Abstract：An American Buehler Simpli Met 1000 Automatic Mounting Press machine does notworkproperly. Fault 1： After pressurization，the working state always stops at the "preheating" stage，and does not heat.After unloading，the sample is cold.The checkresult shows that thebimetal temperatureprotectionswitch of the heating part jumps off and becomesnormalaftermanual reset. Fault2：After in laying，the temperature of the sample is relatively high and there is no cooling effect. The inspection result shows that there is no cooling water outflow during the final "cooling" stage. The reason is that the impurities in the copper water filter block on the internal filter screen，and it returns to normal after cleaning. Fault3：It can be heated in the"preheating"stage but can not enter the next "heating" stage.The inspection results show that the cooling water solenoid valve is not closed tightly，a small amount of continuous out flow of water takes away the heat，affecting the"preheating"stage temperature increase. After cleaning，it returns to normal.
