F H is the fault code for flame detection error, has any cleaned or replaced the flame detection electrode and lead?
Do you know whether it actually lights?

hi Andrew,


 


thanks for your reply. Yes the electrode and lead have been changed. it is not making any sparks.

Andrew Smith, HVAC Technician replied 3 years ago.
Are you able to take the lead off the electrode and hold it a couple of mm away from the case and see if it sparks?

Hello,

It seems the professional has left this conversation. This happens occasionally, and it's usually because the professional thinks that someone else might be a better match for your question. I've been working hard to find a new professional to assist you with your question, but sometimes finding the right professional can take a little longer than expected.

I wonder whether you're OK with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thanks for your patience,

Adam
