daikin split cycle airconditioner model rxd71Jvea

[hudsonhawke]

I have just been advised by a tech that the code presented on this unit has a code H27? in short the compressor is dead. He suggested I buy another split air conditioner as it wasn't worth repairing. Is the tech right with his diagnosis or can I replace the compressor. This unit is 10 years old and only used been usedon extreme temperature days . The compressor died on a day the temperature was 38-40 degrees celcius.

theres a few factors to consider here,

if the system is ten years+ parts may be difficult to source

what refrigerant the old system is, will it be replaced with a more energy efficient so running cost can be lower that can be offset against new install.g from R22 to R410A will be more energy efficient

is this the first of many problems to come

also if the system is in the UK there also UK F gas regs to take into account if the system is R22

h27 isnt a daikin fault code.
check the compressor hasnt overheated and cut out on internal klixon

Daikin fault codes are 2 characters, not 3, so it can't be H27, could be H7 for example.
The JVEA units aren't very good, parts are expensive, so I'd buy a new unit instead of repairing myself.
