I am having a problem with my Potterton II cf 60 boiler.
The pilot is lit but the main burner does not light. Controls calling for heat. (points to gas valve)
There is 240v going to the solenoid on top of the valve.
A new gas valve cost £50 plus vat but how can I be sure that its not the coil on the solenoid that's burnt out. A new coil doesn't come with the valve. I would hate to pay for a new gas valve and find out its something else. Is there any way of being sure?
Thanks
Joe
