I've been using the Daikin inverter board checker tool recently and have had good experiences with it. Sometimes it's across a roof and down a ladder, so it's good to know how to quickly manually check these boards. I would love to see a video on your procedures when you change a compressor. So much of the way I work on these machines has been through self-taught pain and suffering; I appreciate you all taking the time to create this content.
Got a part number for that tool?
Great video. Really like your VRV content 🇬🇧
Great content!! Please keep the videos coming!
Excellent explanations. Thanks!
Great information and thanks for sharing.
Thank you for sharing this instructive video
Glad it was helpful!
Thank you so much
good video, thanks for the knowledge
Any time!
I service mitsubishi and have changed inverter boards it seems there are some small differences between diakin and mitsubishi but I found this video very helpful thanks
What sort of differences?
Very good
Very informative! Anything on LG?
Nice video but next time please focus the camera to where you guys put the prods of tester .
Very informative
Thanks for the heads up! We'll definitely keep an eye on the camera focus next time so you can see exactly where we put those prods.
@13:42. With all the wires disconnected from the compressor, not touching anything and then run the Power Transistor Check mode 28, one lead to the disconnected wires either U, V or W and the other lead to the Ground check? Multimeter in DC voltage check mode? Thank you
Ok my question on this topic, i know you can turn off and inverter board via the mode settings ; and i did that and the unit ran without problem however after i took the bad board out to to take to the supply house the unit has an error as it says it cannot communicate with the said board. So i guess the setting isnt a full deactivation and is more a prevent it from running?
Did the unit run or shut down due to the error code?
@@qomco it shutdown
I do not understand here...isn't an inverter circuit ment to convert DC to AC...!!!! The scroll compressors I've seen on Heat pumps eg..Toshiba SMMS-i versions are rated with DC Voltage ...Please if coild clarify for me as I am still a rookie ..Thank you
