I had a repairman over to look at my furnace yesterday. I was having a problem where the furnace would not light up everytime it kicked on. It would start the flue fan but not release gas or light the ignitor when it failed, other times it would work just fine.
The repairman replaced the pressure switch and said it was working better already but that there was a problem with the control board as well. I decided to just have it done(new control board around $260/1yr warranty), but he didnt have it with him and was supposed to come back today.
I've found the board for $128 online and was wondering if it is very difficult to install(repairman said it was easy, but he gives 1yr warranty).
Should I just cancel the board install and see how it goes and install it myself if it continues to fail or should I just have them do it and get the warranty?
The furnace has not failed to function properly since the pressure switch changeout, but it may just be luck or not enough time for it to have failed yet...
Thanks.
