电冰箱的启动异常,除与低电压和压缩机以继电器有关外,还常与温控器故障有关,而这种故障一般不易引起注意。温控器使用较长时间后,其触点表面氧化和烧蚀及温控器质量不佳,可导致触点闭合迟缓无力,使电冰箱启动时间变长,甚至不能启动。判断温控器是否出现故障,可采用以下检查方法:卸下电冰箱启动与保护继电器,代之以一个人工控制的启动运转电路(根据电冰箱启动运转原理自制的配电板),人工控制电冰箱压缩机的起动运转。若起动运转正常,且电流在额定值内,则说明压缩机工作 The abnormal start-up of the refrigerator is not only related to the low voltage and the relay is related to the relay, but also often related to the failure of the thermostat, and such failure is generally not easy to attract attention. When the thermostat is used for a long time, the oxidation and ablation of its contact surface and the poor quality of the thermostat may cause the contact closure to be slow and inefficient, which may cause the refrigerator to start longer and may not even start. To determine whether the thermostat has failed, the following inspection methods can be used: Remove the refrigerator start and protection relay, and replace it with a manually controlled start-up circuit (a self-made switchboard based on the refrigerator start-up operation principle), and manually control the electricity. The refrigerator compressor starts running. If the starting operation is normal and the current is within the rated value, then the compressor is working
