I have a Potterton Netaheat 16-22. It completes the cyle igniting the pilot and then the main burner no problem, but then it clicks and cuts out for a split second, then reignites. It continues to click on and off every 3 to 5 seconds. It is also intermittent. Is this a sensor or relay problem? If so which one. Help please.

I recall I once had this problem. It was the cover not sealing properly so the pressure switch went intermittant and caused this to happen.
