COLEMAN Series COAT - COAS Oil Gun Furnace
Posted: Wed Dec 24, 2008 12:22 pm
I’m fairly technically inclined, I have worked on gas furnaces, but never on oil furnace. I thought that perhaps at least the first time I should have a professional do a tuneup and that I could watch and learn. My furnace works but occasionally doesn’t light. I replaced the fuel filter, and figure it probably needs a clean nozzle and to have the electrodes cleaned. It seems to have more difficulty lighting when it’s cold ( that figures). I thought perhaps it might be water or related gelling restriction so I replaced the filter and bled out the line, added a watered dispersant and had the tank topped off. It really didn’t seem to help that much, it perhaps works a little better if any. I’ve already purchased and have in my possession a couple of spare nozzles that meets the manufacturer’s specifications.
I’ve been trying to find a professional furnace service company to tune up my furnace (Hopefully local with reasonable rates). So far I haven’t had any luck; I’ve called several companies and so far they’ve all told me they don’t work on motor homes/trailers/trailer parks.
I was hoping for two things.
1) Hopefully someone can tell me of a service company in (Northern) Cincinnati, Ohio that would service my furnace at reasonable rates.
2) Any advice on nozzle replacement if I can’t find someone in my area to reasonably service my oil furnace or if I choose to do it in the future.
Another reason I’m reluctant to do it myself is that I have a bad back. A hour or so worth of work is liable to take me several days and liable to put me in severe pain for many days. It might require strength and contortions that I’m not sure I can do. It looks like the pump, motor and burner comes out as an assembly; I suspect it’s about 40 pounds. I’m not sure I can handle it. It looks like there’s three or four main bolts holding the assembly in. If there is a fourth I’m not sure I can get to it.
I tried the service Company but they told me they didn’t work on mobile homes.
