Weathermaker 8000 ts won't start
 
Thank you in advance.

I have a Weathermaker 8000 Two Speed furnace that does not always start. If I turn the "master" switch on the side of the furnace off for a second or two and then turn it back on the system works correctly for various lenghts of time (4 to 18 hours). I do notice a quiet hum from the furnace before I turn off the "master". I would like to get an idea of what the problem is and do what ever trouble shooting I can before I bring a tech in for repair. Any help would be appreciated. (I went to the Carrier website for help but found it lacking in customer support.)

TY

Hi WM800ts

It sounds like the furnace has not been serviced in a while. It more than likely just needs the flame sensor pulled and cleaned. When you shut the service switch off on the side of the furnace you are just resetting the lockout. When it does its thing if you will look through the plastic window on the front of the blower panel you will see a flashing red light. It will flash fast and then slow. Count the fast then the slow, the fast flash is the first digit in the error code, the slow flash is the second. If you can give me the code I can tell you exactly what is wrong with your furnace. But I am betting on a dirty flame sensor.

Good luck
Rusty

Rusty,

Back at home. Error code 1-4 which refers to 3-4. Have 600 grit sandpaper. I'll see if I can clean this up. Please let me know your thoughts.

Hi WM8000ts

Stop!, Don't use sandpaper of any sort on this rod. It leaves a silica dust and scratches in the rod. At this point you have ruined the rod. Use a wire brush or steel wool or something of that equivalence. Let me know if I can help further

Good luck
Rusty

Rusty,

To late. It did have carbon or something on it. It did clean up nicely. I also used a damp cloth to make sure there was not any "dust". After restart the system as restarted twice. In the event I need to replace the rod are they easy to find and purchase?

Thank you.

Wish I would have seen your message before hand. Wouldn't a brush or steel wool leave some scratching in it too?

Hi WM8000ts

The flame sensor is a stainless steel rod, the wire brush is either going to be brass or a mild steel. Neither the wire brush or the steel wool has a detrimental effect on the rod. Sorry I did not catch you in time to stop you.

I have been using emry cloth to clean flame sensors for years and I have never had a call back, nor have I ever "ruined" a flame sensor doing it.

Hi acefurnacefixer

I have been doing this for a year or two myself, we were told by our factory representative. If we use sandcloth or any sort of silica based abrasive on the flame sensor and it fails under warranty, we know own a peice of glass covered stainless. I know they are not all that exspensive, but if you take 9300 customers and have to replace them at your own exspense, that is expensive. Carrier corporation will not under any circumstances warranty a flame rod that has had sandcloth used on it. That is why I do not reccomend this method, not that it doesn't work, it is what it does.

What are you talking about? You think they look at every flame sensor that comes back? Come on man.......it would cost them a small fortune to inspect a part that cost them pennies.

I have been sanding flame sensors since the very first furnace with a flame sensor came out back in the early 80's and never ruined one nor has carrier or any other manufacturer rejected a warrenty claim made by us.

Instead of worrying these people to death over a 2 dollar part, focus them on yearly maintance so they dont have to worry about silica dust on a friggen flame sensor. I dont know how long you have been a technician, or if you even are one. Maybe you just stayed at a holiday inn exspress last night. Any experenced tech will tell you that cleaning a flame sensor with sand cloth is ok.

There is a huge difference between what the enginers say SHOULD work or not work, and real life in our industry.

Hi acefurnacefixer

I am happy for you not having any trouble with this method. Look at my profile and you will see why my advise apparently sucks to you. I guess being a toilet scrubber isn't as glamourous as being a technician. But as long as I am the head toilet scrubber at my company. We will do it the way we have been doing it. Once again the conversation has gone away from the question of the original post. I have said all I will and I bid you good day.

I find it odd that you say "Carrier corporation will not under any circumstances warranty a flame rod that has had sandcloth used on it."

And yet the very same "Carrier corp" does in fact warrenty flame sensors that have been sanded, been burnt up (LP GAS) been broken, been bent ect ect. Also you say "Stop!, Don't use sandpaper of any sort on this rod. It leaves a silica dust and scratches in the rod. At this point you have ruined the rod.", and in fact this is a daily practice of thousands of techs all over the world with no ill affects at all.

The point is just coz some field rep who pushes a pencil all day long says something to some young green tech, dont mean that its right.

You made vm8000ts think he ruined a part on his furnace, and he did no such thing. In the eyes of thousands of techs he did the RIGHT THING. Think before you speak, or have better advise on the subject at hand.

I never said your advise sucks, but its certianly NOT correct.

Apologize to carrierman.

You have shown little respect to someone who has taken the time and energy to help us.

We need him back.
So please get him back :yes:

I wish I had seen this going on in time, We will not tolerate personal attacks of ank kind on this forum. I don't have a problem with a technical disagreement, but posting negative comments on a post to "prove" something will not be allowed.
