How to adjust the overheat thermal protector of your refrigerator?
When your refrigerator has a too large running current or fails in a normal start, the excessive current in the circuit will result in increased heat from the resistance wire and the heat will cause the butteryfly bimetal disc on the resistance wire to bend after being heated to a certain extent. At this time the overheat thermal protector takes action to immediately open the contactor and cut off the current, thus taking the effect of overload protection (in case of overheated compressor shell, the protection takes place the same way). After the contactor breaks the circuit, the bimetal disc gradually cools down to a certain extent and closes to make the circuit. The break and make process normally takes 60 seconds.
When the protector is being repaired or adjusted, the thermal protector should be connected in series in the measuring circuit to lift the current. When the ampere meter indicates 6A, the overload protector contactor snaps open and no current is indicated. Record the time. Observe the reset time and record the overload delay again. After one to three trips take the mean value to check against the standard parameters. In case of inconformity, you can regulate the adjusting screw to adjust. The shell cover should be closed otherwise the reset temperature will be shortened.
