I have a Coleman mobile home furnace and my pilot light keeps going out. I have replaced the thermocouple twice, cleaned the orfice, replace the gas regulator with a brand new one, and even crawled up on my roof and checked my Flue, my propane tank is fuel so i know its got propane going into it. This is what keeps happening. I get the pilot light lit and it will run and warm the mobile home up and then when it shuts down/cools it may kick back on a couple times but then sometime later the pilot goes back out and i cant figure out why and what is going on. Can you help me give me any ideas on why it keeps doing this?
