Damage: AC can not cool
Symptoms appear:Condenser fan motor is not spinning, spinning the compressor motor.
The initial examination:
Turn on the AC (through the evaporator.)
Observe the symptoms that appear include air out of the evaporator blower is cold or not?
The result was: rotary evaporator blower motor, but air can not cold.
Observe the condenser!
The result was: - Water is dripping from the drain hose.- The compressor spins, the condenser fan is not spinning.Examination of the AC working.
Open the lid valve in the condenser (3 way valve)
Attach a double valve manifold meters. Observe the result: the pressure was very low (0 psi), which means the gas is discharged from a pipeline leak.
Turn off the AC again.
Means the need to repair two sections:
Evaporator section: clean front grille and filter2nya.
Condenser section: - Improved condenser fan motor
- Cleaning of dirt on the condenser.Due to motor repairs need to reduce / remove the outdoor unit (condenser) from the holder it is necessary step to save gas while R 22 into the compressor.The process of storing the gas the same as steps to disable the AC.
Motor repair it is necessary to step back charging R22 gas into the air conditioning system.
After AC power off
Disconnect the power cord, check the terminals on the cable colors so as not to forget when put back.
Disconnect the pipe from the evaporator to remove the nut-nut fastener.
For a while, close the ends of the condenser tube and the pipe connecting the open with plastic so as not to let dirt.
Lepaslah condenser amplifier of bolt nut holder.
Do repairs and checking the condenser fan motor.
Examination of motor• In a state with no voltage, fan blades can be rotated smoothly by hand.• When connected to a voltage source hard fan in turn by hand can not even., There seems to be the brakes.· Tested try the capacitor is replaced with a new capacitor, the motor remains difficult to spin.· Taken conclusion was faulty motor (the motor shaft is not funny = center).
After the motor repaired;· Place the re-condenser unit on the stand before.· Reconnecting the pipes as the original state.
The process of cooling the gas filling return
Is the same as step activates AC. Namely:
1. Connect the manifold gauge hose (double meter) on the teat drain plug on the outdoor unit (condenser) which is the left channel is facing down. Tap and double tap valves are still closed state.2. Connect the power cord plug at the evaporator to the source voltage (meshes). After all the connections and the installation is complete then ready to step activate AC.3. By using the L key (key peg) is appropriate, play a little at the drain plug tap counter-clockwise to open the faucet tap channel compressor contained in the condenser (picture right). Amati was the appointment of a meter double, double meter needle will move to the right / the numbers go up and stops at a certain rate (eg 200 psi). Let this state for a while so that refrigerant gas circulated to all channels.4. Using foam soap olesilah water pipe connections to determine whether there is a connection that is leaking.· In the event there is a leak in one pipe connection close the drain plug press compressor .. Fix the connection before the pipe by tightening the nut or replace the seal-seal the damaged tape to reassemble until absolutely nothing is leaking a bit.· Repeat steps to open a channel and check sambungab with foam soap earlier.5. If there are no gas leaks at the connections, do the "penggebresan" to remove the residual air remaining in the manifold hose blue. The trick is, open the faucet a snap manifold dual meters until the end of the yellow hose manifold that opens the gas issue reads "jeesss". Repeat this step 3 times gusts of gas with a short lag time, eg jeess jeess .... ... jeess. Close the valve tightly double.6. After that, with the key L is also open the cover bolts to the compressor suction line inputs are on the press line. After closing the channel was opened refrigerant gas (Freon) will circulate / circulation of the compressor - condenser and returned to the compressor again. Wait a few moments.
7. Turn on AC power by pressing the ON button on the indoor unit (evaporator) or use an existing remote control. (For now usually remote) is marked with a resounding "tiit". AC compressor can not directly work / life, wait a while (± 3menit) to know the workings of the compressor.8. After approximately 3 minutes, the compressor will start work / bike path and circulate the refrigerant gas R 22 that already exist throughout the air conditioning system resulting in continuous circulation.9. To know the usage time of a normal AC current by what does not use pliers amperes / pliers to measure the current flow into the compressor and condenser fan motor on the part. Clip pliers amperage on one power cable that goes into the condenser, observe and read. If the current user is not normal (more than the price of its name plate, eg 3 Ampere), do the repairs first before proceeding to enable the AC.10. Wait a few moments and look for work check hasl AC. To ensure that the AC is working normally iindikasi The most obvious is through the evaporator (indoor unit) actually produce cold air / cold and is characterized also by the presence of water dripping from the drain hose water on the outdoor unit / condenser.11. If there is water dripping from the drain hose means a normal working process and the activation of AC has been successfully conditioned.12. Remove the return hose from the valve manifold drain plug and cover again with myrrh TSB channels cover the pipe end as the original state.13. AC activation is complete.14. Offkan re-conditioned when the trial period has been completed by pressing the remote there.
