So I wake up at 7:30AM (went to bed at 12:00am) and woke up at a house that was 55, normally set to 68...
Here are some pictures/you tube to help figure out what is going on...
After I turned it off and on, it started to work but this is the 2nd time this happened in 1 month...
Please help, Furnace is a bryant and I believe it was installed in 1999.
I don't know if this helps, but after I turned it on and off, the red lights were flashing still, it turned on but it sounded like a belt was bad or something, however after air started going in the vents the sound went awat
Your code is a 21, indicated by the flashes. This indicates a problem that is more in depth than most DIYers should tackle. It needs to be determined if the valve or the control board is faulty. You can check and ensure all the wiring is connected and not chaffed anywhere, between the valve and the board.
They are just suggesting to tap the valve which will sometimes free a sticking valve. If it works, it will get you heat for now, but it is bound to stick again, and will need replacement. But those directions for checking the to see if it is the valve or the control are spot on.
I had a very similar problem with my furnace last year, and it was a defective gas valve. I was not comfortable dealing with that, so I called my furnace guy, he replaced the valve, inspected for cracks / holes in the exchanger (there were none) adjusted the gas / air mix on the burners and cleaned the burners. Furnace works great now. (Well, as well as it has ever worked). -- Gun control is being able to hit your target.
If you cannot get your furnace to restart call your home heating service company and find out if they provide emergency service at no premium cost, many do. Best time to call is during the day although if your furnace will not restart at night they will send a technician out.
Can you see if the Gas valve is a Honeywell one? If so, it is probably a "Smart Valve" one. Well...those are not so smart because a whole lot of them were faulty and would go bad prematurely after a number of years. My Gas Pack furnace had one and it went bad. You could bump it and it would start working but maybe not again on the next cycle. Of course the unit was well outside of any warranty so I had to pony up several hundred bucks for a new valve. Was only charged .5 hour of service call because I diagnosed the problem for them and all the HVAC guy had to do was change it. My unit is from 95 and is still going. It does have electronic ignition instead of pilot light. Google "Smart Valve" and you will see what I am talking about.
Also make sure the fan for the gas exhaust is working. The moisture from the burning gas can cause these to rust or fail. This happened to my neighbor after only 6 years. Fan rusted and broke apart causing unit to overheat in the heat exchanger because the gas was not getting pulled though.
It depends on a lot of things. Are there state/utility/federal rebates to reduce the cost? How efficient is your furnace now and how much would a new furnace save? Normally a new furnace is better but it might also take 6-8 years before it starts saving you money. Most have a life of around 15-20 years.
Personally with it being 19 years old I might repair it now but start saving for a new one. Next time it breaks down get a new one.
I'm going to replace our furnace this year I think. They finally installed gas so we can hook up this Summer. Our furnace is only 9 years old but gas will save us around $2,000 a year. We'll turn a profit after 4-5 years. With the average life of 15-20 that means we'll be saving $20,000-30,000 over its' life. -- What we're saying today is that you're either part of the solution or you're part of the problem. - E.

My house was built in 1989 and since we've bought it I've had the gas valve replaced and the blower motor. I of course have a different model. I plan on replacing it eventually but not for a while. I clean the AC coils usually in the spring and cover it for winter. -- My Blog. Because I desperately need the acknowledgement of others.
My furnace is from 1999, do you think I should keep putting $ into it or replace the gas value only that will cost $400.00
My AC is also about 19 years old, so i think i should maybe replace that too?
My house was built in 1991. The furnace works (only had one part replaced which cost very little) and an A/C unit that quit functioning properly about 5 years ago. There are rebates for replacing the A/C and furnace, which I am going to do (both), but I wanted to be able to reduce my (CC) debt before on replacing both units. I am hoping to do so (God willing) next year. Also, keep in mind when replacing these units they are tax deductible. One other thing, as of 2006 A/C units have switched over to a newer type of freon. So the old supplies will soon be running low and the cost to recharge would be prohibitive. -- Illegal aliens have always been a problem in the United States. Ask any Indian. Robert Orben
