Vermont casting rnv40 pilot light works main burner won't light

SOURCE: Pilot lights, main burner will not. Replaced gas valve, no change

I had a problem with the same stove,same model no. etc. Needed new valve. Will replace tomorrow, I will let you know how I make out.

SOURCE: pilot light goes out

The Tstat has a capillary that looks like a thermocouple but it isn't, its a bulb with liquid that expands and contracts based on temperature. A pilot can go out due to a high limit switch being week or getting to hot and that can be shaped like a thermostat capillary or can be simply a disc with a button if even there is a high limit on your stove. There likely isnt. So see the next suggestion.
I suggest lighting the pilot, turning on the main burners while watching the pilot. If the pilot shrinks in size, then check your gas pressures before and after turning it on and seeing if there is a wide variation. I would suggest the pilot is dirty or the pressure regulator is faulty.

Sounds like your regulator could be going out.

The gas may not be reaching the burners. Try match lighting a burner to see if it is. If it isn't do the following.

To solve this problem, first be sure you have adequate gas in the tank. If that checks out OK, do the following:

1. Turn the gas tank valve OFF and disconnect the hose from the tank. If you're using as 1 Lb
Canister tank. Turn the valve off and remove the canister.

2. Wait 5 minutes and reconnect the hose to the tank. Reinsert the canister.

3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

4. Once the tank valve is fully open, light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the same way. Do all the burner flames look correct? If so, you solved
the problem. Remember, to always open the tank valve Very, Very Slowly.

If that didn't solve the problem, you will need to replace the grill's Hose/Regulator Assembly. It runs about $30.00 at any home center or hardware store that sells grills & accessories. Or you will have to replace the Canister Assembly. For that you'll have to go to Tec Grills. If you replace it, turn the tank valve ON Very, Very Slowly.

Hope this helped you.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling.
