The pilot generator will not keep the pilot lit. I purchased a new one, checked it with a volt meter and it seems to be working. However, when installed it doesn't work. It is model G01A Any ideas? I'm freezing and there isn't a repair guy in sight.

Re: earth stove gas heater
If this is a newer unit, check for wires at the gas valve that lead up to the to where the heat exchanger is. there is a thermal safety disc up there. Most have a re-set on them. If its an old heater without this safety disc, then if you have checked the pilot generator, and are sure that's not the problem, then it may be the pilot solenoid on the main gas valve.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

bad pressure switch or incorrectly set should have no continuity when off it should when running put on 2000 for ohms should have 500 millivolts when off then turn on and it will start counting down at about 200 should light make sure all connections are good and all safety circuit is good
Check the new thermopile with a millivolt meter and make sure it has the correct output not connected to the gas valve.If it does,then the gas valve is defective.Make sure to test ONLY the thermopile.If it does not generate enough millivolts the gas valve will not open.If the piliot is dirty it will not generate enough heat for the thermopile.Make sure you have a good,strong,blue flame at the pilot.You said the piliot will not stay lit?If not then start by blowing air back through the piliot where the flame comes out with compressed air.hopefully that will clean it well enough.If not you may have to take the pilot tubing loose from the valve and use compressed air to clean it.Make sure when you reconnect the tubing to the valve USE FINGERS ONLY to start tyubing or you may crossthread the tubing....and thats NOT a good thing.Good Luck.
First make sure the flame is at least 1 inch high and hitting the pilot generator (a metal tube about round as a pencil and 3 inches long with 2 wires coming from it to the gas valve). If there is not a good flame, then the burner tray needs to be removed and you need to use a paper clip and clean out the hole on pilot generator. Spiders like to make a nice web in that small hole.Reconnect burner tray and light again. If there is a good flame, the next step will take 2 people and a multi meter. while one person holds down the button on the gas valve to keep the pilot lit, the other person turn the multi meter on and set it to the millivolt setting. Take the 2 leads and touch them to the end of the two wires that come from the pilot generator to the gas valve after holding down the button for one minute with pilot lit, test the millivolts, if the reading is not at least 400 millivolts, then the pilot generator needes to be replaced.
The solenoid inside the gas valve, the part that is supposed to assume the pilot light once the thermocouple is hot, is failing. You need a new gas valve. Your part number is HAXGSV0001 for natural gas or HAXGSVS0003 for propane.
You may need to replace the pilot assembly. Or maybe the gas valve.
Their two stages to the valve and the pilot generates two hundered milivolts (less than a quater of a volt) to open the pilot valve but it takes at least another three hundered or more to open the main half of the valve, You need to have a milivolt meter to check.
The first thing That comes to mind is a bad pilot generator or thermopile. This makes a small half volt charge that energizes the magnets that open the two stages in the gas valve. Next would be a bad gas valve itself. You will need a milivolt meter to check both of these. Lastley is the safty circut. This is the string of switches that can shut the heater down if problems exist. Their are two sets of wires connected to the gas valve. One set goes down to the pilot, this is for the pilot generator. The other set is the safty circut. If you remove these wires and the pilot lightes and stays lit the problem is in the circut. Still no pilot then it is in the pilot or valve. Good luck.
There should be instructions on the inside of the heater access door. Make sure you are comfortable working with gas heaters. Make sure the shutoff valve supplying gas to the heater is on. Turn the gas valve to "pilot", press and hold it while attempting to light the pilot. Once the pilot is lit, continue holding the gas valve knob down for about 30 seconds. The pilot should stay lit once you release the knob. If the pilot stay lit, turn the gas valve to "on". Replace the heater access door and make sure you have proper water flow and attempt to light the heater. If it will not light, or the pilot will not stay on, you will probably have to replace the pilot generator. It provides voltage to run the heater and after time it wears out and produces less and less voltage. A millivolt heater runs on less than one volt so any power loss can be a problem. If you are able, test the pilot generator with a multimeter to see if you are getting at least 500mv when the pilot is on. If not, you should replace the pilot generator or even the entire pilot assembly. Hope this helps...
