I have a Trane XR80 gas furnace that started to act up recently. I
narrowed down to the gas valve. It was getting 24V, but not opening. I
lightly tapped it with a hammer, and it started working again.

Are these valves similiar to gas dryer valves? I had a problem with my
dryer one time, and just replaced the solenoids, and was fixed. Can I
do the same with a furnace gas valve? This is the gas valve on my
furnace now:

There is a plastic cover on it which can be removed. If I remove it,
will I find the solenoids?


I have repaired bad solder joints on the little circuit boards on gas
valves but the solenoids I've seen in the defective valves could
possibly be replaced if new ones were available but because of liability
concerns, I doubt that any repair company would want to do it. You may
find a simple bad connection but if there is scoring or any mechanical
damage to the valve, you'd be much safer replacing the valve.
