When I arrive customer told me this job and can be difficult to light the pilot on the furnace it can take up to 2 to 3 hours to do so I began to follow the steps to light the pilot on the furnace pilot will not light but will light on the word set but the flame will go back out again I was unsuccessful of lighting the pilot on the furnace. I gave customer two options of replacing gas valve and igniter and orifice. Customer is going to get a company to fill her propane tanks up to take a look at it if they can’t get a light she’s thinking about getting furnace replace this happens twice a year.
