Atwood White Rodgers pilot lights, but main burner doesn't come on. Thermocouple line is kinked, but it appears to be working since the pilot stays on. How do I know if the valve needs to be replaced?

SOURCE: burner lites but goes out after 2 or 3 min.

the white rodgers gas control needs to be replaced;
the way it works is: the thermocouple opens the pilot gas circuit and, holds it open
when it heats up by creating a magnetic field in the gas control then: when you turn
the knob on the gas control to "on" a valve inside the gas valve opens the main gas circuit and, electricity supplied by your RV keeps it open.
the main gas coil inside the gas valve is defective and, can not hold the main gas circuit to the burner open anymore.

I think you need to reposition the thermocouple, or adjust the pilot gas pressure by adjusting the pilot screw make sure it is still the recommended gas pressure of the system... please contact a HVAC tech if this things did not work.

U can light the pilot lite,turn 2 ON it will stay lit 4 a couple of minutes then go out? If u turn the knob 2 low,med. It goes out pretty much immediately?I changed the thermocouple,blew the lines ou


Is the thermocouple secure, routed properly, no kinks, no sharp bends? Is the end of the unit properly aligned so the hottest part of the pilot flame is hitting the unit. Did you hold pilot switch in the light position for at least 30 seconds, before you set the gas valve to on? If all above OK, try this. Light the pilot using barbeque lighter once it lights keep the lighter on the t-couple for 30 seconds, then set the valve to ON and keep the lighter where it is. Once the main burner lights, remove the lighter. If the burner and pilot go off, your gas valve is bad.

We have an atwood lp gas water heater 6 gallon g6a7 white rogers control. The pilot lights but when we turn it to on it goes out, even after holding it up to a minute. It was running fine, we thought we...


If pilot stay lit, then thermocouple is working.
If pilot will light, then you have gas. If pilot goes out when pilot button is released, then thermocouple is next suspect.

Thermocouple tip must sit in pilot flame.
The pilot light heat applied to two different metals inside thermocouple causes small current.
The current travels back to gas control valve through copper line.
If the gas valve receive this current, then a magnetic switch stays open and allows gas into the gas control valve.
The magnetic switch is on the end of the red button you push down when lighting pilot. Essentially the red button is an override to the magnetic switch.
If the gas control valve does not receive the current, then the magnetic switch does not stay open when you release the red button.
When replacing thermocouple, note that it is not screwed very tight into the gas control valve. Finger tight + 1/4 turn. If it is overtightened, then the small thermocouple current shorts out against the gas control body.

I have a Jayco pop up with an Atwood water heater, serial # 37C14U-5. My problem is two-fold. The water heater pilot doesn't stay lit after initial run, and propane is leaking out of the vent on the...


Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

Pilot will light after 30 seconds when you try to move knob to on position the pilot goes out and heater won't ignite.


You need to replace the thermocouple.
When you light the pilot it is supose to heat the thermocouple.
the thermocouple produces a small electric current which allows the gas valve to open and keep the pilot going. and allowing the main burner to come on.

MAIN BURNER WILL NOT IGNITE


Any RV sales and service dealer can get parts for you, if they don't already have them in stock. Is the pilot staying on at all? If yes, what happens when you turn from pilot, to On? One easy thing to try is undo thermocouple (probe that sits above pilot flame) from gas valve (3/8" wrench) and clean the end of the thermocouple with fine steel wool, as well as spray some WD-40 into the hole it came out of, and give it a blast of compressed air after to clean it out as well. (protect your eyes) Then re-install the fitting and snug it up good, and try lighting again. You may get lucky that it's just corroded or dirty, and this may cure that.

After a few minutes of burner heating the water, gas shuts off.


A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.
