The compressor cylinder is what mean? Many dehumidifier salesman rumors so don't understand its meaning, for the first time already. Compressor cylinder is the compressor rotor stuck, compressor can't scroll at the moment.

The reason for the compressor cylinder form card may be frozen oil doesn't come on, not smooth, conflict to add, may be the line in the dust and impurities, form sports side card dead, perhaps simple mechanical fault causing compressor jammed.

The solution:

A percussion method

Generally choose wooden hammer may be selected objects available in situ. When the press launch heavy hammer knock them three solder joints. But should pay attention to the strength, can't knock out of shape. Gently tap the compressor shell, the stuck position slightly loose, sometimes can be a job or 10% higher than the supply voltage to raise, launched frequent impact, this method can solve the cylinder surface smooth, no card, is particularly useful for rotary compressor.

Two strong method

(1) wiring a plug, L directly on C, N M side, the other from the N1, let N1 by tapping the compressor start turning on the power supply side S;

(2) when the compressor start directly with screwdriver conductive side short connect the two ends of the capacitor, moment within 2 s; (hand must hold the insulation end)

If high voltage shock will not solve the problem, clarify the cause of the cylinder is not for lack of oil, which is formed by the mechanical or electrical problems may be, pay attention to safety in operation, watch the electric shock and touch the shell, is the best on the plastic stool or dry wood/paper skin;

Launched three capacitance method Increase the capacitance is one of the most common way, said a brief is on the original capacitance and a capacitance may change a bigger one, to add to launch torque compressor more simple work. Note: the compressor immediately launched two or three seconds to turn it off

Four relief method (also known as the decompression method)

Put the freon off some, to reduce the pressure, and then to use the above method, the comprehensive utilization.

Five pneumatic impact method

The compressor alone to be removed, from the high pressure pipe with nitrogen compressor to a reaction of 0.1 MPA. The holding shaft parts a bit. Air flushing for 5 minutes. Then choose the way.

Method six three-phase power supply

The above doesn't work Three-phase power supply available method, connection is the N of by C.R and S are the front of the different phase. Plug in the short time within 6 seconds.

Seven smooth method, general compressor internal scale, perhaps dirt form, cylinder, the above can play a role, the compressor to be removed, the oil poured out. To heat the oil, and then poured out, one time, is intended to put the dirty things inside the clean out, put the compressor horse 12 hours after washing clean, pour the heat the net, and evaporate. Then to 25 frozen oil, picked up the compressor block a few times on the ground, again to loosen parts. With the above way to launch again

After repair OK for R22, frozen oil, effect will be better.
