I put in the furnace and a/c myself . When I turn on the thermostat it gurgles at the furnace for a while takes like five to fifteen min to light up and blow is this the norm thanks gary!

Sounds like you may have water in the vent or supply line, depending on the heater, and the inducer fan is blowing through the water. Too much backpressure and the heater will not start. If it is a 90%, it will have plastic supply and vent. Pipes should not have any bow and slope to the outside. This is a fairly common callback if the lines are not sloped properly.

I was checking it out .the light was flashing 3 so the guide said it was the psi switch so I tested that it was good then I got your e mail and I checked the pitch and there was a bow in it and I could here water so I drilled a little whole there and a half of bucket of water came out so I cut the pipes made the pitch right and yahooooooooo thank you so much it works real good now thank you I owe you big time.gary w marchand

I had a goodman installed about 9yrs ago and every yr on the coldest days it will not start. The fan comes on but when it tries to light it just won't. I have had everything in it changed and after a bill for a thousand dollars it still does the same thing. This has been going on every yr since it was installed. I am a single mom and I hate this machine and I would never recommend this to anyone. Any ideas for a fix and has anyone else had these problems.
