Had the same fault error code f1 after a few minutes and then shut down. Here tis for all! Remove bottom plastic fan vent and then remove the thermal switch located in the middle of the fan outlet. Two wires connect either end. Solder together the two wires and insulate they are live! The fire will work correctly from then. Dont forget to disconnect the power before you repair the fault. Ps throw the thermal switch away! Cheers Kevin B Adelaide.
+ OK when fixed!
