    Default Help with a HR92

    Hi, after some help.

    One of my HR92s has gone wrong. On the screen it's showing frost and d4.8 and on the main Evo control panel the temp fluctuates from a minus number to 99c! I have tried unbinding it and removing batteries but no luck.

    Anything else I can try?

    Sounds like the temperature sensor in it is faulty. As it's soldered to the main PCB I'd say it's not economically repairable.

    It's always worth checking that it's not caused by a dry joint if you are able.
