ACRD602 Refrigerant issues
Hi all,
We've had an issue with an ACRD602.
Low side pressure lowers to 480kpa and does not fault. High side maintains 2600kpa. We believe the E.E.V is not correctly regulating as load increases. Compressor increases speed to 70hz and continues at these pressures.
We have tested E.E.V coil resistance and this measures ok. All temperature and pressure sensors are reading accurate. We believe the output from motherboard is not correct, is there a way to test this?
