Re: Desperate. Help Please
Did the technician give you any sort of report on what they checked and found to be wrong with the unit?
Re: Desperate. Help Please
No report Sean. We’ve had a litany of issues in the past. Years ago the cooling stopped. Numerous technicians tried to fix it but were unsuccessful. This same technician persisted and solved it by replacing some type of thermostat and it worked extremely well till this issue surfaced. He’s been very good. But after this latest issue surfaced last year, even he is scratching his head. The unit has been regassed too.
Re: Desperate. Help Please
Have you had a technician that actually works for Daikin have a look at it?
With a high pressure fault I would be starting with checking the indoor unit filter and heat exchanger are clean, and that there is good air flow into and out of the ducts. After that you kind of need a technician to do checks, and with the unit faulting every half hour at least the fault is happening often enough for them to see whats happening.
Maybe others on the forum will have more suggestions for you.
Re: Desperate. Help Please
A very long story but I’ll try to make it as short as possible. When we built the house the builders engaged a Daikin dealer from a neighbouring town. The builder did not use the local Daikin dealer. Shortly after moving in the unit kept going into defrost. It was not heating the house adequately. The builders daikin dealer could not ascertain the fault. He said that’s just the way these units are. He was useless, he couldn’t even operate the control panel properly. We then contacted the local Daikin dealer. He came and assessed the unit. He said the unit was not correctly installed citing numerous problems. Even though the unit was still under warranty at the time, Daikin refused to rectify the fault. They and the other local Daikin dealer told us we had to pay for our own repairs first and then sue the other dealer for the costs. We were not happy about that because It was too risky. The unit worked on and off but far below standard. We then contacted another Daikin dealer from a neighbouring town who rectified some of the problems. They said we had too much ducting work and they also changed the control panel. The unit improved a tad but again defrosting was still occurring far too often. One summer the cooling broke down. We called the local Daikin dealer but he was very upset with us because we hadn’t gone ahead with his recommended repairs. He was also upset with us because we did not employ him to install the unit when we built the house. We explained that the initial install was not our decision. The builder used their own Daikin contractor. We tried using other Daikin dealers but no one would touch it. All told us to use our local Daikin dealer. But he refuses to help us. We tried a number of independent technicians but they were bewildered as to why the cooling wasn’t working. Eventually one independent technician persisted and he replaced some type of thermostat. The cooling just kicked in. He also said the control panel was incorrectly wired by one of the Daikin dealers. Prior to this we could never select our fan speed. It was always on high. The persistent good technician also redesigned our ductwork to allow for mor air to be moving into the unit. The unit suddenly started to work more efficiently. Defrost was still happening but not nearly as often but everything was working quite well. But then last winter the green light started blinking and the unit kept shutting down at random. It can work for weeks, days and hours. It can then shut down at random. The good technician replaced the Hp switch/ valve. It worked quite a while But this winter it started again. Poor guys given up. We can’t get Daikin head office to send another technician. They keep telling us to use our local guy even though he refuses to come. No other Daikin dealer will come because he’s our local dealer. See our problem Sean?
Re: Desperate. Help Please
Aye, dosnt sound very fun.
I think I would be looking at speaking to larger companys that work for different manufaturers, maybe find someone within those companys that knows what their doing. Or look further afield for an independent specialist fault finder.
Re: Desperate. Help Please
The strange thing is that when they hear it’s a Daikin , they will often tell me to go through my local dealer. If anyone has any contacts in Daikin Australia, please let me know. I’d love to actually find a refrigeration engineer who does assessments for insurance companies. I live in a regional town. I’ve looked around to no avail. May just have to get rid off the unit, spend 15 k for a brand new unit. Rest assured it won’t be a Daikin! I’m not keen on that idea but I’m running out of options. Still open for more ideas or advice from the forum.
Re: Desperate. Help Please
The manual says: P3 -Malfunction of thermistor in switch box
Re: Desperate. Help Please
E3 fault code tends to be related to a high pressure fault. As this fault is occurring during the heating cycle, there may either be a blocked return air filter or dirt ingress and build up on the fan blade, which is causing a reduced airflow over the ducted air handling unit. If the unit appears to function reasonably well in the cooling mode and we know that you get some fairly high summer ambient temperatures, then it is less likely to be a faulty high pressure switch as this would probably trip out during high ambients. I would suggest getting the fan blade on the indoor unit checked and also check that the motor is operating on the correct speeds during the heating cycle. If the fan motor is stuck on the lowest fan speed, this moight also cause a high pressure trip out eventually. There are several possibilities that you need to get eliminated, once you can find a technician who is prepared to spend somme time on your system.

Our technician replaced the actuator High pressure switch last year and it worked reasonably well but every so often the light would blink and the unit would stop working again. All I had to do to get the unit running again was turn the unit off and then on at the control panel and it would start working for an indefinite amount of time - could be weeks, days and at the moment every half hour. We are desperate. The technician suggested we replace the entire unit.
We do not know what to else do. We’re in our 60’s and do not want to freeze during winter. We are in the early stages of winter in Australia already. Just need some expert opinions. Please help. Just nee
The model numbers are
RZQ160PV4A

Serial number:E005589
Manufacturing date: 07 3
You state that you have a split type system with a Ducted indoor fan coil but the model reference you give is for an indoor Cassette type fan coil. Also, the indoor and outdoor capacities are different, with a 14kW indoor fan coil and a 16kW outdoor condensing unit.
Are your details correct?
Re: Desperate. Help Please
.
A few things come to mind if as frank says the indoor and outdoor are mismatched it could cause issues from day one.
Your system has not worked properly from day one and from the sound of it it does sound like and installation issue.
The ducting has also been modified?
Add to that you have had issues with refrigerant charges (why would the refrigerant need to be replaced if the system was sound?)
I always tell somebody with an issue to go back to basics and your basics are the installation. I can't help with diagnostics because you do need to be there to see it but a miss-matched indoor / outdoor setup, altered ducting and refrigerant issues all add up to something from installation.
No help to you I'm afraid and you are between a rock and a hard place re the treatment you have received from Daikin, maybe a threat to escalate it with Daikin and warn them about the possibilities of bad press.
Do you have a consumer watchdog or a government body responsible for customer services? Do you have any TV shows that fight the corner of the little guy?
Maybe somebody on here can recommend a good engineer who could look at it? Australia is not that big is it? I bet someone can just pop over and do a visit :D
All the best

Sensei,
I don't know what your problem is, but whatever you do, do not spend $15k on another new system.
Put in one or two split systems if it can't be resolved in the areas you use the most.
I don't know how big areas you want to heat up, but you don't need to heat the whole house, do you?
Make sure has good warranty, 3 years or more on unit & inverter, keep it simple, no running pipes everywhere, have outdoor unit basically just outside the wall if you can.
Price must include supply of air con unit, installation, electrical, no more to pay.
A retired couple did this & sit & suffer, worrying to turn on due to expense, especially if home all day.
Leave existing unit & maybe keep on investigating & use it for what it does best.
Because you are remote it will be more expensive, note you should get, a 5 year installation warranty, as this should be standard.
Also consider going on A Current Affair, seems to work for a lot of others, mention that to Daiken jokingly, see what their reaction is.
The split system may not look as good, but all your eggs not in one basket.
Re: Desperate. Help Please
Thank you so much to all who addressed my a/c problem. My wife snd I really appreciate the forum’s input. We will ring Daikin head office again tomorrow. We will take it to the mass media if they do not address our issue.
Re: Desperate. Help Please
Well we rang Daikin. We explained our dilemma and requested a technician. I said we were desperate and seriously thinking about contacting the media. We were assured by Daikin that a service coordinator would be contacting us during the week. We waited the entire week and no one rang. What an absolute joke this company is!

Thanks Ranger. You make sense. I’ll call again on Monday. ����
Re: Desperate. Help Please
The specifications I provided are what’s on the outdoor unit.

Are your details correct?
The specifications are what’s on the manufacturing label on the condenser.

It''s the indoor model details that don't look right
Re: Desperate. Help Please
Hmmmmmm. That’s interesting Frank. I haven’t the faintest idea. If we ever get the Daikin tech out. I’ll
certainly ask him.
Re: Desperate. Help Please
If you look at the indoor unit, it too has a model sticker similar to the outdoor unit
Re: Desperate. Help Please
Any photos of the indoor unit and ducting
Re: Desperate. Help Please
Not keen to get up in the roof - back issues.
