What it is
The Fuse 3.15AT is a 3.15 amp fuse supplied under manufacturer part number 160036 by Main. It is used on Main and Potterton gas boiler ranges, where it protects the appliance's electrical circuit. A failed fuse will interrupt the power supply to the boiler controls.
Signs this part needs replacing
- Boiler is completely dead with no power or display
- No response to a call for heat or hot water
- Fuse fails a continuity test on a multimeter
- Fuse body shows discolouration, blackening or a broken element
- Boiler repeatedly blows the fuse after replacement
Before you order
- Confirm the existing fuse is rated 3.15 A and matches the type designation
- Check your appliance model against the fitment list above
- Isolate the electrical supply before removing or fitting the fuse
- If a replacement fuse blows again, investigate the underlying electrical fault rather than replacing it repeatedly
