    Hi.

    Heater resistance is usually about 25-30 Ohms. If this is ok then most likely the heater triac on the PCB has failed.

    Also check the heater for insulation too.

    The sensor is possible but not usually something that fails.

    Hi.

    The triac is on the board & if it is the fault then it means a new board.

    Thanks for the help! I think a PCB board might bit a bit pricey and cant be sure this is the problem.

    Thought i would have another look at the PCB ,pulled it out of its case and noticed a dry solder joint. re soldered and tested all ok now,that will teach me to look closer /take the PCB right out next time!Thanks for pointing me in the right direction.
