Error code CH61 - CONDENSER PIPE HIGH PRESSURE. This can be due to overcharging of the system or the condenser clogged with dust or an obstruction, or condenser fanmotor not working. Hope this helps.

Ohm the motor for a short or a ground. These units use VFDs and may have a problem a problem in the inverter section.A leak will cause the low pressure switch to open and shut the compressor down. Call a technician to look at it; Knowledge and the proper tools are needed here. No these units do not have capacitors in the condensing unit.

This could be any number of problems depending on whether this unit is a heat Pump or not. It sounds like it is a heat pump, if so it should have a defrost board or Control of some type. They also usually have a defrost or ice sensor on the outdoor Refrigerant coil. When ice or heavy frost is detected it puts the unit into defrost. This Could be why your unit is cycling off, the sensor could be bad or the board could be Bad. Also be sure your air filters are clean and the indoor and outdoor refrigerant Coils are clean. This may require you to remove the unit and hose it out.

Length can be any thing you want....EXCEPT both pipes MUST increase to the next LARGER size every 25 feet.

Hi Jamie hig595, I suggest that you check around both machines to see if you can see any oil stains,: ie: inside the outdoor unit, where the pipes are connected to the outdoor machine and indoor machine, or even around the outdoor case itself. Any oil stains would suggest that your system has lost gas and therefore you will need a serviceman. If thge machine will run at all are the fans working? hope this is helpful,regards Col
