The maintenance of household appliances, which many feel are the replacement of spare parts and the checking of circuits, is in fact a number of doors. Old users, masters, or friends who are learning technology are always confronted with “challenges” that are incomprehensible or recurring. This paper, in plain words, categorizes the practical techniques of home electrical maintenance, the idea of trouble-checking and the mine clearance experience commonly used by masters, which i have learned in my many years of practice, as a priority, in the hope that you will be able to keep the road less crooked and “problem” to the end。
Basic methodology for house failure screening
No matter what electrical appliances, the first step to repair is to check. Basic screening is divided into three steps: looking, listening and measuring。
These three moves, which are essentially 90 per cent “presence” and visible short circuits, can be directly located. If these three steps do not reveal anything, the problem will have to be dug deeper, probably on circuit boards, master chips or special failure patterns。

2. Discrepancies in air conditioners
Air conditioning overhauls use refrigerant pressure tables and all-power tables for alternate measurements of pressure and wiring. You can't do more than the computer test。
The problem of “refrigeration” with poor refrigerator repair
Iii. Experience with maintenance of electrical chip-level failure
As long as the master board, whatever the appliances, has a problem, be wary of welding and the ageing of the components。
The pcb plate cut-off line is maintained on a wide range of scraped copper wires, which are found at break points, with a bit of welding over and over with paint packs, and fixes the position with thermal smelting glue to avoid recovery。
Iv. Other common pits and lessons learned in household electrical maintenance v. Summary of common maintenance difficulties vi. Final remarks: maintenance is only afraid of lack of experience
Household electricity maintenance is not technology alone, but experience and care. On the same issue, different people dealt with completely different outcomes, with many old maintenance masters communicating, accumulating cases, and sometimes seemingly complex problems being “one plug in”。
It's an unsolved “ecstasy” problem, so don't go down a single route, move in more directions, and watch out for small components such as lines, vents, sensors。
There's no end to the repair road. These practical lessons are solid. I hope you don't go around the corner and take care of all kinds of electrical problems
