Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do. THe flash code indicates that the low pressure or high pressure switch has cut the compressor off twice within one hour.Our first step is to determine whether it is high pressure or low pressure switch that is shutting unit down.Do you have refrigerant gauges so we can watch to see what pressures are when compressor shuts down?
Reasons causing the error can be low charge, a restriction,dirty filters, indoor or outdoor fan not coming on or moving sufficient air, or a defective metering device,
If both fans are coming on we will probably need the gauges to troubleshoot.
