If I have a Raywall/TPI furnace that isn't working, is there anything I
can do and or check to get it working again other then call a tech?
The Thermostat seems to work ok. The furnace fan pushes air normally,
but the air ins't getting hot llike it used to. The air out of the vents
is kind of warm but wont get as hot or warm like is used to. It seems
that the furnace just runs and runs and wont shut off without getting
the house warm.
Gas or oil? Can you see or hear a flame? Oil furnaces --- some
have a window iiuc, but others have a round door you can lift to see
the flame, but use a one foot stick, because they get hot. I don't
think a pot holder would be sufficient, and mine would be hard to grip
What part of the country? When was the last time it was serviced?
Remove NOPSAM to email me. Please let
me know if you have posted also.
Electric. It woudl be easier if I had a gas furnace then I could see if
there was flame or not.
All the tags and stickers are upside down including the one inspection
sticker which says Inspected by and 6712011. Other then that I have no
idea of when it was inspected last. I'm in pacific northwest.
That's the factory inspection tag :)
If you don't know how something is supposed to work then you don't know
how to fix it, it's that simple. If it's resistance heat only, then
obviously all of the elements aren't coming in. If OTOH it's a heat
pump, then the possibilities are endless. If you don't know what to
check, then you probably don't know how to check it either, and you
could end up creating bigger problems, you could even get hurt. Worst
case scenario, you burn down your house. Do yourself a favor and have it
checked out out by a professional.
Check the circuit breakers in the main panel. Some electric furnaces
will have more than one breaker feeding it. An electric furnace will
be powered by 240 volts, so it will be fed by 2 pole breakers. Many
electric furnaces have fuses in them. If you can't test the fuses, you
can jusat replace them, but it is best to remove them and test them
with a continuity tester. Turn the power off at the breaker panel
before you remove the fuses. They will be 30 amp and 60 amp cartridge
fuses. This is common in manufactured housing.
Past that will require a service technician. Could be a bad element,
bad heat sequencer, bad wire, bad limit..... You get the idea.
Repolacing these parts is not a DIY job.
If you stare at your furnace really really hard and really really
long.........and click your ruby slippers together 3 times and say,
"There's no place like home".......your furnace should start warming
up. If that doesnt work, replace your thermostat because that's what
everyone always thinks is the problem. If that doesnt work, replace
your furnace because you want one that works
