Nordyne review: 2 year old cassette hvac went out of service... Still out of service 11 months counting

Main complaint appears inherent with the industry (Rheem & Nordyne same time same story) Factory will only talk with dedicated wholesaler; wholesaler will only talk to licensed HVAC "professional"; That person is busy making a living without time to urinate uphill.
Part of the most recent inquiry on Nortek Golbal DC Inverter U-Match Series Cassette Type GXH18 (5.3 US V4DH) ..
This unit was installed, operated for a period of time - about two years - without incident. At the time of scheduled service an Error Code developed combined with the unit shutting itself off. The unit has not been operational for more than eleven months. The service technician has done his very best at least four times - new parts, cleaning, cussing. Nothing helped.

Your RE Michael Orlando - is the intermediary with 'Green Dog A/C' . Most recently you / they provided a new Cassette unit. The technician swapped out parts (the second control board) then left thinking it was fixed. A half hour or fourtyfive minutes later error code E-9 reappeared, the unit shut down, the technician hasn't resurfaced - and I can understand why.
