Look at the burner area, there should be some small round switches with two wires going to each switch. There should be a little round button between the wires, push on this button and see if you feel a little click(like it engaged). These switches will be your flame rollout switches. As far as you limit, it should be located on the wall of the combustion chamber, it will also have two wires going to it. You will either have to test for voltage across this, or do a continuity test on the switch. To test for voltage, there should be 0 volts across swith terminals when there is a call for heat, if there is 24 volts, the limit is bad.

Josh, you just type to fast for me. Lol.

Haha, its not how fast you type, but the quality of the info. Most times slower is better.

The wires at the stat are as follows:

G – green, Y – yellow, W – white, RH – red, jumper from RH to RC

Ok, you don't have a common hooked to stat, but not a problem at this point. Check the limits and rollouts next.

There may be up to 4 role out switches
Both sides of the burner, blower compartmant, and also high by the vent.

Click on the link josh provided to see the rollout swith.

Lee you got this for a few I have to help the wife for I min or so I will be back in 20 minutes or so. Also I was just thinking find out if it is a 80 or 90 % furnace. The pressure switch could be stuck closed. Not very likely but maybe!

Ill stick around for awhile, got to go tend to my family duties soon to. Take care, hear from you tomorrow.

You still around serg? Find anything yet.

It works!

All it was - corroded contact on the limit switch.

Thanks a lot, guys! Now my girls and boys, well, and myself will sleep in a worm house.

Sergei.

Awesome. Glad you got it fixed. Great job. Stay warm and come back any time you need help. Maybe you could give josh a rating, as he is the one that stuck throu this with you. Take care, and once again, good job.

Hi Mygirlsdad77,

I am new to this site. How do you rate the answer/answers? I will be happy to do it for both of you. You’ve been a great help. I would never figure it out on myself.

Once again, thanks for you help.

Sergei.

You just click on the RATE THIS ANSWER box. Its right next to the quote user box at the bottom of every answer. Im not sure if you can rate answers at this time, as they make you have a certain amount of post before you can rate others. Let me know if you can or not. If you cant, its not your fualt, its just the way the system is set up, mostly to prevent negative ratings to pros that have been here for awhile and don't deserve a negative rating for their advice.

Just was reading to see what was going on. Glad you got it fixed, good job. Have a great night!

Josh, just a heads up, you have probably noticed that you can't give certain people a rating. I'm not sure why this is, and I've looked into it on numerouse occasions. It seems that once you have given a rating to someone, you can't give them another rating until you (spread some rep around). I have tried to give you pos ratings, and I get the same answer(need to spread it around). Maybe someday they will fix this(although it is a good idea, since it doesn't allow for people to get two screen names and rate themselves up to a point of perfectness). Just thought I would let you know about this. We all like our ratings(hurts when we get a negative rating, but that's the game here I guess.

Hi Mygirlsdad77 and Josh,

The only boxes to rate the answer I see on the bottom of my own messages and none on the bottom of yours. I guess, not too much I can do at this time. Would be glad to give you both a high rating for helping me in this almost desperate situation – it is going to be -4º C in our city tonight. Not a problem for me …now.

Good job!

Don't worry about it at all. The important things is that you have fixed your problem, and we know that you appreciate our help. Hope you had a great easter.
