tosh super multi r407c -3 pipe- were a f**ker for comp failures- 2 compressors on 1 shell, weighed about 80kg- took 4 hrs to remove electrics-boards etc-then undo the reactor on top then split the acoustic enclosure.
then u see the 1 3/8 common suction silver soldered onto the steel comp stubb-at 12 inch high-
had 3 comp changes 10r ago-

You can download the full manual HERE.

If you look on pg 91 you will find the flowchart for troubleshooting H01.

But generally, the second code will tell you which compressor tripped and then it's just basic faultfinding.
Does the windings have the right resistance?
Is the compressor down to earth?
Is the inverter's output OK?

Happy hunting!

The outcome was, compressor 2 was faulty even though it metered out ok, not down to earth and inverter output ok. Replaced compressor, all up and running now.

The job is not complete until you diagnose the cause of failure of the compressor or you may have another service call soon.

metered out ok-multimeter the windings or insulation test? could have been siezing up to cause the problem-have u done an acid test on the oil?
