I had a look at a
Ravenheat CSI Primary boiler today which was not working properly. When the boiler was coming on for the heating and hot water sometimes it would work fine other times it would come on and off frequently. The fan would start up and burner light, running at full power for 30 seconds or so before the fan and burner would cut out. Then the process would start over again, occasionally going to low flame after the initial high flame. Sometimes the fan would only run for a few seconds before cutting out.
This is quite a common issue on these boilers and not the first time the fan control PCB has been replaced. I replaced the
fan control PCB which has solved the problem.
