What does the Glow-worm Energy F92 fault code mean?
The F92 fault code indicates a central heating flame fault, which means the boiler is unable to detect a flame during operation. This can lead to the boiler shutting down to prevent unsafe conditions.
Common Causes
- Flame Sensor Issue: A faulty or dirty flame sensor may not detect the flame, causing the boiler to shut down.
- Gas Supply Problem: Insufficient gas supply or a blockage in the gas line can prevent the burner from igniting properly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that can be dangerous to handle without proper training.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F92 fault could be around £150 to £250, primarily depending on whether the flame sensor needs cleaning or replacement, or if there are gas supply issues that require more extensive work.
