What does the Ideal Logic Max F41 fault code mean?
The F41 fault code on the Ideal Logic Max indicates a central heating (CH) temperature fault, which typically means that the boiler is unable to detect the correct temperature of the water circulating through the heating system. This can lead to inefficient heating and potential system failures if not addressed.
Common Causes
- Faulty Temperature Sensor: The temperature sensor may be malfunctioning, causing incorrect readings and triggering the fault code.
- Blocked or Dirty Heat Exchanger: A blockage in the heat exchanger can prevent proper heat transfer, leading to temperature discrepancies.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and fix this issue, as it may involve gas or electrical components that require professional handling.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F41 fault could be around £150 to £250, primarily depending on whether the temperature sensor needs replacing or if the heat exchanger requires cleaning or servicing.
