I think its safe to say the furnace is not putting out CO. Ill keep the CO detector in action over the winter just in case, but I think my furnace just needed the flame sensor cleaned.

Thanks guys, if I can ever help with some car advice, I owe you one.

Sorry to inform you but you didn't prove anything. You have an old detector that by now has a weak sensor. And just to further educate you, even a good detector won't alarm until dangerous level are present for an extended period of time. They are made that way because the first detectors would give nuisance alarms. That means that they were going off when the lowest levels of CO that occur in homes from cooking, furnace start up and water heater start up chimney spillage.

You got a bum detector and an even worse furnace and you won't have a chance when one of those heat exchanger cells opens like a clam shell.

I just hope I am not watching the WXYZ news and they mention Monoxide deaths in Plymouth.

That is so incredibly true. Once you have seen flames rolling out the front of one of them you will take this issue seriously. They can split wide open in a hurry. Not worth compromising your familiy's safety and health.

This thread should have been killed because by leaving it DIYs will take it as Cart`Blanch to do the same. They're gonna assume that if the site admin didn't think it dangerous enough to delete there is no threat hazard.

NICE GOING ADMIN!

I think most intelligent people will trust the Pro's advice and do the right thing. The buck savers won't. You can lead a horse to water but you cannot make em drink.

We have an old saying from the old country "You can put BaBa in the yoke but she won't plow."

I think think it's the same in Ukraine?

I dont see how I can respond any further without pissing anyone off.

What can I expect when I show a photo of a good condition heat exchanger? That it will in time go? Isnt that something that can happen to anyones furnace at any time?

I understand you telling me that the unit it prone to failure, heck I know lots of vehicles that are known for problems, but I dont tell the customer to buy a new one.

Is it a matter of saving a buck? No... I have already requested prices for a newer unit with no $$ figures. I am also considering purchasing a wood burner too. Ive installed a CO detector and thats not good enough.

I thank you for the help, my issues were resolved.

SellC,

As a fellow parent, I implore you to spend a few bucks just to have someone come out and check that for you. Children, the elderly and pets are most susceptible to CO Poisoning and will show symptoms and become affected by CO much more quickly then someone who is in the prime of life and healthy. I want to say the estimated life expectancy of a CO detector is about 3-5 years. Especially since you had it in the garage, the sensor repeatedly was exposed to CO reducing its effeciency and not making it reliable. Worst case they find you need a new furnace, best case they give you the green light and say all is well and you are good for yet another season. I am in no way trying to call you cheap...believe me we all need to watch our pennies in this economy, but I know I would certainly sleep better know the very device protecting my family from the cold was keeping the air inside our home free of Carbon Monoxide. Please let us know.

decent of you to make a good case. Regretfully we see the personality type in question all to often in the hvac profession. They like to stir things up for reasons only they know. Perhaps the OP finds glee in getting a rise out of people. Or they are just throw out lines just to see who bites.
Seems to me the more emotionally charged responses the OP gets the more happy he becomes.

If not than why would he still be lurking in the background when he said he was done.

Not very scrupulous behavior.

Now I am a lurker?

You do know I do get an e-mail every time someone replies, dont you?

You speak of my personality, yet you are the one with a vampire for an avatar. HVACLover, do you make it a practice of selling people a new furnace under the pretence that it "Could go any day" or "On its last legs"?

In the automotive business we are not permitted to use scare tactics to up-sell jobs, and if the part isnt BROKEN we cant replace it, unless the customers request to do so. Maybe when someone comes in for a tune up tomorrow I can sell them an engine, because it could go any day.

Sir: your low shots mean nothing to me. If you knew my name you would recognize my company and would not make unfounded ethics accusations.

I question your judgment in assuming a piece of equipment is in fine shape because your ineffective monoxide detector did not go off in lieu of a professional check of your furnace. You have been counseled by life long pros who know your brand and model as well as technically possible.
You brushed off the advice. If you come to DIY sites that have pros to answer questions you will get the answer to your query but do not shoot the messenger if you get advice that indicates you may have a bad unit.

Save the insolence and just get your furnace checked to ensure your safety.

That is all anyone is saying.

How much does a unit my size sell for if I wanted to purchase a new furnace and install it myself?

Now explain to me how the "Family" can be in danger when my CO detector is not detecting any CO? You claim now my CO detector isnt accurate, yet just pulling a vehicle in my garage trips the alarm. Isnt the danger of a broken heat exchanger the CO? If thats the case, wouldnt levels of CO be considered to be "Safe" by any sane person whom had a CO detector?

I will be keeping a close eye on my furnace. I think I would just buy a new one before I paid to have someone inspect it.

Are you truly concerned for my safety? Or are you just pissed off I dodged a bullet this time? How upset are you going to be if I install a new furnace? What will be wrong with that one? Oh I forgot, I am not a "Pro". That means I am just some idiot trying to save a buck.

HVACLover makes it really hard for a guy to say thanks, even if it wasnt directed at him.

So, once agian, Thanks Guys.

You are exposing it, the sensor, to levels of CO that it was not made to absorb.

As was stated earlier modern detectors will alarm at high levels after a certain duration.

You are pouring more monoxide into your garage with a car running than any furnace. the amount from a vehicle idling would set off a half dead sensor.

I also have a comfortmaker RPJ II but I can't find a heat sensor!? I've looked at the pictures of the other furnace (in this post) and I see what to look for, but I don't have one. I've replaced the thermostat (the old was was junk anyway) and the ignitor (it's on port 2 and heats up before the gas starts so the gas will ignite). I'm not a furnace guy, but I'd like to figure this one out. Any help on where the flame sensor is would be appreciated! I'll post pictures later today as I'm running late for church

SELLC was right! His advice and discussion totally saved me money. I was annoyed by HVACLover's alarmist conversations with SELLC when the only problem with my Comfortmaker Furnace was a dirty heat probe. I just sanded it down and the house is as warm as apple pie.

For those that will benefit: remove the burner plate by unscrewing the 10? screws. Find the wire that leads to the back left of the unit. That is the flame/heat probe that is held in place by a flat head screw. Get a long screwdriver and then pull out the probe and sand it down.

The project takes longer to search on the internet than to actually do!

yea SELLC! Keep up the postings and the sharing of information - It's what makes the internet great!
