as you might suffer from scalding because of the presence of hot water.
- Make sure the propane cylinders are switched on to ensure the appliances are working correctly.
Next, you can light down the water heater and check out the signs and symptoms of any smell of propane leading to the gas valve.
You can also try cracking the gas line where the propane gas line enters your heater’s gas valve.
It is to check the escape of propane by smelling, listening to the sound, or using soapy water that you spread over the fitting.
Secure the heater’s fitting and check for leaks by utilizing soapy water right over the fitting.
- If you have a direct spark ignition water heater in the RV, you need to ensure that it receives 12V DC when switching on the water heater. The wiring schematic is present in the owner’s manual of the water heater.
- RV electric water heater troubleshooting includes the following step. If the RV heater comes with an electric element, make sure when you switch on the electric element, it should present 120 V of electricity, and you can check it safely using an OHM voltmeter.
Check Out The Following Tips For Camper Heater Troubleshooting:
Water Comes With A Foul Odor In The Camper Heater:
The foul odor is present in the water system because of the old water or the presence of stale water within the tanks. However, it might be due to the tanks with water when you go out of town.
It is commonly seen in different parts of the world because of the geological water tables leading to other elements causing the foul water odor.
You can also consider flushing the water system to get rid of the foul odor. Make sure to take professional help for the water system if you’re suffering from foul water by cleaning the water system.
Water Supply Is Not Offering Hot Water:
Is the RV water heater not working? The low pressure can result in several faucets or valves opening simultaneously.
This happens at the time of boondocking or at times when you rely precisely upon the water pumps to supply enough amount of pressure for opening faucets.
Make sure to use one faucet at a time. Still, if the problem persists, you can consider the water pump that offers you more pressure.
Pilot Is Not Lit:
If you’re unable to light the pilot and the camper water heater is not working, you need to do the following. Ensure that the water heater’s thermocouple is alright, centered in flame, and free from any soot or dust.
Plus, it should be screwed tightly with the control valve. Ensure to clean the pilot burner and remove the pilot orifice and the tube. Make sure to clean it properly using compressed air to enhance the opening.
If the problem persists, the control valve is not functioning properly. Make sure to repair it.
Pilot Keeps Opening, But The Burner Won’t Light:
Ensure that your valve is turned on and in position when considering these issues. Check for any obstruction like dust or soot within the orifice, and make sure you clean it.
If the pilot is on, but still there is no gas flow in the valves when you turn it on in an “on position,” you most likely need to replace the valve.
Water Dripping From The Camper Access Panel:
All water heaters and RVs come with a relief valve. As soon as you heat the water, it starts expanding, resulting in steam leading to excess pressure. Stop relief valves help eliminate this pressure automatically as soon as they start working.
And usually, that doesn’t leak. However, if the water is heated to a very high temperature, then the water might start leaking. You can set your camper heater’s temperature settings, which might solve the issue.
If the issue continues, you might need to replace the valves as this can cause camper heater leakage.
Other Common Camper Heater Issues:
It is one of the most occurring problems while using the camper heater. The thermostat of the heater is an essential component that controls the temperature of the water.
The only way to identify the defective thermostat is to replace it by checking the thermostat using a multimeter. If your thermostat is not working, you should replace it.
Before returning it, make sure you turn off the entire power. Next, remove the wire clippings, remove the previous thermostat switch, and replace it using the new one. Lastly, you need to reattach the wire clips and check the power.
Roaring Sound At Times Of Using Hot Water:
Usually, the propane burner makes a roar. This is because they’re burning very lean. There is no perfect balance of the gas by the propane valve to maintain its appropriate balance for working efficiently.
Only professionals can help you adjust the proper airflow within the propane heater. The basic rule of identification is that the flame should appear blue. It indicates the average oxygen level without being too high or low, leading to a yellow or orange tone.
