Open door alarm

(None)

Compressor on and off Control specifications

1. When one of the following conditions is met, the compressor stops:
   1. Tr ≤ Trt;
2. When all the following conditions are met, the compressor starts up:
   1. Tr ≥Trk;

★ When 1. and 2. are not satisfied, the compressor maintains the original state

Troubleshooting Method

Not cooling

PTC: 16~50 Ω
Rmc: 10~20 Ω
Rsc: 30~50 Ω
Rms=Rmc+Rsc

Common phenomenon of no cooling:

• The connector has a leak or the terminals are loose.
• Defective protector or starter.
• The connector is reversed, the timer is connected to the wrong line, or the timer is not reset.
• The leakage of the refrigeration system, welding plugs, the capillary depth of the dryer is not enough lead to solder plug.

No working of compressor

Thermostat malfunction/Undercooling
