Got called out to look at a boiler that is cutting out intermittently, the boiler always comes on in the morning and is usually set for 18 c in daytime. The problem usually occurs when the customer is calling for more heat at nighttime as they turn it up to 21 c but then the boiler cuts out and does not come back in for hours. Initially I was thinking faulty stat or something along those lines, but when I inspected the boiler I noticed two things.
1. The fans propellers are missing
2. When the boiler is cut of it won't try to go through the inanition process even after reset, but when you tap the control box that houses the gas valve it kicks in, fan runs and hey presto the boiler fires up.
The fan appears to be working OK apart from the missing blades and it has continuity through it, but am torn between a fault on the gas valve or fan fault as maybe the lack of propeller blades is causing it not to run adequately.
Since leaving the job the boiler worked fine for 3 days then started to cut out again but again worked when the control box was tapped.
What does everyone else think.
Thanks
