My pilot light will not stay lit. Somebody told me to change the thermocouple. I need to know how to get the old one out.

Thanks

Is this a mobile home? If it is you have to pull the entire burner out, change the thermocouple and purge the system upon re-assembly to get the gas to the pilot to lite.

If you are not mechanically inclined or do not know what you are doing I suggest you call a professional. Gas especially propane gas can be dangerous to work on.

Now if it is not a mobile home then the thermocouple will be right in front of the furnace mounted to the burner area along with the pilot just remove and replace.

On mobiles you usually have to unbolt the entire burner assembly plate from the furnace.This is after you disconnect the electric and gas line.
