is this normal or do these guys just not know what they are doing???

[seesh]

Just had my furnace replaced and it turned into a day and half job...

Installed a single stage carrier 58MXB60.

The install was appearing to go pretty smoothly until everything was hooked up and the furnace wasn't firing up.

Long story short, they tried replacing the board and then the actual gas valve. Both "fixes" didn't do a thing. The next day they came back and told me my humidifier (run of the mill tray type) was the problem. Sure enough they unhooked it from the furnace and the furnace started working. Something to do with the voltage of the humidifier.

Just wondering how common this is because these guys were baffled?


Onto the next problem...

I had to make these guys ensure my AC still worked...sure enough now my AC didn't work. They pretty much started blaming the thermostat (run of the mill programmable thermostat that had been working fine before the install).

They installed a new thermostat and then everything started working.

Any idea how a functioning generic thermostat just stops working? Is this common with new furnace installs?

humidifier should be on a saperate transformer. They can cause problems with circut boards

it is possible for the stat to go bad for no reason but in this case i tend to think the humidifier may have wiped out the stat.

if the motor on the humidifier is shorted or drawing to much va then it can in fact cause a lot of harm to all system components

Thanks for the info.

...I'm no expert but the stat didn't appear to be fried. It still allowed me to turn on the heat. The two things that didn't work were turning the fan on and the AC. So maybe it partially failed??

Depending on humidifier can cause resistance and harm or even blow board. Carrier has had some problems with humidifier tied into HUM terminal which also power gas valve and if the VA is to low gas valve won't open. Thermostat could be many variables too many to talk about.

Sounds like they hooked the humidifier up wrong, which shorted out the t-stat cooling circiut. if they fixed it on their dime, i would be fine with it. did they fix the humidifier?

Well they didn't fix it...yet...They want to sell me a new one of course (Aprilaire 600), installed on their dime. Just not too impressed so far and don't know if I want to deal with them any further. Although, I assume a humidifier install can't be that complicated.

Seems like, they're at least trying to work with you on this. Don't get angry just yet. Give 'em another shot.

You never answered the question? if it is a flow through humidifier or a april air 600 you can wire it upto board. That is what them terminals are for. If it is a drum piece of junk, then you have to install a transformer and wire it off eac1 and eac2 piece of cake. If they do not know that I would be seeking help somewhere else.

my functioning cell phone quit on me yesterday :confused: it is only 2 months old, i haven't even dropped it good yet :mad:

you see that too :)

[skwsproul]

Strange things can and do happen in the hvac world. If they are working with you, then they care about their customers. Even the most experienced techs make simple mistakes. I will not say give them another chance but let them complete the chance that you have given them and I would even go so far as to say you should recommend them to others. How many auto mechs will take care of the problem without making up some bologne that the part went bad due to another component and turn around and charge you more. These guys may be covering their rear a little, how can you blame them, every time we turn around we get blamed of something that is totally unrelated.

I've seen quite a few of the Home Depot/ Lowe's generic stats go bad. Is that where it came from? They're just not a quality item. No offense intended.

Well it was a "drum piece of junk" which they wired straight to the board without a transformer. Wouldn't this be something I should expect the tech to know? They did work hard to try and resolve it so the effort was there, but there is just the issue of competency.

I can tell you when I had my Infinity furnace installed I kept my current humidifier (aprilaire 700A) and it did not work when they wired it into the bd, but what they did have to do was get some sort of transformer type part they had to wire inbetween the humidifer and the bd to get it to work right as they suggested I have it wired to run only when the furnace kick in and not when I needed humidifacation so I was told to try it that way for awhile. The part they needed was alittle black box was small maybe 1"X 2" and about 3/4" high. They had to use the same part on my dad's furnace too. It could be fixed now by Carrier since we had our furnace's installed but can't say for certainty.

[m kilgore]

Well, I wouldn't throw them under the bus just yet. It seems like they are trying to work with you on the problems that are comming up and that can be rare in this or any other business lately. It seems very few compamies of any sort care about customer service anymore.

The problem with your humidifier may or may not have been known to them. Not every tech has seen every problem and might need to start from scratch to resolve the problem. A 600 installed on there dime. I would do it and get rid of the peice of junk you have.

Not everything is writen in stone and this company is trying to work with you. As said I would even go as far as recommending them as they seem to care about what they are doing from what you have told us.:rolleyes:

[21degrees]

[QUOTE=DanW13;2004683]

Then you would wire it up to board, I do not know why you would have problems wiring up to board with flow through, that is the proper way to wire it a strong recommendation with infinity controller. Just becareful not to short wires out. Why do you think the manufacture puts them there?:rolleyes:

[DanW13]

I have the Infinity controller, for some reason they had to put this little black transformer of sorts between the humidifer and the bd. I didn't ask any questions of why they needed it.

[21degrees]

[QUOTE=DanW13;2004968]
Do you have a seperat humidistat for Humidity or is it done through Infinity controller.:confused:

[DanW13]

No, they had to do this to my dad's to he has the same furnace and the newer model of my humidifer and they also had to install this. I guess they checked with the warehouse where they get there equipment form and he's the one who told them they needed to add it.

Rh-Rc in old stat??

only Rh tied into new furnace...........:cool:

Colemans don't need no thermostat

[agit8er]

It's called an isolation relay. The hum and com terminal on an Infinity board produces 24 v. Some humidifiers provide their own 24v by way of a transformer in the humidifier housing. All of this is common knowledge among qualified installers. The Aprilaire install book is very clear concerning the installation of an isolation relay whenever installing these style humidifiers to "hot" 24v terminals. Even the best installers need to read the install books now and again! At four to five dollars a gallon, sometimes it is better to be humbled by reading the install guide on the initial trip than getting that dreaded "call back".

You are totally right on that, but how do you know its not transformer.

That's a fact. It's amazing the information those little books contain.

sorry to say it is a common mistake. Most times there are no problems to speel of may cause trickle affect to the flame semser and cause lock outs for no reason

if the motor is weak and draws to much current then more serious things happen.

they seemed to be trying and as far as selling you a new one well thruth is you need it and thay made a simple mistake and arent covering it up

i realy dont see the concern

[QUOTE=tinknocker service tech;2006056][quote=seesh;2004677]


Something about flame sensor, Nothing do do with flame sensor. Selanoid valves usually don't steel power, where motors do. It is wrong to hook a drum humidifier up to a board, it is not wrong to hook up a selanoid valve like on the flow through. These guys should no that you would think.;) The hum terminal is the same power as gas valve and that is where you can potentialy have problems with flow through if wires are shorted out.
