I have a Goodman Gas Furnace installed in 1997 and have been experiencing the following problems:

The usual run for the furnace has been inducer motor on, ignition (with flames), and then the blower motor comes on.

I have been having the inducer motor come on, run for about three minutes, shut off, turn on again then ignition OR the inducer motor comes on, runs for about three minutes, shuts off, turns on again, shuts off, turns on again and then finally ignites. I have even counted the number of times that the inducer motor has come on and it has taken place after the fourth shut off.

In the last three months I have done the following:
1. Replaced the blower motor (due to a strong burning smell from it)
2. Replaced the capacitator
3. Replace the flame sensor
4. Had the condescant (spelling?) pump tubing and trap blown out

And the problem continues...

They are now telling me it is either the "board" or the thermostate... any suggestions?
We have also had loose tubing on the pressure switch tubing between the inducer motor and the other part (I do now know what it is called).

Also, should the furnace "lock out" after the third try of the inducer motor coming on and then shutting off?

OK its not th ethermostat as your circuit is complete you are getting ignition. Now Do you have an his (hot surface ignitor) a big bar that glows orange to ignite the gas?

As for the furnace going into lock out after three tries that's normal

Look for a clear plug with a red LED inside-you may have to move around a bit to see it through the plug as there are probably some wires in the way. If this light blinks when the unit runs, it is telling you something. See service label for translation.

The question is nearly 2 year old,, I hope its fixed by now
