I have a trailer house furnace and the thermocouple apparently is going bad because the pilot goes out once every week or two. It just started doing that this fall, after the pilot was off all summer. I was at a local building supply and saw they sell a packaged thermocouple, but it does not specify what its for. Are all thermocouples created equal? I mean, can they be used for ANY furnace, or water heater, or any gas appliance? I am hoping so, because I dont know where I'd get one specific to this older Miller (mobile home) furnace.
PS. If I could figure out how, I'd convert it to electronic ignition, but that seems like a big job.
Thanks
