As shown in the figure blew, the compressor doesn't quit and fails. It is a problem with the temperature management circuit. The thermostat must be replaced................................................................................ freezer freezes solely the left ingredient has ice or the alternative component freezes, freezesUneven analysis, as proven within the determine blew, ends in the failure of the compressor now not shutting down is not the situation of the thermostatIt is a wide range of problems equivalent to internal leakage and working pressure, piping and compressor problems.......................................................................................... your fridge thermostat is two feet, you also can purchase our three feet thermostat, which are used instead, as lengthy since the length of the line is enoughH is hooked up to the brown wire, which is the dwell twine of the ability supply;L is attached to the gray wire, which is the live wire of the lamp;C is hooked up to the white wire, which is the stay wire of the compressor to the ability delivery terminal, C---connected to the compressor control terminal, L---connected to the temperature reimbursement management terminal two-leg temperature leadership only needs to be connected to the two ft of the three-leg temperature-controlled HC standard:1. Check whether or not the original mechanical device is WDF variety or WPF type (the two types are usually not common).
