I have a Lennox G23Q3/4-100-2. The unit can work fine half

Customer Question

Hi, I have a Lennox G23Q3/4-100-2. The unit can work fine half the time. Sometimes when the blower kicks on the flames dont kick in and it just blows cold air. Usually if we shut it off and wait about a half hour it will kick back on with heat. If we turn it on too soon it still blows cold. Sometimes the longer wait doesnt work. Thoughts?
JA: Sometimes, Lennox G23Q3/4-100-2, HVAC issues that that you think will be really complicated end up being easy to fix. The HVAC Technician I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the HVAC Technician should know?
Customer: no
JA: Our top HVAC Technician is ready to take your case. Just pay the $5 fully refundable deposit and I'll fill the HVAC Technician in on everything we've discussed. You can go back and forth with the HVAC Technician until you're 100% satisfied. We guarantee it.

Have you noticed what the LED sequence on the control board is when the unit acts up?

I was told that it was a $5 deposit. I was charged $28. I was looking for one question not a subscription.
