ReplyFind a service company, not a duct cleaning company. There could be any number of things wrong with it. A decent service company should be able to figure it out.

After a major remodeling project, I had my air ducts cleaned and a furnace check-up. Nothing reported wrong. Since then, the furnace has failed to fire three times (over two months). I flip the power switch to reset and it fires right up. I had the HVAC firm that did the cleaning and check-up come out the last time it happened, without resetting the unit, and they could not find the cause, stating "since the furnace does not have a diagnostic system, I can't find the reason that it won't fire". This concerns me that a certified technician can't fix a furnace because the furnace can't self diagnose itself. He recommended a new furnace. All of these discussions were with my wife.
The furnace has worked fine for the 6 years we have lived in the house, and it only started acting up after the "cleaning and check-up". Furnace is 14 years old and we believe it had the inductor??replaced in 1995.
Any suggestions on root cause?

Bryant 398A does have light for service and the fault codes are inside the door on bottom..
Most likely door switch if furnace has been working ok..

The company is an HVAC service company that does duct cleaning, not a duct cleaning company. Thanks for no input.
This model does not have dianostic lights and there is no door switch.

Wow Jimbo, if I were a betting man I'd say you just guaranteed yourself a whole lotta silence from anybody here who might have helped you...Originally posted by jimmo

FYI, depending on date of manufacture this furnace could have had diagnostics, and it did certainly have a door switch when it was manufactured. The suggestion to get a furnace repair company was also a good one as whomever you had clean your ducts hasn't got clue one on how to fix it... LMAO when I read they couldn't fix it because it had no little blinky light! Good luck, I suspect you'll be needing it.

The first step, in my step by step trouble shooting, is to have the customer aks any potential Professional HVAC techs in the Boston area sign a legal release saying they do not go by the alias Control_noob or on any HVAC internet forums.
If they do go by that alia, be sure and ask if the attitude and verbal abuse is extra or comes free with the service.

There are few situations that will cause the control to go into a hard lockout.
Did the remodeling project involve the installation of a new digital theremostat for the furnace? Some of the older 398 control boards had "issues" with some digital thermostats, specifically types that use small amounts of the furnaces control power to power them. This small drain of the control power from the furnace will make the board think there's a problem and cause it to lockout. The one I had do this would randomly shutdown. The one constant seemed to be how long between run times. The longer the furnace stayed off between heating cycles the sooner it would lock out.
The other thing that I can think of that would cause random lockouts is if the furnace overheats a certain amount of times compared to how many times it runs. I'm not sure if your control board has this function in it, but experience tells me that the duct cleaning might have included a filter upgrade to a "special" filter that cost you extra.Some of these wonderful, save the world from dust, filters will restrict the airflow on the furnace to the point where the furnace's high limit will trip.
Good luck.
Gremlins do exist!!!!! They live in furnaces in the winter and air conditioners in the summer.
