志高空调2p柜机故障代码故障检修（Zhigao air-conditioner 2p machine fault code troubleshooting） The air conditioning problem is as follows. 1. The fault code of the high frequency fixed frequency machine E1 - compressor high pressure protection E2 - indoor anti-freeze protection E3 - - compressor low pressure protection E4 - high temperature protection for exhaust pipes E5 - - low voltage protection E6 - - electrostatic dust removal 2. High - frequency air-conditioning converter machine E1: the compressor current overheat compressor, high exhaust temperature, module protection, should check whether the overload protector is disconnected and the compressor temperature bag is short circuit. E2: indoor evaporator anti-freeze protection. E3: temperature of the room temperature is short circuit or open. E4: indoor evaporator tube temperature heated head short-circuit or open. E5: internal and external communication failure. A brief introduction of E1 elimination method: first to determine the air conditioning is running for a period of time fail, failure or turned on to discriminate between a system failure or circuit failure, system main consideration: A is not clear, the new machine is easy to be in this situation B overcharge, plus fluorine C external machine is high temperature, ventilated not smooth or form dirty block, environment is bad also possible Iii. Fault code of the machine E1: compressor high pressure protection, when three consecutive seconds detected high pressure protection (more than 27 kg/CM2), closed except light boxes other load, shielding all keys and remote signal, lights flashing and display the E1. E2: indoor anti freeze protection in refrigeration, wet mode, the compressor start 6 minutes, three minutes to detect T steam - 5 ℃ or less, the lights flicker and display the E2, parked outside the compressor, fan: when T steamed 6 ℃ or higher, the compressor has stopped for three minutes, The indicator lamp is out and the liquid crystal recovery is displayed.
