Furnace Control Board Installation?
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. -- MattMika |

So you get a warranty and labor for about $130, plus you get it done right and today rather than with the possibility of issues and some time in the future? I like to do things myself when possible, but that doesn't sound like a bad deal to me. JMHO, of course. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam.

Parts dont usually fail in pairs. THEY CAN but not usually. You may want to question him why it needs a new board. You may wish to wait and see if the pressure switch alone takes care of it. Id wait and see or get another opinion. You can always get and install the board yourself but as already stated, you'll get no warranty and you may not even need it. Good Luck Bubba |

Good Luck Bubba Hi, Pressure switch is very easy to test. It's simple on/off switch triggered by diaphragm at certain pressure range. There just could be some dirt or even drops of water in the air hose. The control board is based on sequential logic. I went thru whole thing on my Carrier furnace just before winter. What kind of error code were you getting? This will give a clue to the cause of the trouble. Lot of times, vibration and heat causes cracked solder joints on board. If you really have bad board, it's easy to replace it by just moving wire harness, plugs one at a time in parallel after turning off power. Some boards are not exact replacement. It cocmes with instruction and wiring adapters, etc. In my case, high Watt resistors on board had poor cooling under the plastic cover and the excess heat caused solder joint crack. I reinforced the joints and drilled a few holes on the cover for more air circulation. Now we're in dead winter and furnace has been working just fine. BTW, error code I was getting was pressure switch(which does not mean it is bad. Just it's a clue. Start trouble-shooting from there. As a retired EE(from Honeywell) I am surprised some HVAC people has very minimal knowledge of electronics. They create lots of wasted time and material. Tony |

Furnace Control Board Installation?
Thanks to all that have replied and will.
During my lunch break I went home and turned the furnace on and off as many times as I could in an hour and the furnace never failed to fire. I decided to call and cancel the control board install. If it starts acting up again I can call them back or do it myself, I'll decide which route when and if the time comes. -- MattMika |

Furnace Control Board Installation?
Same thing has been happening with me.., hate to have numb-nuts service
kid come out and charge $300 bucks for a small little bread-board thing'y. But, also hate fall'n off the g'dm roof at 66 years of age..!! I think Tony forgot to mention little red light on the board which "blinks" and gives the "codes". If it's steady on, then the board is okay.., if it blinks a number of times, then it does have a problem. Another thing, if you order an electronic part.., you can't usually return it.., I think.., got'a watch for that!! The part I need is the Spark Igniter.., which is $200 dollars alone.., plus the service call.., but then I would have the warranty..!! Sooo, what'a gon'a do..??!! |

Its the "if you were qualified to properly diagnose the board you could save about $90" code. |
