What you probably need, you may be able to install yourself and save some$$$. It's call a thermocouple. It's a long thin tube that has a probe bulb at one end and snakes it's way back to the gas regulator.14 years is plenty of service to get from one of these.Don't laugh, but often times you can find a good one on anold gas heater in the metal pile of your local dump. It's worth a peek. If not get one of your heat and cool contractor friends drunk, then ask him to pick one up at the gas company. Town laws vary greatly from town to town. Here in Provincetown we can hardly change a light bulb without a permit...lol. Good luck, I have faith in you. Thanks Dana.
