HVAC⎪HVACR⎪REFRIGERATION VIDEOS In this video I diagnose what's wrong with a Daikin Air Conditioner displaying an E5 fault code. Marac Services Pty Ltd Located in Sydney.
The two screws floating around in the bottom of the board enclosure are meant to attach the heatsink to the board along with thermal paste, if the screws aren't installed and new paste wasn't applied that replacement board never had a chance.
As soon as I saw those screws I knew exactly where they were from. Like you said, they’re the ones that screw the board down to the heatsink. You make a good point about the thermal paste, there is a good chance it wasn’t applied and even if it was, it probably isn’t a good contact. I replaced that unit today so I actually have this old unit in the back of my van as we speak so I can see if thermal paste was applied.
@maracservices Hey mate! The 7 on the remote is actually a T for test! With an e5 fault the high chance of compressor seizure with your failed board, good call with the condemn of unit Would have been good to see if you had a strong insulation resistance reading or not
Problem with this scenario , you now quote client on new inverter PCB because compressor windings measured good. Client gives go ahead for new inverter PCB. You install new PCB only to find compressor has seized. Now Daikin wont return the PCB as it has been installed and client has to fork out the cash for compressor. At this stage it would have probably been more cost effective to install new unit with 1 year warranty. I always quote replacement of compressor + inverter PCB vs new unit.
I would do the same thing Craig You never get any thanks from anyone by faulting the pcb then ordering them come back to replace the part to find out it’s another part that’s in fault also Would always advise to replace the whole outdoor unit which comes with warranty
Very true with all inverter compressors as damned if you do damned if you don't its a proper catch scenario I would quote for new out door as long as you can get the outdoor as they change to a new aircon model so then it's a new whole install and like he said it looks like it's had a new board in it's past or someone has been looking at it !!! I prefer working on refrigeration to be fair and only installing air-conditioning because even advice off Daikin and they say it's the board but it could be the inverter compressor wtf as you have to tell the customer ffs which doesn't sound reassuring 🤬
its nice to see an old girl every now and then. Whats the difference between the FTXS60FVMA and FTXS60GVMA i Have both and for the life of me i can't tell.
They’re the same just manufactured at different times. I can confirm they have the same cover and evaporator and I assume everything else is identical.
@@maxd4968 yeah the bvma and jvea was made way earlier than these they were one of the first types if daikin inverters they were replaced to fix the bad inverter design and the fact that most of them still used r22
I honesty don’t know what the manufacturers warranty is. A lot of manufacturers don’t warrant it once the packet is opened and I’m not even kidding haha. I think they’re covering themselves from hacks incorrectly installing parts and incorrect diagnosing. That’s not the consumers issue though because if the part doesn’t work from incorrect diagnosis then the air con repairer will wear that. So it’s important for the repairer to be pretty confident before buying parts. I think most air conditioning companies give 12 months warranty on their work.
Daikin’s will keep you in a job for life Over priced units ,the quality has gone down hill massively in the last 15 years Would always advise my customers to go Mitsubishi electric
You know you have a low quality units when the data plate is a label and is peeling off at 10 yrs…all units nowadays. Did you check communication? Install surge protector.
This unit was definitely over 15 years old. I couldn’t check for communication because the outdoor board was dead. I replaced the entire unit on Saturday
appareil photo e5 mechanical compressor lock possible to turn off the device is closed electrical switch in off mode in more than 6 hours after turning on your device it was working. 
just swap out the outdoor unit. This board swapping is the road to hell. I've got a 2016 12.5kw unit with a bad board and I won't just swap boards. Its new condenser or nothing from me.. Been bitten too many times by Daikin to play those games. Esp when the price of parts+ time+ no warranty fitting matches the cost of a new outdoor unit with warranty.
@@richardbartlett6932 I have a genuine question, where do you get an outdoor unit for older models? I’d love to change the whole outdoor. That would be amazing, just as far as I knew that wasn’t an option. Daikin only stock current models (as far as I’m aware).

Friday also had an RX50 with E5 error code - no refrigerant in system, windings measured fine - compressor had seized.
RX50's are just unreliable -

The top right screw had seat sink on the threads. How the previous tech didn't see that is wild

@@J.k313 crazy stuff!
@@maracservices Please give us a report on the thermal paste.
A interesting fault Mitchell, i look forward to the next episode 🤔

Love the videos Mitch. Learning a lot, thank you. Keep them coming please 👍
Thanks mate. I think you will like the next one then. Cheers
@@maracservices Can’t wait to see it. Big fan from the UK.

I get what you’re saying. You’ll be happy to know I replaced the entire unit on the Saturday just past.
I would do the same thing Craig

Hi, Mitch. Have you seen a faulty inverter board and a seized compressor at the same time?
I have not, only one or the other to be honest .
its nice to see an old girl every now and then.
Whats the difference between the FTXS60FVMA and FTXS60GVMA i Have both and for the life of me i can't tell.
They’re the same just manufactured at different times. I can confirm they have the same cover and evaporator and I assume everything else is identical.
@@maracservices yeah the only notice that the outdoor unit has a different Daikin inverter logo it took me a while to notice
@@GeneralAvitation I have a ftxs60bvma and it is quite different to this
@@maxd4968 yeah the bvma and jvea was made way earlier than these they were one of the first types if daikin inverters they were replaced to fix the bad inverter design and the fact that most of them still used r22
Is that a daikin specific inverter checker? I have a refco brand, not sure on its compatability with different brand units though.
It’s all good, yours will work with everything. I bought mine from Daikin but they’re all the same. Mine doesn’t have any branding on it.
I have Refco checker and works fine
Hi Mitch, how many years is warranty for changing parts.pcb board etc
I honesty don’t know what the manufacturers warranty is. A lot of manufacturers don’t warrant it once the packet is opened and I’m not even kidding haha.
I think they’re covering themselves from hacks incorrectly installing parts and incorrect diagnosing.

So it’s important for the repairer to be pretty confident before buying parts.

@@maracservices I don't do warranty on inverter boards unless the supplier does warranty
Daikin’s will keep you in a job for life
Over priced units ,the quality has gone down hill massively in the last 15 years
Would always advise my customers to go Mitsubishi electric
Hey Mitch how do we get one of those tools?
I bought mine from Daikin however you can buy them online. Just search inverter checker. 👍🏻

In the case of Japan, only certain people can get checkers.
So I connected three analog testers in parallel and made an original checker😂
