Hi all,

Being springtime I thought it would be good to check my FBH long before it should be needed as I knew it had locked out at some point before last winter.

Just fired up my Thermo Test software and cleared out some faults: low fuel and a crash interlock (from my prang I assume).

I tested each component - all OK or so I though but when trying to fire up the FBH after a while I get an error code "22 - Reference resistance wrong" and it goes through the cooling/shutdown cycle.

I've done a Google but can't find any information on this error.

Anyone got any pointers?

Thanks,
