    H4-01

    On sharp 287 I got a H4-01, I believe that it might be the thermoswitch, any other suggestions?

    Most likley the themoswitch I dont remember if its a thermofuse but if its a thermoswitch theres two fixes replace or reset it you can reset it after two hours in the freezer. If your in pinch through it to the floor from six feet and that will reset the thin conductor sphere. Even though it may work you still have to replace it because it has not the same tolerance as when not triggered.
    Make sure you clean the thermistor Orange foil wired thing this is the cause of most over heat shutdowns last check cooling fans and space from the wall for proper ventilacion.
    Copier should warmup in the specified time according .
    You will also have to do Crop 14 start.
