WARRANTY. Found system non operational upon arrival. Customer showed me error code 76.2 on his phone. Unit is a 2 zone mini split Fujistu Haylcon. Checked unit for leaks and low charge. Checked for power to unit. Error code is to outdoor thermistor valve. Removed exposed thermistor and cleaned. No change. PCB on unit shows error code with six flashes. Unable to find data sheet for translation of code. Looked up online and found no answers. Called a couple people very familiar but they advised to contact tech support or someone more familiar with fujistu. Unit non operational upon departure.
