Ideal Classic FF No Heating Or Hot Water

Was asked to look at an Ideal Classic which was not working for either heating or hot water. Looking at the boiler I could see an orange glow coming from inside the control box and so I knew it was receiving demand. Feeling the case I could feel some warmth even thought the boiler had not been working. I removed the case and could smell that the fan was overheating from trying to turn.

I replaced the fan with the correct version and the boiler was working fine again.

There are two different fans for different versions of the boiler which look similar. The obvious difference between the fans being the terminal positions. On one version the terminals are both on the left hand side of the fan motor and the wiring loom is shorter for these terminals. On the other version, the terminals are on opposing sides of the fan motor as you look at the fan motor from the front and the grey wires are longer in this case. There are other fans for other versions of the Ideal Classic as well such as the NF30-80.

It is also important to remember to slide the flue back together correctly. If the inner flue is not connected back up the boiler will baffle out when it lights and the boiler will cycle on and off.
