First we observe that the fault is detected on the computer if a power failure mail or refrigerator.
observed in the case of an acoustic signal, light or any entry in the display we see the manufacturer's installation manual.
If this machine does not have this type of failure can have a malfunction:
Due to lack of load or overload: this will be indicated by the bridge gauge or analyzer, if the pressure is low in the circuit below normal (see table coolant pressure), chances are we've got a leak, excess fluid in the circuit can detect a current clamp comparing actual consumption with the theoretical data plate of the outdoor unit, a machine with enough excess fluid consumed over what makes the film.
cooling line is frozen: we see that we have no lack of charge or release (you can also note the lack of load checking liquid line is hot or cold and cold gas is or temp. environment.
The machine is in depression: usually happens to us when we have a blockage in the circuit so the gap is made to the circuit through the compressor.
For escape: if the machine has been working to verify whether a patch of oil, which does not indicate the approximate point where this, or use electronic devices for the detection of different refrigerants, but the best method is a soap and water as you have pressure within the circuit.
Electrical part: see immediately if we tension in the indoor unit if we do not start this, o comprobar si hay tensión en la unidad exterior si no nos arranca.
Otra prueba es comprobar las bobinas del compresor con un tester para comprobar el estado de este, y realizar una comprobación al cableado de la máquina.
Parte electrónica: si lo que no arranca es la unidad interior comprobar fusible de placa y transformador si se dispones de este, revisar el cableado y comprobar que todo esta correcto.
Si se ha comprobado lo anterior y la máquina no presenta una señal de alarma, automáticamente cambiar placa.
En el caso de que aparezca una señal de alarma esta puede ser por: fallo en el interconexionado de la placa, sonda de inmersión de la unidad interior o exterior, sonda environment outside or inside the unit, failed fans, etc ...
Especially when you perform a repair to remain calm and think positively because there is no irreparable machine.
I found on several occasions that the installers do not make minimum facilities for example if the split is separated by a wall of the condenser tube perform a cold installation of less than 40 cm, then we can find eye problems including noise problems refrigerator so it is advisable to make a return to copper tube in a place that is not very visible for example behind the condensing unit. I have also found
installers who will do minimum tool-repair as an analyzer (gauge bridge), a thermometer or a clamp (These three tools are essential in the case of maintenance personnel of any company, as indicated in a previous article we found problems with the analyzer refrigerators, with the clip too, and also electrical problems with the thermometer ensures the proper performance of the air conditioning.
So before you call any service center depending on the problem we see at high pressures and low differential temperature and use of both cold and heat, as with all these data, the call center We can provide a solution to the problem. Now in winter
commonly encountered problems is lack of frozen cargo in the outdoor unit, which probes immersion field units tell them if you have freezing weather, this is solved by adding charge provided that perform this operation according to manufacturer additional charge g / m.
If defrost problem of excessive and persistent freezing kits can be used to defrost or just a very simple kits ESISTO silicon with a resistance, a thermostat and a probe, this resistance is rolled to the bottom of the battery condensing unit and the thermostat probe the environment for example in the contrary to the fan and the thermostat set at 5 º C eg positive when the temperature drops acts of resistance by avoiding the creation of Frost (these kits have a low power consumption).
Another problem is investment valves (four-way valve), or your coil for four-way valve usually with a few taps is usually solved and remaining stuck in last place or if that fails have change, or the problem we can be found in the spool valve has been bypassed so the check and change it.
To determine these two problems or we do it with the forceps or with the analyzer.
Another problem is the freezing of the coolant bottle to carry the burden of a team that freezing slows us over the refrigerant charge therefore recommend the use of a kit that is placed around the bottle of low weight that slows freezing bottle and allows us to load in less time, this kit TOOLS ITE factory.
But above all it must fix the installer as is the eyes of technical call center.
