"defective gas valve. However, check there is power from the PCB to the gas valve. If not, it's not the gas valve at all, but either the PCB or the wiring harness"
We have had the house for 7 years and it hasnt been serviced in that time. Is it possible to clean the heat exchanger by my self. I have pretty good access to remove it but not sure the steps I need to take before doing so?
