Need help and/or ideas

We have an older York A/C- gas heat central unit at our house. The heat keeps cutting out and there is a solid red light that comes on and locks it out. When a local repairman comes out, he can reset it and it will work for anywhere from a couple of hours to a week. This past week we had to run the heat at night and even turned the air on a couple of days that it got really warm. Anyway, the repairman is sure we need to replace the controller board, the only problem is, I don't have $300 right now to replace it. Is there someplace online that may have older parts at a little bit of a discount. Also, what are the advantages/disadvantages of using a universal board where a lot of stuff has to be re-wired in order to work properly.

Thanks!

There is some kind failure happening it is probably not the board when it fails again look at the light it should be flahing a code that will tell yo whre to look (flAME failure or pressure switch etc.)

Thanks for the response Mike. That's the thing, the light is solid. Once it is reset, the repairman does everything he can think of to make it fail again so that he can see what is causing it, but he can't get it to fail and the light come back on....that only seems to happen in the middle of the night.
