On the air conditioners and split systems Gree, not so many sensors of the protection system, everything is simplified and unified.
Self-diagnosis of air conditioners Gree
What is the explanation for the philistine?
The explanation is simple. On conditioners and split systems Gree, not so many sensors of the protection system. Those. Everything is simplified.
The internal self-diagnosis of Gree conditioners is unified and almost identical in error positions of inexpensive air conditioners, for example such as Pioneer, General Climate, Lessar and others.
You will laugh, but for example, the catalog of air conditioners Supra, did not even change the name of the outdoor unit, maybe you do not have enough skills in photoshop, maybe you did not find it necessary.
In a word, how are the Supra air conditioners certified in Russia? For me, a mystery. Catalog of Supra !! In fact. Heh ...
Self-diagnosis of air conditioners Gree is, -
High pressure protection,
Protection against freezing of the evaporator,
Compressor overload protection,
Errors in switching air conditioner during installation, confusing wires,
And the errors of the temperature sensors of the evaporator and condenser.
Everything, do not agree much. Gree, as an air conditioner, is simple functionally, so there are not so many error codes.
There are disadvantages of this simplification, these are weak varistors of the control board, insufficient smoothing
Gree, as an air conditioner, is simple functionally, so there are not so many error codes.
Error codes table, continued.
Currents during voltage surges. Trifle, but it must be borne in mind when repairing air conditioners Gree and their counterparts.
Example: country cottage. The owners leaving the dacha usually de-energize the building with a common switch.
Those. They put out everything and calmed down. We arrived ... Turned on the light of the same knife, and air conditioning, refrigerator, or other household appliances does not work. Why? The answer is simple.
When the power is turned on with the load, current and voltage surges occur.
Varistors, smoothing voltage surges do not cope with the current load and burn out, burn well with smoke and soot, in the absence of a protective shell, usually together with the fuse of the control board of the indoor unit of the split system.
There are "specialists" who use the wire when fusing the fuse. Can I do this? It is possible, but then, apart from the varistors, the control board, the fan of the indoor unit, will also burn out, and ... it raced right up to the windings of the compressor of the outdoor unit of the air conditioner.
Fireworks at the cottage. - Expensive repair.
Troubleshooting and breakdowns of the air conditioner, we as usual start with:
- failure of the refrigeration circuit,
- malfunction of the electrical part, the electrical system. Power and air conditioning control.
