I have opened the front of our Lennox G11E gas furnace and the only
operable switch seems to be one that you push or pull for manual or
automatic. There is also an external off-on switch at the top of the
cellar stairs, which does in fact power the furnace off and on. Is
there anything to be tried before I put in a service call?
carefully put the door back on the furnace, and slowly back from it, go
directly to your telephone and call a *competent*, licensed, insured,
professionally trained HVAC technician to come and diagnose the problem(s),
correct them, then pay the man.
Well, if you don't know either, I'm sure glad I also thought of asking
on another group. I can easily pay the man but I can't easily spare
the time for the man to come during business hours.
By the way, you remind me of a church organist we used to have. When
she returned from a vacation in Florida, one church member joked that
they had asked her to leave Florida. I spoke up for her. I responded
that they told her she had to leave because they had enough sunshine
of their own. Understand what I'm getting at?
You are best calling a pro, but does the system try to fire, it could be
simply the thermostat, My new Lux Fan switch didnt operate properly
recently. But it could be alot of things a pro is best to find it
You dont even say if it is getting power or even trying to fire. Is
could be a fuse on the mains mine also has a fuse on the furnace switch
which just came loose once . If its getting power or trying to fire
just call a pro, you probably need a cleaning to.

The heat all rises to the upper floor, leaving the downstairs rather
chilly. But this morning, after I flicked both switches back and
forth last night, the downstairs didn't seem as chilly as before.
Maybe the blower fan got working again? I'll have to see this evening
when the heat kicks in.
I know I cant see it from here and you have a problem..the difference is
that I can fix it.
The other difference is that I wont go poking around with half assed guesses
to try to make it work, and when you pay up, it will work till something
You want to know what to check? OK...ohm you motor, if it is in spec, check
the cap with your tester. If its good, then check the blower door switch,
and if its good,check the limits and if all of them are good, check the
transformer output and if its good.check the control board, and if its good,
do like everyone else does and replace the thermostat and when you cross the
wires up and fry the transformer and control board, and find out that the
local parts house wont sell to an unlicenced person with no clue, call your
local licenced and insured company, and allow them to fix it.
A pro will take about 15 minutes to tell you what is wrong, and another 30
tops to fix it...more than likely...
now...it could be that you have a cracked heat exchanger, or something wrong
with the draft inducer IF you have one...but of course...you want me to open
up my crystal ball and tell you whats wrong with it and I cant even start to
make a diagnosis....
Call someone that can actually SEE whats going on. It might be simple...it
might not be...
You remind me of this Mormon guy we have that hacks in this group....
Understand what I am getting at?
I haven't been getting into the BS here lately but, I have something to
Asking us 'what's wrong with my blower, it won't run?'
Is like us asking you 'my car won't start, can you tell me why?'
Well, you can't tell me anything as to why it won't start, and here is why.
1) You don't know rather I even have the correct key for the car.
2.) You don't know rather the starter is turning the engine over.
3.) Or if the battery has enough power to turn the engine over fast enough
4.) You don't know rather it's getting gas from the tank to the combustion
5.) You don't know rather the coil/coil pack is getting the correct voltage
to produce a 'hot' spark to ignite the fuel mixture.
6.) You don't know rather the plug wires are good going from the coil to the
spark plug, or from the coil to the distributor cap.
7.) Rather there is a burnt wire causing the starter not to engage the
8.) You don't know rather the main battery cables are all corroded and not
supplying enough current to the starter.
9.) Rather the cap and/or the rotor is in satisfactory shape.
10.) Rather the engine has a broken timing belt/chain.
11.) You don't know rather the engine has the correct timing.
12.) You don't know rather this engine has even ran before this post.
This is just a partial list of the unknowns, just like the unknowns that you
have provided for us.
Until you have the knowledge and the tools necessary to test and diagnose
the furnace, nobody here can tell you shit!
Pick up the book or ask a friend how you should call, and get-r-fixed and be
warm, or stay here and be cold.
(take your pick)
BTW, I will not respond to any more of your posts as I don't have the time
to give out free advice to a DIY that could lead to a potentially dangerous
(if you don't under stand this, you need to make another call after you get
an HVAC company scheduled)
