Rheem classic 90+ burnet flames out

The error reading 13 for loss of flame.

The vacuum/pressure switches work. The inducer motor runs at two speeds & the main blower motor comes on to clear the furnace.

The condensate lines are clear.
The furnace has less than 20 actual heat hours.

Sometimes it will work when the house is in the low 60s & i turn it on. It will modulate the blower speed.
Maybe the gas valve?

The gas furnace is a backup heat source for the heat pump. The heat pump is off when the furnace trys to come on.

None of the local dealers had installed a modulating furnace so i ordered one from the internet & installed it myself. So the locals do not want to mess with it & the warrenty is not accepted.

Any help?
i

it is a common problem! In the five years that i installed this sophisticated unit it happened a few times and it was frustrating to resolve the problem, not the wiring, not the manifold pressure but dripping condensation on the harness connectors. I blew air to remove all wetness and then i disconnected these connectors and used contact cleaning, put it back together, and placed plastic wrapped around the connectors and taped it. It solved the problem. But now i have to solve the problem of where is this condensation coming from. All the hoses have tight clamps but some water accumulates bellow the induction motor that's something that i will work latter on. I was thinking on placing some insulation on the intake and exhaust pipes that go through the attic onto the roof to lower the condensation effect. I hope this helps.

Since it was in spec, what was the actual manifold reading in inches water column.
I get the, "it was within spec" answer from techs, that didn't actually read the pressure.

Hot, neutral and ground are correct?
Has nothing to do with other wiring being done in the house. There are other things that can interfere with the electrical end.
I'm guessing there was.

Since you don't want to answer the questions that can lead to helping you.
You can't be helped.
Iam glad you said it instead of me just what i was thinking
