I’d rather work on a system like this where I can trace faults than the bullshit u get with Daikin error code flow chart where u end up replacing every single board and the outdoor fans
It’s crazy that some of the end results to their flow charts is just replace boards 😂 Mitsubishi are a bit better in that they have testing points and voltages in their service manuals.
The CCH had no reading to earth. I tested everything and the only issue I found was the RV coil. Higher resistance shouldn’t mean more current to blow the fuse however. The terminals on the fuse were also loose. My feeling is a combination of both those things.
You can press the down button on the PCB to do a speed up to bypass the 2 minute timer 👍
Good to know. Thanks mate.
Those hevac controls there proportional bands are a. Pain for that reason

So what actually caused the fuse blown? The solenoid valve or the crankcase heater? Thanks
