We have a venerable Potterton Netaheat 80e which we only turn on occasionally when it gets particularly cold, it does have a clock controller but it runs on expensive LPG and we have a wood burner that keeps much of the house warm.
I have just turned it on for the first time this year and it isn't lighting. The pilot flame lights OK and the boiler makes all the right sort of noises but the main flame doesn't light.
The troubleshooting guide suggests that the solenoid valve GV2 is faulty, does sort of make sense if it's stuck shut. Is this a common/likely fault and am I likely to be able to unstick it or should I simple replace it?
