Trane open high limit

[bsheeres]

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.

Yea, things tend to report errors till they are reset.

Are you sure? Do you test it? If so, how?

Why can&#39;t it be a problem due to "lack of maintenence" or an "installation issue"?

Sure, how much money you want to spent to test it?

Not likely.

Yes

Your welcome

I&#39;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&#39;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.

The guy asked for help, I offered a guess at what I think the cause is given his diagnostic. If he&#39;s dumb enough to do something he&#39;s not confident doing then o well.

This isn&#39;t rocket science. No offence.
