Where is the Geely ec7 air conditioning relay? Geely ec7 air-conditioning relay is in the indoor relay box assembly, under the steering wheel column, disassemble the steering wheel lower guard plate, you can see many fuses and relays, and the air-conditioning relay can only be seen by disassembling the indoor relay box. The air-conditioning relay is also called the starter relay:
1. The starting relay is a special component for starting the compressor using a single-phase asynchronous motor. The starting relay is a separate component, and its function is to connect and disconnect the attracting coil and the holding coil circuit;
2. In small refrigeration equipment such as refrigerators and air conditioners, the refrigeration compressors mostly use single-phase split-phase asynchronous motors. The function of the starter relay is to help the motor start, and the auxiliary winding will be automatically disconnected after the start is completed to avoid burnouts. Winding coil
3. When the starting relay fails, the compressor will run out of adjustment, the starting capacitor cannot be cut off from the circuit after starting, or the compressor cannot be started after the normally closed contact is disconnected before starting. When the overload protection relay fails, the air conditioner cannot operate normally. The cause is that the relay wire ends are loose or fall off, the contact points are worn or welded, dirty, uneven, and the coil is short-circuited or open.
