Frequently Asked Questions (FAQs)

1.What does a Con error mean?
A Con message indicates a communication fault between the main PCB and the display board. Therefore, the boiler may need a PCB or display board replacement.

2.What causes PCB issues like F62?
Faulty capacitors on the PCB often trigger the F62 error because they affect gas valve control. However, other components can also cause the same fault.

3.How do I know if my PCB is faulty?
Common signs include a burning smell, a non responsive display, or random boiler shutdowns. In addition, error codes like F61, F62, or Con often point to PCB issues.

4.Can I install a new PCB myself?
No. You should always use a Gas Safe registered engineer because safe fitting and correct setup matter.

5.Do replacement PCB come with warranties?
Yes. Many reputable suppliers offer warranties, and a 12 months warranty is common on new or refurbished boards.
