Hisense inverter automatically shut down the press hang central air conditioning, fans turn Published: January 13, 2015 Source: Unknown Hits: 141 Symptom: press automatically shut down, turn the fan Analysis: First, look at the code in case of failure of this lamp LED1 , LED2, LED3 display state as a bright flash, off the overcurrent protection, troubleshooting, mainly divided into the following steps: (1) emphasis on the DC20V gear multimeter, measure the resistance R14 for voltage of about 1.5V (this voltage varies with the current changes) If you have around 1.5V voltage, there is an issue chip, if there is no voltage of 1.5V, indicating LM358N stage before there is a problem, when the measured voltage is 5V, indicating breakdown diode D5 (2) Measurement resistor R11 is about 0.09V voltage (the voltage change with the current changes) Xuzhou central air conditioning installation telephone, if there is a voltage of about 0.09V, indicating LM358N bad, if not 0.09V voltage instructions before sampling resistance level problems ( 3) with a multimeter ohm power measurement sampling resistor R5, R1, R56 is open, the measured R1, R5 normal resistance, R56 R56 resistor open replace troubleshooting. Environmentally friendly air-conditioning maintenance cleaning 1. Clean the filter method for removing the evaporator filter, with high pressure water rinse, as usual that is able to wash and clean. If the filter material online is difficult to wash, to use high-pressure water wash evaporation tank filter and air conditioners, air conditioning and then further filter online spray washing liquid, washing liquid is completely soaked until five minutes after the filter central air-conditioning maintenance, Xuzhou, and then high pressure rinse water until the filtered impurities to leave to the Internet. 22. After removing the taint environmental conditioning air conditioner run for a long time, if not on the air conditioner tune usually held good washing nursed back to health, probably caused by air conditioners cool breeze sent smell, then just press a step to clean the filter and environmental protection Air conditioning can sink. If the odor is still available in the boot of the environment, to the sink to add some chlorine disinfectant, disinfectant allow substantial penetration through every corner of the screen and cold machine, repeat the disinfection of air-conditioners frequently can smell the behavior. 33. winter environmental air conditioning maintenance way into winter, if your air conditioner is no longer used by winter, this time to be held on the air-conditioner maintenance nursed simple thing. First closed central air conditioner water valve reconstruction Xuzhou, remove the filter, in accordance clean "evaporation filter," while water tank drain water, thoroughly clean the sink air conditioner (careful, do not let the water flow to the motor above). Conditional can hold a comprehensive disinfection. After the washing is complete, replace the filter. At this machine blowing 5-8 minutes, until the filter dry, closed air conditioner total power supply.
