Suburban Furnace No Heat - Curt Sprenger - 12-02-2009 04:26
Having the no heat issue from the center propane heater, Suburban NT16 SW.
Suburban tells me the NT16 SW was designed for Wanderlodgeââ¬Â¦the W for
Wanderlodge. The NT16 SE looks to be the same unit. Suburban could not
tell me the difference in the two units. Anyone have that knowledge?
Anyone know if the NT16 SE can be used as a direct replacement for the NT16 SW without modifications?

Hi Curt:
Comes to mind that the sw had to do with the center heaters and actually
was for the FC's. The FC's had the ducting under the step in the shower
and that duct had a booster fan that was operated by the thermostat in
the bath. But even if you have to slightly mod for some reason, you
already have the parts from the old unit.
I know of no reason why the SE cannot be used in your Coach, I would put
in a new out side intake/exhaust tube unit with it though and remember
the tubes must slide over the exhaust by 2 1/4 inches. These are easy
to miss and you think it is in place.
Safe travels,

What sort of issue? Do you hear a click click click and no fire? do you
hear one solid click first then click click click? Does the fan run?
Have you removed the front panel, then the cover with the sight glass and
cleaned the probes with a tooth brush? Ran a long cone brush that is used
in the house on the drier lint vent, to clean the top of the beaver
tail?
Is the circuit board getting the signal from the thermostat? Just
some thoughts before replacing, these units are usually pretty bullet
proof but the circuit boards will go out from time to time.

Suburban Furnace No Heat - Chuck Wheeler - 12-02-2009 05:00
When I ordered one for our FC the
difference was the front Cover. The SE plenum vented to the side, the old one
vented to the front. I just used the cover off the old unit. You should check
the current models. Seems like I saw one in a RV store recently and it looked
like they had made some running changes where the old cover might not fit. It
would be trivial for a sheet metal shop to make a correct cover.
BUT, except for the one I replaced because
it had a hole in the firebox, each time I have had a problem with ignition it
has been a problem with dirt around the burner and igniter.

Ralph,
I'm just getting started with this project and building my alternatives sheet.
Usually there is no heat, minimal heat once in a while with t-stat at max. T-stat, fan, click, all seem OK. I can see fire thru the glass when it produces minimal heat
Yesterday I removed the unit. Removed the ignition/sensor unit and cleaned it although is looked fine. The adjustments are correct. Burner looks great. Little dust using compressed air in the fire box.
Need to continue checking...

Suburban Furnace No Heat - Joyce and Richard Hayden - 12-02-2009 05:32

Curt,
I had to get a new NT16 for the FC a few years ago because the heat exchanger was leaking. It had the front cover issue as stated by Chuck and I used the old one. On the PT I have always been able to fix/clean the heater to getthen workingto work. I also remove themto clean and bench test. When I did the units on the PT I don't think they had ever been removed and cleaned. Cleaning works wonders. I did have one, the center one, that had a bad thermostat. Discovered that after I had done all of other things I could think of.

Also need to check the valve on the tree to be sure it is not just
partially turned on for some reason. Have you checked your LP pressure
lately? And are there mud dobber nests in the intake or exhaust ports out
side? These will lower combustion and give you low heat as well.

Suburban Furnace No Heat - freewill2008 - 12-02-2009 05:54
Curt - I just replaced the center furnace in our FC with a NT16SE. This is the
front discharge model. If I had it to do over I would use the ducted model.
(The center FC furnace does not duct under the shower - that is the front
furnace.)
I re-used the original discharge duct that BB had attached to the furnace front
panel. It would have been easier to adapt the duct to the solid front panel of
the ducted model.
Other than the duct and some revisions to the propane inlet the job was easy.
Changing the propane fittings required pulling the new furnace out of its
housing. If you have enough space on the right side of the furnace you can use
the original fittings.
Also, BB cut away part of the furnace housing for clearance on the FC. I had to
duplicate the cut on the new one. This may not be an issue on the PT.
Frankly, if your firebox and flue are in good shape I'd fix the old one. A
dinasaur circuit board and new fan motor is about all it should take. The new
one is cheaply made and considerably noisier.
In fact, until the fan motor packed up, all I had to do to get heat from our old
one was to re-adjust the igniter gap once or twice. Its in the book.

I had a similar problem with the rear
furnace.ÃÂ Even thought I could see flames through the inspection window when I
pulled the burner I found it pretty well clogged.ÃÂ I lightly ran a hacksaw
blade through each slit to open it up and cleaned every thing.ÃÂ It was amazing
how much heat it put out when it was reassembled.
