Anyone know what causes the Logic range to go to F9 fault, MI's just say PCB fault-replace PCB.
Serviced a 24+ Heat today, 1 year old. Carried out the service, fired it up and ran through FGA checks etc. Tidied up and was talking to the customer and noticed the F9 showing. Wouldn't reset, turned off the spur and then back on, fired up fine ran through sequence, pump/fan over run then back to normal. Just seemed to play up once for some reason. Boiler has a condo pump, which the float switch had cut the power to the boiler after servicing, but it fired up once the pump was emptied.
MI's don't give much away..... Just your PCB's gubbed! New one!
