senior tech...point under consideration

As a service manager of three other Tech's my advice is always don't get impatient. Remember Rome was not built in a day, just remeber and realize you are never done learning. I learn somthing new...

Go to the Coleman/York supply house and pick up a remote flame sense kit and the new ignition module (all in one kit), and I promise the problem will go away. Not a real difficult installation...

do you happen to have the model# of the furnace? Some of the older coleman furnaces required a special adaptor to pick up the flame current. Are you sure that the flame sensor is not tied to the...

Out of curiosity, what is the outdoor temperature when all this strange stuff is going on? Then also what is the balance point setting at? Could it possibly be that the outdoor temp is below the...

Have had a similar problem with some Trane furnaces, have switched to stainless burners, and the problem has went away. Not saying it will solve your problem but it might be worth considering.

Firtly, it is a 100k btu furnace just a typo on my part.
Temp. rise was at 56 when measured the other day, as for model number set it out today at the office to post but never had time to post it,...

Robo...homeowner made that offer, but never took them up on it. Was hoping maybe you have some similar case and could give any insight on what maybe I have not checked already.

Yes, and to no avail. I really beleive that there has been virtually no stone left unturned on this furnace. My only other thought might be along the lines of whether a secondary heat exchanger...

I agree it could be any one of the above, but usually when a furnace is rolling out like that it is searching for oxygen to burn. I have had baffles get plugged at the top of the exchanger causing...

Trap was leaking upon first trip out so it has already been replaced, but nice thought.

Its an 80pk-8

I have never seen a mist humidifier work properly yet. I agree they make a good way of cooling of in the summer thats about it.

It's back! I have a 90% Goodman furnace that has a problem I simply have not been able to figure out. It started last winter, and now has resurfaced again this year.
I will start from the...

I can see two sides to this question, zoning can be installed for comfort but also can see where if used properly could save you money. Let me ask you a question about how you intend to operate your...

Hey I agree with Mark, had a very similar situation just last month, and I had a electrical contractor check the connections at the service mast. It turned out they were loose, he tightened and the...

I do not believe that Mark is correct, if indeed your dip switches are set correctly as you stated. Even if w3 is being energized you would still only get 1400 CFM not 1800. This is an interesting...

Good question. Both are essentially the same thing. They bypass air from the supply back to the return. There are varying degrees of thought as to whether it necessary to do this. Some...

A question for you guys. Does anyone have a good way of checking cfm at a supply register, and be accurate? This is in a residential application. We have used a hood and have used a tif va105, but...

Wolfdog....Thanks for all the help, but one further question.I found some more information from Trane, they write in their literature that a 72 Kw heat strip package @ 460 3 phase requires a max fuse...

fuse is sized times 125%, and you would not divide by three....i think.

Wolfdog a formula would be helpful. I just now read your reply in the pro forum, how did you arrive at a 100 amp fuse. I have come up with a 125 max fuse size as the mac is rated at 122 by my...

I have a question for somebody out there. If you have a 72kw electric heat strip package on a 460v three phase service what is your max fuse size, and the next question is how do you figure it. I...

It depends...there are more factors than just the ambient outdoor temperature. Would need some more info than what you have provided to completly answer your question.

Tom, Carrier serial numbers with only seven digits were made before 1970, the first digit #6 tells me it was made in 1966. For your own info if it had a one it was made in 1961, a 2 1962 and so...

One thing I failed to mention the amp draw reading on the secondary side was @5.4amps, before I repaired the shorted wiring. Somebody correct me if I am wrong but the fuse on the circuit board is...

As a student and always trying to learn I have a question for you guys.
I was working on a Trane furnace TUD080R, and upon arrival I found a bad XFMR with an open primary side. I inspected furnace...

hey Doc, I had a similar set up in my boss's home with a vs furn and no by-pass, and we had problems with it until we installed the bypass. Since we have done that work we have no problems. I too...

David what was the intial service call...no heat? What is the age of the furnace? Anytime I see Janitrol associated I have to think heat exchanger, but I have been wrong...even once today(just...

very interesting, have worked on many other cozy products over the years, and have all been built resonably well. Will have to keep my eyes open for these out in the field. Thanks for the info.

lennox has its extended warranty through a company called complete care plus. look up davenet.com and they have a phone # listed there and maybe they can help.

sorry david just read the post...disregard the propane questions, but am curious as to what the other readings were?

david quick question...you said you looked at the compression rings on the heat exchanger, but what about inside of it? Have you checked your vent with a magnehelic guage? If so what are your...

yep...lennox has it.

I will agree totally with beenthere. If that is what you have been told time to find a new contractor.

cityboy, where are you located? I know a company called Glassfos makes the stuff you are talking about but I am not sure where you are located as to where to tell you to try.

Currently GE is the only manufactuer of ecm motors so no matter who you buy Carrier, Trane York it is virtually the same motor, the only difference in my understanding is the controller might...

For whatever it is worth, I could not agree more with what everybody else has posted. VS is with ou a doubt worth the money, and adds to the comfort level of the home. I would pay retail in a heart...

could it be these are some of the least understood units on the market? the trane 19i which i sell is a complicated piece of equipment with a whole lot of bells and whistles. the rheem and ruud...

it is very possible that what they tell you is true, and yes it could very well cost that much. I think if i was you i would spend the extra money and get a second opinion. You never know a service...

yes...consider it done.and please accept my apologies.

TO ANSWER YOUR QUESTION, IT WOULD SHUT DOWN, IT ACTS JUST LIKE A HIGH LIMIT IN A FURNACE. IF THE TEMPERATURE EXCEEDS THAT 130 SETTING IT WILL SHUT IT DOWN. TO ANSWER YOUR OTHER QUESTION IT VERY WELL...

VSCHLITZ
I AM QUESTIONING WHETHER 130 IS ENOUGH. TRY SOMTHING FOR ME, AND CYCLE YOU ELECTRIC HEAT ON EMERGENCY AND SEE HOW LONG IT WILL RUN, OR SEE IF IT CYCLES OFF BEFORE THE STAT IS SATISFIED. IF...

Let me ask you a question, do they have a supply air sensor in use on your uzc3 zone control, if you are wondering upper right hand corner of the zone panel there is two terminals maked sa1...

I agree with phosgene, Carrier makes a great duel fuel stat. Best of all it is not to difficult to install. What brand of equipment are you getting ready to work on? It seems to me everybody does...

A word of warning to the wise, stay clear of the honeywell steam humidifier, the elemnts fail far too often. It has been my experience that they fail every year. I like the Apriaire powered...
