Furnace Woes

[Joseph Olajos]

Hi All

Problem started last Fall, when our Duo Therm furnace was removed to fix a fan problem;to do the fix, and to get at the fan, the furnace was turned upside-down. Checking the operation of the unit last week, after re-installing it, it was discovered that pilot won't stay lit for more than 20-30 minutes.
Did we disturb some soot or rust particles by turning it over, and if so, what needs to be cleaned out, and using what to do so?
Any help/advice would be appreciated.

Possible thermole coupling problem.

I agree. You do not need to go to an RV store for the thermocouple. Go to your local hardware store and pick one up. You will save a lot of money over the RV store.

Yes possibly but a few months back my thermo coupling on my duo-therm was bad and my pilot would stay on just the burner wouldn't light.
Got new thermo-coupling after blowing out gas lines and everything worked
I think but am not sure that the thermo couplin has nothing to do with the pilot light staying lit.
Make sure your gas lines are free of just air by purging lines and try a few times waiting the recomended time between tries.
Also make sure you hold the button in for at least 1 minute I usually count to 100.
Hope it all works.

Thanx for the replies, suggestions...we'll get back at the unit to see what needs replacing, or just blowing out the lines.

Joe, Remember to disconnect all appliances, fridge. stove top and furnace and water heater if you have one and the regulator too. these gas valves have pressure sensitive parts in them.
I have had a 50% improvemnt. by the flame on the stove top after I blew out my lines.
