Tempstar DC90 Problem with gas Valve

My furnace sometimes (1 out of every 4-5 times) won't kick on.

The problem appears to be where the plug from the flame sensor connects to the gas valve. ALl I have to do to get the furance to kick on is lightly press on the plug. The plug itself seem to be good. It feels like they might be a cracked lead on the circuit board that the plug is plugged into.

It is possible to remove the valve actuator off of the top of the valve. Or does the valve need to be replaced?

Thanks

Replacing the gas valve isn't a DIY job in my opinion. There are several adjustments that need to be made to match the gas valve to the furnace, and the typical DIY can't be expected to set up the gas valve correctly, in my experience.

So if you are satisfied you have identified the problem, I'd shop for a repair service to replace the valve.

I am on the same page as you. I was hoping I might be able to pull the actuator and control board off of the valve without having to remove the valve completely.

But it doesn't look like that is possible. Based on the troubleshooting I have done so far, I would have a hard time thinking the the problem would be else where.

Thanks for the comments. Now to find someone to do the repair.
