My 1989 Paragon Tnf-82-3 decided to take a vacation leaving the following
blinking messages, O P E N F A I L, O P E N F A I L. I lost the
instruction manual several years ago. Does anyone out their know what part
of this kiln actually failed?
TIA, Fran

I would guess that you "broke" an element leaving an "open" circuit.

Your thermocouple is either faulty, not connected, or needs to be replaced

It may indicate the thermocouple failed. If you can short the lead wires
from the thermocouple this message may go away. By short I mean touch the
leads together some where below the actual junction of the thermocouple which
is inside the kiln. Use a pair of pliers,make sure the connection is clean
may have to scrape it.

Hi Fran,
While I'm not too familiar with the workings of your particular controller, I
would guess it's a thermocouple failure. It could either be a connection in
the lead wire, or more likely, the thermocouple has burned out,. This is
natural and it is considered a wear part that requires periodic replacement.
Remember that a thermocouple has polarity and has only one way to go on
properly (reverse the polarity and the temperarure reading will go down when
heat is applied). If this isn't a modular system that is plug and play, you
should do a quick check to insure that it's attached to the lead wires
properly. A quick test is to heat the thermocouple with a match then check to
make sure it has increased in temperature and is not heading in the wrong
direction. Another way (if this is a "type K" ) is with a magnet. Note which
side is which when removing the old thermocouple. Only one side will be
magnetic. Test the new thermocouple with the magnet and this will show you
the correct orientation. If the thermocouple were transposed it would
probably lead to an additional error message when it appeared that the kiln
wasn't able to maintain the correct temperature rise (usually factory pre-set
somewhere in the ballpark of 18*F/hr increase as a minimum rise accepted
before error is triggered and the kiln shut down for safety reasons)
Hoping that's the fix,
