, posted Mon 3 Mar 18:01  
LENNOX furnace, 2.5 years old.
Igniter failed to work after Thermostat called for heating. The fan ran several minutes and then stops. The diagnosis code is “slow flash” for both lights.
It was less than -30 degree that day, and we called a guy to come in for repairing. He claimed that it is the igniter’s problem, and changed a new one. However, no thing happened after reinstallation. He asked us to leave because it is uncomfortable to work while someone stands behind you. We felt sorry and left him there for 20 mins. Furnace worked. We paid $650 for the repairing. We signed the invoice which shows it is igniter’s problem and igniter was changed.
28 days later, some problem happened. Because there is a 90 days guarantee, we called that company again. Some guy came in and said some thing. However, three igniters were changed, did not work. He spent an hour there, and then told us it is the circuit board problem. Nothing related to the previous repairing. We have to pay every cost occurred during this repairing. We have to pay $860 for the circuit board.
We want to know what’s happening there, but he did not want to tell us what he did after failure of replacing the igniter last time.
We refused to go further for processing because we did not have any confidences with him. However, we were pushed to pay him $135 for his coming. After he left, we checked the furnace: pressure switch is loosed without screwed on the metal board. The diagnosis code became “left: OFF, right: slow flash”.
Now, after having paid around $800, our home temperature is around 3 degrees. We are praying the weather will not go wild to -30 again, and our two daughters will not be so suffered.
Anyone has any clue what was happening to our furnace? Is that guy innocent? Should we follow his instruction to change the circuit board?
Thanks,
sun

Yuri is right about the guy ripping you off. I also have had one igniter in a Lennox furnace. We need the model and serial#s off the furnace. If you remove the top panel of the furnace the model# is at the bottom. Here are the diagnostic codes, watch them and give us the codes.

When this happens does the house reach the temp or does this code happen before it reaches the temp.

There is no heating. So I turned off the Thermostat. After I turned on the Thermostat and adjusted the Thermostat to a higher degree (like 26 degree), then, fan runs with blowing cool air into rooms for a couple of mins (both light fast flash now). then automtically turned off itself(left OFF, right slow flash).

Make sure the thermostat fan position is set in the auto position. If you put the thermostat heat up the first thing that should happen is the small fan that pushes the exhaust up the chimney should come on.
Then if you listen closely you will hear the pressure switch close.
Then the igniter will glow.
Then you will hear another click from the gas valve letting the gas flow and then flame and then the main blower will come on.

We do put the thermstat at Auto position. The thing is that air inducer works after thermstat call heating when requested temp is higher than current temp in home. However, igniter did not go orange and there is no flame.
Remember that guy showed me, when removing the igniter from the connection, the voltage between the two opened ends is around 110 and once connected igniter back to there, the voltage dropped to very lower (appr. 0). He claimed this shows the circuit borad is failed.

You may try the Lennox district manager for Calgary. Lennox has a large plant in Calgary or Edmonton and a good presence there. I lived in Calgary 5 yrs ago. With it booming like crazy it made be hard to get satisfaction from them but it is worth a try. They may accuse you of tampering with it now and try ignore you. Try get them to explain why you could fix it and not the tech. Both Marchvac and myself are professional Lennox techs/dealer so show them or print Marchvac's comments. Lennox hates bad publicity so maybe they can pressure the tech if he is a Lennox dealer. If not you may be out of luck. Consider yourself fortunate he didn't do some serious damage. I went and did a service call and missed out on the fun.
Pay it forward. Help someone else with your skills. Glad you got it going.

I may try, but who knows. Anyway, it is good our home is warming now.
I would post the guy's company here: KNIGHT PLUMBING and HEATING. Wish no more victims!
Thank you again!

So if I understand you correctly the small exhaust fan is coming on. Between the small fan and the pressure switch is a rubber tube. Disconnect it and make sure that the tube is clear. Also get a paper clip and make sure the nipple on the motor is clear. You can blow into the tube when it is on the motor but never blow into it when it is on the pressure switch. If that doesn't work it could be a plugged chimney or the pressure switch is not working correctly.

This suggestion just brought heat back to my house for FREE as well. OK, almost free. I need to replace the tube from the motor to the pressure switch as it was cracked on one end. I did have a gorilla tech install the thing and "fix" the very same problem. In fact, the paper clip was still laying on the inside of the unit.
I am assuming I can use any high grade automotive tubing? That's what I got from the garage to make it work and was just planning on leaving it. It's nylon re-enforced "collapse proof" rubber tubing.
THANKS!

You need high temp silicon tubing or the end will melt/crack at the inducer motor.

I am a Professional Lennox tech and have had VERY VERY few problems with their igniters. Lennox invented that system and it is the best on the market. You need to call an honest reputable Lennox dealer to check that unit. If it is blowing igniters then you probably have a poorly grounded furnace or other voltage related issue. Most Lennox units have a 5 yr parts warranty so I suspect this guy is ripping you off. Post the model # and serial # as I am curious as to which one it is. Where in Canada are you/which city? Your local Lennox district rep may be able to help you if this guy is a bum. They stand behind their product/reputation very well. I may be gone for tonite (on Call).
Good Luck
Yuri

Following the instruction from Mr. "MARCHVAC", our furnace works again now!
Thanks for your reply!
By the way, do you know how we can find someone who may help us since that guy really cheated us? Maybe we just need to pray for him! I do not really know and just confused that why people are so different! while your guys are trying to help people, the others are trying to cheat for money.

I think the tech may be very inexperienced and is what we call a "parts changer". That is why he was very uncomfortable with you watching him. Perhaps his boss will be reasonable and adjust the billing now that the problem is solved. Wait a day or two to make sure it really is solved. See my reply (6) or more above this one. Try be reasonable with them and maybe they will help you.

I will. May be he is only new. I noticed that during his stay, he called his manager(he said) a couple of times, to discuss something for a long times.

I checked the manual, and only found: G40UH(X series) on the cover. Is this the info. you asked? where I can find the model # and serial #?
BY the way, that guy changed three times of the igniter. And then showed me the igniters actually are good by connectted them into one plugin on the wall. So, it should not the grounding problem?
