Question about GE Heating & Cooling
If your furnace is older than 1978 it has a standing pilot, which means it exists full time and is not intermittent in operation requiring a spark or hot surface ignition to ignite the pilot or pilot rail leading to the main burners.
If you depress the pilot valve button and light the pilot and hold it in for a minute maybe 2 and it drops out, the thermocouple is usually why. The thermocouple creates 30 millivolts of electricity, this is not very much power a millivolt is 1/1000th of one volt.
The 30 mv power is enough to hold the pilot valve open after you release the button after lighting the pilot, the replacement of the thermocouple is easy and they are available at any hardware store, they come in varying lengths, it is better to get one a bit longer than not long enough, you can loop the remainder.

SOURCE: wont stay lit
go to this site www dot desatech dot com. Here you'll find parts to repair your heater. a propane heater uses a millivolt generator to sense the flame. along it's cappilary are two push on spde connectors. these connect to the high limit temperature sensor which is mounted on the flame backplate of your heater. to see if it is the high limit shutting down your heater, jumper across the two spade connectors. if the heater stays on, this is your problem. if the flame still goes out, then the millivolt generator is shot.

The oven pilot is accessible through the broiler door, (you're pretty much laying on the floor to light it) or through the oven bu removing the oven bottom panel. To remove the oven bottom, place fingers in holes near the door, and apply pressure to slide the bottom toward the rear, and lift when the front (by your fingers) comes free. Remove completely and set aside. You should now see a flame spreader (V-shaped metal pan) retained by one or two winged screws. Removing the screws allows removal of the spreader. This exposes the burner, complete with pilot. There is two tubing lines to the pilot assembly, one about 1/4 inch dia. and one much smaller. the one at the end of the 1/4 inch tube is the pilot. The piece at the end of the really thin tube is the thermocouple. You have to heat the thermocouple to get the gas to come on to the pilot. A match just won't do it as you need to apply a flame to the thermocouple for about 30 seconds or so. Heat the thermocouple until the pilot will self-sustain. When the pilot stays on on it's own, put it all back together. If you elect to just go through the broiler, again heat the thermocouple until the pilot will self-sustian.

You may need to replace the Thermocoupler. It screws into the gas regulator and the sensor end is set in the flame of the pilot light. You can get one at any appliance parts store. The Thermocoupler simply feels the heat of the pilot light and sends a very small amount of voltage to the gas switch that opens when your thermostat calls for heat. If the pilot light isnt lit, no voltage from the sensor and no gas can be released by the regulator.
Anyone can replace one. Just find the tip that sits in the the pilot flame when you try to ignite the pilot light. Follow it down to the regulator and unscrew it. There is no gas involved. It is Ultra Low Voltage. No danger.
Be sure to turn off the power to the unit before you begin removal. Take it to the parts store along with your furnace brand and model number. If you see any identifiers on the regulator, note them and take them with. When you replace it be sure to have the sensor end up in the flame of the pilot.

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.
