My vanguard heater model gvr50bp lights up and

Make sure all the wire connections are good and tight. Next lift off the cover and look for a little thermal disc mounted up by top of the heat exchanger. Most have a re-set button but not all. If you have this ,by-pass it ,see if that solves the problem, if so it may be defective, or doing its job and you have a venting problem. If you don't have this and have changed the thermocouple (was it a copper tube with a fitting that screwed into the gas valve, or did it have 2 wires, that is a pilot generator, kind of same thing) make sure the probe is set correct, with the pilot flame heating the top 1/3rd of the probe. The only thing left is the gas valve.

Hi slowjam I am assuming it is a Natural Gas Heater. All it needs is a good blow out with compressed air. They tend to carbon up in the pilot light area. You will probably also find it is very dusty inside. Easiest way to clean the carbon out is to remove the hose at the heater and with compressed air blow through the fitting where you have removed the hose. Make sure you hold down the start button so the air can get through to the pilot light and jets. Don't connect the electricity for the fan when you do this. If you can get to the pilot light may pay you to hit it with some compressed air as well. Hope this helps. Regards Bryan

hi there
OK i read your report. did you try to blow bottom and around pilot real good with a can air. If not try that because even thou might not seems like its need cleaning but it dose. during the summer when it's not in use it will collect dust and bugs and it will seems like something is wrong but it's not just need to be clean real good. and another thing get a paper clip and clean the inside out make sure its clean. i know when you light it on but it stay on for a little bit. do those things and let me know how it went.thank you for writing to fix ya.

Best Regards richards

You got to heat the thermocouple to get the gas valve to open ... I guess you know that ... You checked for spider web???

Hi the thermocouple is a long copper wire that goes back to the gas valve from the pilot .

i would clean the flame senser first , then check the pressure switch jump this out , then check the fan control or snap disc jump this out see if it runs if you need A THERMOCOUPLE then honeywell universal will do
