What it is
The Ravenheat 0012FUS05020/0 is a 4 amp internal fuse for the ignition box circuit in Ravenheat gas boilers. It is a service part for the CSI and RSF appliance families. The fuse provides circuit protection within the ignition box circuit.
Signs this part needs replacing
- Boiler fails to ignite or produce a spark at the ignition box.
- No power reaches the ignition box after the fuse has blown.
- The fuse shows a broken element or tests open circuit with a multimeter.
- Repeated fuse failure after replacement, indicating a fault elsewhere in the ignition circuit.
- Boiler locks out or shuts down without completing the normal ignition sequence.
Before you order
- Confirm the existing fuse is rated at 4 amp and matches the mounting arrangement in the ignition box.
- Check the appliance model and GC number against the compatibility list.
- Investigate the cause of any blown fuse before fitting a replacement, as a fault elsewhere can cause repeat failure.
- Isolate the boiler from the electrical supply before checking or replacing the fuse.
