Hi

I have a Trane "Gas-Fired Fan Assisted Combustion System" with
"Intelli-Ignite" home furnace (model TDE060A936KZ) that I believe is
reporting a false "Open High Limit Device" error. It will operate just
fine for days then suddenly report this error and refuse to ignite. It
may choose to do this upon startup in the AM while completely cold;
having been idle all night.

The reason I believe it's a false indication is that while it was
reporting the error I checked each sensor to see if was open and they
all reported closed. Also, usually, simply cycling the breaker for the
unit will cause it to resume normal operation.

The filter is clean and there is ample air-flow.

So the suspect now is the control board. Are there diagnostics that
can be run on these boards? Is this common for a board to just
malfunction like so? Is there a reset procedure?

Thanks.

Brian

Yes, you need the Electronic Board Tester by Trane. It will tell you exactly
what is wrong with your furnace.

Part # BAY07843-A

Its $375 at the local Trane supply house. Where are you located?

You can also use the Goodman board tester for the Trane boards. You just
have to redo the connector to adapt to the trane connections (common parts
from Radio Shack). Also, the fault codes have to be corrected dividing the
result by .30 and then adding "2".

I've got the Goodman board tester V.6.23, but any of them above V.4 or
higher should work fine on the Trane boards. Mine was ~$42 at the Goodman
supply house last year.

I've had terrific success with the Ford Pinto Combustion Module
Tester. About $12.99 at Auto Zone. Of course, I had to solder all
new multipin connnectors on. Which was no problem, cause the guy
wasn't using the multipin connectors at the moment cause I had
the board out.

Divide by 0.30 and then add 2. I had to do much the same.
