Cobra/Carrier Furnace Cir: 1995 or 96


Unit may cycle properly during the day with warmer temp's.
When temp drops (evening or morning) unit fails to ignite.
Blower blow's, second stage blower functions, ignitor heats (new) but gas fails to flow (I think).
Placed a small space heater near gas valve to warm the valve (cycled perfectly),
I am replacing the gas valve in the morning.
Question:
Is the gas valve solenoid temp sensative?
(I hear solenoid click but fails to ignite unless valve warm)
Is gas valve (White Rodgers 36E EF32CW183A) the real problem?
Gas Valve functions @ warm temperture. Why not at low temp?

I live in Las Vegas with moderate dry weather.
