Nordyne Circuit Control Board 624591-C issues?
hello all,
My gas furnaces been acting up lately. It's been running and shutting off. I notice when I tap on the control board it starts up then shuts off again. I checked all the wires and they seem tight. Can it be something else that I'm missing here or do I need to replace the board? Thanks for any advice or help.

It sounds like a cracked solder connection on the back is the board.
I would replace the board but I have had customers choose to solder the connection.

If you haven't already, remove and replace the wires and connectors one at a time and look for any loose or corroded contacts. Sometimes just removing and reseating the connections will clear up intermittents.

A magnifying glass can be of assistance when inspecting the control board.
Specifically the area that you touch when the fan starts.
Take a close look at the blower connections on your replacement board before ordering it.

last winter I removed and replaced the wires and connectors one by one just like you said and it worked for the whole winter time last year. This year it looks like its having the same issue. I just removed and put the wires back and it seem to be running again. What do you guys think is happening here?

Can you upload a BIG picture of the back to photobucket..... Something like 2-3g. ?
The bigger the better.... I have pic compression to look at it

There are 5 solder joints in a straight line in the lower right for the terminal strip. A couple of them look suspect, especially the one nearest the 9 pin connector.
If you have a low wattage soldering iron and electronics grade solder, I would certainly try touching them up.

Well that's not good. I assume you removed the board to touch up the solder, have you double checked that you got all the wires back on the correct terminals and that everything is connected solidly?
Did you have any trouble fixing the solder joints?
Should not have to reset anything; it's just like a power failure.

The 2 choices included replace the board or try to repair it.
If the 5 amp fuse is still good then replacing the board is still on the table.
Were you able to view my shaky video of a Consolidated furnace before and after blower startup?

Those furnaces have a higher rate of failure than others.
Your looking for flame roll out issues, rusted/clogged/bulging burners.
If you are concerned with the furnace.... have a gas tech come in and check it out. Call your gas supplier. They have good gas techs at reasonable rates.

The flames were blue in the video.
I blow on the flames 2 seconds after the blower starts to show the change in color that can occur if air hits the flames.
You will usually see this in only one or 2 areas when a problem arises.
When you watch the flames burn before the fan turns on it will give you a better idea of what you should continue to see after the fan starts.
That old furnace had a standing pilot and quite a bit of rust on the burners.
I dumped the rust on an old piece of Styrofoam that was near the furnace then poured the rust into a trash bag.

Okay I opened the door and there was the blower but I can't access burners. Theres a panel by the lower area of the burner but when I open it theres no way to get to the burners from there.
