Is aircon in dry mode?
If it stop, try to use finger or some long object to flick the blower to move..... does it start?

Don’t know.... sounds weird with the blower stopping on its own after 20-30min.

I can’t pin point the problem. If pcb then it might not worth the repair.

Capacitor.

The item to change cost only few bucks.

If fan blower then it is an easy fix.

But I don’t think it is blower problem.

Lel.

Just go inverter r32.

It is not like your fridge or tv or computer ko often right?

Weird fridge.

Anyway... how much it save depends on how you use.
Can be up to 30 percent easily.

Inverter is not only about saving electricity, it is also quieter and more comfortable.

If you really want peace of mind, ask for extended warranty at the shop

The blower motor cost rm 80 usually. The rest is labor.

I still think it is not motor problem.

haha.........

of course can be installed..........but...........
install wrongly or badly.........it will be endless repairs and troubleshooting

and i don't think panasonic will honor the warranty

outdoor unit has no sensor.

if you know what you are doing, i suggest change the indoor room sensor and indoor coil sensor.

the two sensor together should cost less than rm 30. likely room sensor is the one giving wrong information to the motherboard. but since you are opening it might as well change the coil sensor together.......

All portable aircon are crap.

Sure you can get cold air blowing at you but the electric bill will be big.

indoor coil leak is quite common.........especially at all the C joints at both sides of the evaporator coil.

Lol.
Many problem.
1. Your indoor coil could be very dirty and blocked. There is still liquid state gas that is being sucked into the compressor. If the suction line got frost on it then can confirm the indoor unit coil is blocked with dust.
2. The filter for the refrigerant might be blocked and faulty.

I suggest have a aircon guy clean the indoor and outdoor unit.
Maybe it is the blocked indoor unit that is causing the airflow to be bad. Hey if you hear sounds like fu fu fu when the cross fan is spinning then confirm block la.

Lol. Another crappy aircon guy.

Do whatever you want la. It is an old aircon anyway.

Erm. Capacitor size depends on the blower motor. 1hp= 1uf might not be the case.

Daikin is from oyl factory Malaysia. Expect part prices to be cheaper by rm 20-30

Panasonic has history of problem with sensor also.
Old York produced from oyl factory has lousy capacitor that fail quickly.....

Meh.

Each brand got their own problem.

Depends on location.
Those inside wall don’t matter.
Those outdoor don’t matter much.
Those running horizontally across ceiling could be potential problem as condensation build up and drip, damaging the ceiling.

2 possible reasons.......

1. defect of flexible cable connecting the switch to aircon. poor quality ones can break internally the connection of the wires.

2. blown fuse on the aircon pcb........usually only happen during operation then stop suddenly........requires further investigation if this is the case.

but, if you dont have electrical knowledge, better get a professional

have they tested the current in amps drawn by the compressor?

here's the basics :

1. 1hp aircon inverter type i assume current drawn during cooling phase is 3+ to 4 amps. usually around 3.5amp when running close to 100% power. check your own unit for more accurate figures.
2. also have to check gas pressure together with amount of amp drawn. i assume refrigerant is r410a for an aircon of that age. gas pressure at the suction line would be more than 100 psi and less than 140 psi during cooling phase.

scenario :

1. if amp drawn is low and refrigerant pressure is low......means you are low on refrigerant and having a refrigerant leak
2. if amp drawn is very low and refrigerant pressure is very high........,means that the compressor is not running
3. if amp drawn is high and refrigerant pressure is high, it could mean that the outdoor coil is dirty and possible outdoor fan malfunction
4. if amp drawn is normal and refrigerant pressure is low............it could mean indoor coil is dirty or indoor fan malfunction
5. if amp drawn is low and refrigerant pressure is normal/a bit higher than normal, it could mean compressor speed is slower than usual which could be caused by :1. compressor run capacitor dying, 2. signal sent by indoor to outdoor does not represent the actual condition......check indoor coil sensor/indoor room sensor.

for an aircon of 6 years.......i would check the health of the capacitor and sensor. that's my suspicion.

One simple way to test is to clamp the wire to outdoor unit. Either the neutral or live can do.

Read the current draw.
If draws at least 0.2-0.3 , you know the outdoor fan is working. And hence outdoor fan cap is good.

In the case of bad compressor cap, it will fluctuate between that above number and some random big number for a fraction of a second, like 0.3 then suddenly 20 then back either to 0( indoor circuit board trip and will show error code) or back to 0.3( this will cycle a few times and aircon will not be cold). Reasoning for the big number like 20 amp is due to compressor not running and hence high load during static condition.

If after change cap(assuming cap is good and correctly wired) still the same , the compressor is dead

Just sharing some safe ways of testing without going to outdoor and to decide on next step based on the diagnosis.
