Now the high and low temperature test chambers produced by some small manufacturers are really flattering in quality. There are many unreasonable aspects in circuit design and product quality. Although their test chambers are inexpensive, if they fail in the later stages, they may bring expensive maintenance costs to consumers. Today, Xiaobian is going to share with you some common fault diagnosis analysis of high and low temperature test chambers. Interested friends may wish to study together. If you encounter problems, you can repair them yourself. (1) Common faults of the motor 1. The motor winding wiring or lead is disconnected, and the motor lead and the three terminals in the compressor casing fall off, causing the motor to open. To repair this fault, when the power supply voltage is normal, after the high and low temperature test box is turned on, the compressor does not run. The starter winding and the running winding can be measured with a multimeter. The resistance value is infinite, indicating that the motor has a broken circuit. 2. The motor runs through the winding short circuit. At this time, the motor can barely start running, but the sound is obviously larger than the original, the running current is more than 1 time than the normal value, and the resistance of the running winding measured by the multimeter is smaller than the normal value. 3. The motor starts winding short circuit between turns. At this time, the motor can be started normally, but it cannot be started after starting the relay. 4. The motor starting winding and the running winding are short-circuited. At this time, with a multimeter check, the resistance of the starting and running windings is significantly reduced compared to the normal value. The phenomenon is that when the control circuit such as the power supply voltage and the starting relay is normal, the starting relay is continuously overloaded, the thermal protection contact is tripped, and the replacement of one compressor is normal. 5. The common lead of the motor terminal collides with the casing. At this time, the motor can be started and operated, but the ground leakage occurs when the high and low temperature test chambers are well grounded. The following small series will explain the reasons for these failures in the high and low temperature test chambers. Please keep an eye on this site!
