Anyone experiencing failures on compressors manufactured around 2005-6, to be specific IGBT (inverter), dc-dc converters and backplane failures. The compressors failing are fully integrated no dramas with the semi-integrated compressor models. Last time I did training the only part requiring replacement was capacitor banks. Shelf life of 5-10 years if memory serves. Do other components have shelf life??
Also please note always check dc bus after 10-15 minute power down , I have had bleed resistors fail on these machines.
Any input appreciated.
