What if you can't find a solution to some of the air conditioning problems that clients face? So you can try to contact a passenger suit. What's going on with hale ac? Let's have a little help with the hal ac repairs。
How do you fix the usual hair ac problems
1. Hale ac ac power supply
Method of repair: on-board burning and plumbing。
Pipes: it is clear that circuits have short circuits and that the short circuits will be judged using a universal meter to detect the barrier. Together, they can also be examined by dividing, for example, by disconnecting the transformer's primary circuit, through a tester, which, if not ready, states that the burning is due to short circuits such as pressure-sensitive electrical resistance or the presence of a porcelain electric face, and short circuits such as transformers or whole-stream tubes
Pipes: whether sub- and primary transformers reach 220 volts and 10-13 volt volts can be used to communicate in a single form, and, if so, whether +9-12 volts and +5 volts can be effectively distinguished by using an additional direct flow schedule of 7812 and 7805。
2. Hale ac relay circuits
Method of overhaul: distinguishing between relay damage or set success rate driver modules loss
When it's on, the beeper sounds, the whole machine is inoperable, and most of the success rate drive module is damaged
When it's turned on, some of the work is abnormal, most of the relays are damaged, and the relays are adhesive, so it's still burned
(b) there was no adsorption, stating that relay wires were burned;
It will also be able to judge good and bad with a universal om watch, shut down the power supply and measure the electrical resistance of the wire. The normal normal electrical resistance value is several hundred om, if infinity or zero, indicating damage to relays;
Measure points, if the resistance value is zero, make the contact sticky。
Air conditioning temperature circuits
(a) method of overhaul: thermally sensitive electrical resistance is an electrical resistance with a negative temperature coefficient, with lower temperatures and greater resistance;
The barrier is about 5-20k at 25 degrees. An om scale with a small or infinity resistance value can be used, stating that heat-sensitive electrical resistance damage is to be replaced。
4. Air-conditioning repositioning circuits
Method of overhaul: the compound voltage is a delayed increase in voltage, which can be investigated using the direct flow of the meter。
If the investigation is not clear, the oscilloscope will be tested. At the time of testing, a baseline was seen to float and then become high-altitude, above which was the start-up process of the compound voltage. If the baseline is non-floating, clarify that there is a problem with secondary circuits。
5. Air-conditioning reception circuits
The normal value shall be the electrical pole +5 volt voltage and the signal voltage +2. 5 volts. Common problems include electric convulsions or head damage。
