Question

Please can you help. I have a Thertford N100 LCD fridge and it keeps poping up with fault code 9 even if its been running for a couple of hours. Could this be a fault with a thermocoupling or something completely diffrent

Answer

Fault 9 indicates that the gas flame has failed to ignite. If you are happy that the flame is OK then it does point to a fault with the flame recognition system and as you suggest it could be caused by the thermocouple, or maybe the gas valve, having an intermittent fault. Difficult to diagnose from a distance.
